Syntaxerror invalid character in identifier ошибка в питоне

The error SyntaxError: invalid character in identifier means you have some character in the middle of a variable name, function, etc. that’s not a letter, number, or underscore. The actual error message will look something like this:

  File "invalchar.py", line 23
    values =  list(analysis.values ())
                ^
SyntaxError: invalid character in identifier

That tells you what the actual problem is, so you don’t have to guess «where do I have an invalid character»? Well, if you look at that line, you’ve got a bunch of non-printing garbage characters in there. Take them out, and you’ll get past this.

If you want to know what the actual garbage characters are, I copied the offending line from your code and pasted it into a string in a Python interpreter:

>>> s='    values ​​=  list(analysis.values ​​())'
>>> s
'    values u200bu200b=  list(analysis.values u200bu200b())'

So, that’s u200b, or ZERO WIDTH SPACE. That explains why you can’t see it on the page. Most commonly, you get these because you’ve copied some formatted (not plain-text) code off a site like StackOverflow or a wiki, or out of a PDF file.

If your editor doesn’t give you a way to find and fix those characters, just delete and retype the line.

Of course you’ve also got at least two IndentationErrors from not indenting things, at least one more SyntaxError from stay spaces (like = = instead of ==) or underscores turned into spaces (like analysis results instead of analysis_results).

The question is, how did you get your code into this state? If you’re using something like Microsoft Word as a code editor, that’s your problem. Use a text editor. If not… well, whatever the root problem is that caused you to end up with these garbage characters, broken indentation, and extra spaces, fix that, before you try to fix your code.

SyntaxError: invalid character in identifier

Process finished with exit code 1

Here’s everything about SyntaxError: invalid character in identifier in Python.

You’ll learn:

• The meaning of the error SyntaxError: invalid character in identifier
• How to solve the error SyntaxError: invalid character in identifier
• Lots more

So if you want to understand this error in Python and how to solve it, then you’re in the right place.

Let’s get started!

The error SyntaxError: invalid character in identifier occurs when invalid characters somehow appear in the code. Following is how such a symbol can appear in the code:

• Copying the code from the site such as stackoverflow.com
• Copying from a PDF file such as one generated by Latex
• Typing text in national encoding or not in US English encoding

Problematic characters can be arithmetic signs, parentheses, various non-printable characters, quotes, colons, and more.

You can find non-printable characters using the repr() function or special text editors like Vim. Also, you can determine the real codes of other characters using the ord() function.

However, you should copy the program text through the buffer as little as possible.

This habit will not only help to avoid this error but will also improve your skills in programming and typing. In most cases, retyping will be faster than looking for the problematic character in other ways.

Let’s dive right in:

First, What Is an Identifier in Python?

The identifier in Python is any name of an entity, including the name of a function, variable, class, method, and so on. 

PEP8 recommends using only ASCII identifiers in the standard library. However, PEP3131 allowed the use of Unicode characters in identifiers to support national alphabets. 

The decision is rather controversial, as PEP3131 itself writes about. Also, it recommends not using national alphabets anywhere other than in the authors’ names.

Nevertheless, you can use such variable names, and it will not cause errors:

переменная = 5
變量 = 10
ตัวแปร = 15
print(переменная + 變量 + ตัวแปร)

30

Don’t Blindly Copy and Paste Python Code

Most often, the error SyntaxError: invalid character in identifier occurs when code is copied from some source on the network. 

Along with the correct characters, you can copy formatting characters or other non-printable service characters.

This, by the way, is one of the reasons why you should never copy-paste the code if you are looking for a solution to your question somewhere on the Internet. It is better to retype it yourself from the source.

For novice programmers, it is better to understand the code fully and rewrite it from memory without the source with understanding. 

Zero-Width Space Examples

One of the most problematic characters to spot is zero-width space. Consider the code below:

def bub​ble(lst): 
  n = len(lst) 
  for i in range(n):
    for j in range(0, n-i-1):
      if lst[j] > lst[j+1]:
        lst[j], lst[j+1] = lst[j+1], lst[j] 
  
print(bubble([4, 2, 1, 5, 3]))

File "<ipython-input-18-b9007e792fb3>", line 1
    def bub​ble(lst):
              ^
SyntaxError: invalid character in identifier

The error pointer ^ points to the next character after the word bubble, which means the error is most likely in this word. In this case, the simplest solution would be to retype this piece of code on the keyboard. 

You can also notice non-printable characters if you copy your text into a string variable and call the repr() function with that text variable as an argument:

st = '''def bub​ble(lst): 
  n = len(lst) 
  for i in range(n):
    for j in range(0, n-i-1):
      if lst[j] > lst[j+1]:
        lst[j], lst[j+1] = lst[j+1], lst[j] 
  
print(bubble([4, 2, 1, 5, 3]))'''

repr(st)

'def bub\u200bble(lst): \n  n = len(lst) \n  for i in range(n):\n    for j in range(0, n-i-1):\n      if lst[j] > lst[j+1]:\n        lst[j], lst[j+1] = lst[j+1], lst[j] \n  \nprint(bubble([4, 2, 1, 5, 3]))'

You see that in the middle of the word bubble, there is a character with the code u200b.

This is exactly the zero-width space. It can be used for soft hyphenation on web pages and also at the end of lines.

It is not uncommon for this symbol to appear in your code if you copy it from the well-known stackoverflow.com site. 

Detect Non-Printable Characters Examples

The same problematic invisible characters can be, for example, left-to-right and right-to-left marks.

You can find these characters in mixed text: English text (a left-to-right script) and Arabic or Hebrew text (a right-to-left script). 

One way to see all non-printable characters is to use special text editors. For example, in Vim this is the default view; you will see every unprintable symbol.

Let’s look at another example of code with an error:

a = 3
b = 1
c = a — b

File "<ipython-input-11-88d1b2d4ae14>", line 1
    c = a — b
          ^
SyntaxError: invalid character in identifier

In this case, the problem symbol is the em dash. There are more than five types of dashes. In addition, there are hyphenation signs and various types of minus signs. 

Try to guess which of the following characters will be the correct minus:

a ‒ b # figure dash
a – b # en dash
a — b # em dash
a ― b # horizontal bar
a − b # minus
a - b # hyphen-minus
a ﹣ b # small hyphen minus
a － b # full length hyphen minus

These lines contain different Unicode characters in place of the minus, and only one line does not raise a SyntaxError: invalid character in identifier when the code is executed. 

The real minus is the hyphen-minus character in line 6. This is a symbol, which in Unicode and ASCII has a code of 45.

You can check the character code using the ord() function.

However, if you suspect that one of the minuses is not a real minus, it will be easier to remove all the minuses and type them from the keyboard. 

Below are the results that the ord() function returns when applied to all the symbols written above. You can verify that these are, indeed, all different symbols and that none of them is repeated:

print(ord("‒"))
print(ord("–"))
print(ord("—"))
print(ord("―"))
print(ord("−"))
print(ord("-"))
print(ord("﹣"))
print(ord("－"))

8210
8211
8212
8213
8722
45
65123
65293

By the way, the ord() function from the zero width space symbol from the bubble sort example will return the code 8203.

Above, you saw that this symbol’s code is 200b, but there is no contradiction here. If you translate 200b from hexadecimal to decimal, you get 8203:

ord("​")

8203

More Non-Printable Characters Examples

Another example of a problematic character is a comma. If you are typing in Chinese, then you put “，”, and if in English, then “,”. 

Of course, they differ in appearance, but it may not be easy to find the error right away. By the way, if you retype the program on the keyboard and the problem persists, try typing it in the US English layout. 

The problem when typing can be, for example, on Mac OS when typing in the Unicode layout:

lst = [1, 2, 3]
lst += [4，5，6]

File "<ipython-input-16-2e992580002d>", line 2
    lst += [4，5，6]
                ^
SyntaxError: invalid character in identifier

Also, when copying from different sites, you can copy the wrong character quotation marks or apostrophes.

Still, these characters look different, and the line inside such characters is not highlighted in the editor, so this error is easier to spot. 

Below are the different types of quotation marks. The first two lines are correct, while the rest will throw SyntaxError: invalid character in identifier:

st = 'string'
st = "string"
st = ‘string‘
st = `string`
st = 〞string〞
st = ＂string＂
st = ‟string‟

Another symbol worth noting are brackets. There are also many types of them in Unicode. Some are similar to legal brackets.

Let’s look at some examples. The top three are correct, while the bottom three are not:

tpl = (1, 2, 3)
lst = [1, 2, 3]
set_ = {1, 2, 3}
tpl = ⟮1, 2, 3⟯
lst = ⟦1, 2, 3⟧
set_ = ❴1, 2, 3❵

Another hard-to-find example is the wrong colon character. If the colon is correct, then many IDEs indent automatically after newlines. 

The lack of automatic indentation can be indirect evidence that your colon is not what it should be:

for _ in range(3)：
  print("Ok")

File "<ipython-input-25-6428f9dbfe4c>", line 1
    for _ in range(3)：
                     ^

In this Python tutorial, we will discuss to fix an error, syntaxerror invalid character in identifier python3, and also SyntaxError: unexpected character after line continuation character. The error invalid character in identifier comes while working with Python dictionary, or Python List also.

• In python, if you run the code then you may get python invalid character in identifier error because of some character in the middle of a Python variable name, function.
• Or most commonly we get this error because you have copied some formatted code from any website.

Example:

def check(x):
if k in range(4,9):
print("%s in the range"%str(x))
else:
print("not in the range")
check   （5）

After writing the above code, I got the invalid character in identifier python error in line number 6.

You can see the error, SyntaxError: invalid character in identifier in the below screenshot.

To solve this invalid character in identifier python error, we need to check the code or delete it and retype it. Basically, we need to find and fix those characters.

Example:

def check(x):
if k in range(4,9):
print("%s in the range"%str(x))
else:
print("not in the range")
check(5)

After writing the above code (syntaxerror invalid character in an identifier), Once you will print then the output will appear as a “ 5 in the range ”. Here, check (5) has been retyped and the error is resolved.

Check the below screenshot invalid character in identifier is resolved.

SyntaxError: unexpected character after line continuation character

This error occurs when the compiler finds a character that is not supposed to be after the line continuation character. As the backslash is called the line continuation character in python, and it cannot be used for division. So, when it encounters an integer, it throws the error.

Example:

div = 52
print(div)

After writing the above code (syntaxerror: unexpected character after line continuation character), Once you will print “div” then the error will appear as a “ SyntaxError: unexpected character after line continuation character ”. Here, the syntaxerror is raised, when we are trying to divide “52”. The backslash “” is used which unable to divide the numbers.

Check the below screenshot for syntaxerror: unexpected character after line continuation character.

To solve this unexpected character after line continuation character error, we have to use the division operator, that is front slash “/” to divide the number and to avoid this type of error.

Example:

div = 5/2
print(div)

After writing the above code (syntaxerror: unexpected character after line continuation character in python), Ones you will print “div” then the output will appear as a “ 2.5 ”. Here, my error is resolved by giving the front slash and it divides the two numbers.

Check the below screenshot for unexpected character after line continuation character is resolved.

This is how to solve python SyntaxError: invalid character in identifier error or invalid character in identifier python list error and also we have seen SyntaxError: unexpected character after line continuation character in python.

On this page, we are going to fix Syntax error “Invalid Character Identifier” in Python So let’s start.

The invalid character identifier is a type of syntax error that arises when the invalid characters appear in a code. This error may arise when you copy a code from a site, copy a code from a PDF, use alphabets anywhere in code, or type text in different national language codes.

The characters that can cause syntax error: invalid character identifier can be a parenthesis, arithmetic signs, colons, etc. identifier can be any code, function, or variable in a text.

To solve the issue, you should copy the program text by using a buffer as small in amount as possible. The use of a buffer will prevent this syntax error and also improve typing and programming skills.

Like any programming language, some rules should be in mind when you are using identifiers in Python.

• They should contain only numbers (0–9), alphabets (a-z or A-Z), and underscore(_).
• They cannot start with any number.
• The value should not be a keyword.

There are some other things that you have to follow,

• All identifiers except names start with an upper case.
• An identifier starting with an underscore is used to indicate that it is private.
• Identifiers starting with two underscores indicate that it is highly private.

Create your variables using these rules and conventions to avoid the ‘SyntaxError: invalid character in identifier’.

Here are some methods you can use to fix syntax errors: invalid character identifier.

Do Not Use National Alphabets

It is recommended that you should not use national alphabets anywhere other than in the author’s name. Nevertheless, you can use such variable names as the name of a person, and it will not cause an error.

For example

Christian = 5

William = 10

John = 15

print(Christian + William + John)

Output:

30

Do Not Copy And Paste a Python Code

Most often, the error Syntax Error: invalid character in identifier arises when the code is copied from some source already present on the network.

There is a chance for you to get errors like along with the correct characters you can copy formatting characters or other non-printable service characters.

When you copy from different sites, you can copy the wrong character quotation marks or apostrophes which cause errors.

This is one of the reasons why you should never copy-paste the code from any network.

If you are looking for a solution to your question somewhere on the Internet then you should retype it yourself even though taken from the source.

For the programmers who have just started learning Python, it is better to understand the code fully, learn information from it, and rewrite it from memory without the source.

Detect Non-printable Character

Non-printable characters are hidden and we cannot see them but they can cause syntax error: invalid character identifier. We can see all non-printable characters by using special text editors.

For example, Vim is the default view in which we will see every unprintable symbol.

Let’s look at the example of code with an error in it:

a = 3

b = 1

c = a — b

File "", line 1
c = a — b
      ^

Syntax Error: invalid character in an identifier.

In this case, there are more than five types of dashes and various types of minus signs in this code that are causing the error. We can remove it by limiting the use of signs. Another symbol worth noting is the use of brackets.

Here the top three are correct, while the bottom one is not correct.

tpl = (1, 2, 3)

lst = [1, 2, 3]

set = {1, 2, 3}

tpl = ⟮1, 2, 3⟯

The syntaxerror invalid character in identifier error message usually encounters when you’re working with Python.

If you are experiencing this error right now and don’t know how to fix it, continue reading.

In this article, we’ll delve into how to fix the invalid character in identifier in Python.

Apart from that, you’ll also discover new insights about this error.

The syntaxerror: invalid character in identifier error message occurs when you use an invalid character in the middle of a variable or function in your Python code from copying a certain code in other sources that have a formatted code.

This error indicates that you have some character in the middle of a variable name, function, etc. that’s not a letter, number, or underscore.

Moreover, this error message is the same as the following example code:

website = ‘Itsourcecode‘

Output:

 File "C:Userspies-pc2PycharmProjectspythonProjectmain.py", line 1
    website = ‘Itsourcecode‘
              ^
SyntaxError: invalid character '‘' (U+2018)

What is “identifiers”?

Identifiers are names given to variables, functions, classes, or any other element in a programming language.

In Python, identifiers can only have the following characters

✅ “0” to “9” (digits)

✅ “A” to “Z” (alphabets uppercase)

✅ “a” to “z” (alphabets lowercase)

✅ “_” (underscore)

Why does the “invalid character in identifier” SyntaxError occur?

This error can occur due to several reasons, which include the following:
👎 Using special characters, such as punctuation marks or mathematical symbols, in an identifier can trigger this error.

👎 Incorrect character encoding issue.

👎 File Format Incompatibility.

👎 Improper usage or mismatched quotation marks within identifiers

How to fix “syntaxerror invalid character in identifier”?

To fix the syntaxerror: invalid character in identifier, verify your code for any variable names that contain invalid characters. Ensure that all variable names start with a letter or underscore, and only contain letters, numbers, and underscores.

If you find an invalid character, you can either remove it or replace it with a valid character.

Solution 2: Rewrite the code

Rewriting the line in your code that causes an error is the best way to resolve this error.

It is the solution for the example code that we illustrate above.

For example:

website = 'Itsourcecode'
print(website)

Output:

Itsourcecode

In some cases, this error also occurs in mathematical operations.

For example:

sample_1 = 500
sample_2 = 150

result = sample_1 — sample_2

Output:

File "C:Userspies-pc2PycharmProjectspythonProjectmain.py", line 4
    result = sample_1 — sample_2
                      ^
SyntaxError: invalid character '—' (U+2014)

To fix the issue, change it to the correct language and rewrite the minus “-” sign.

Corrected code:

sample_1 = 500
sample_2 = 150

result = sample_1 - sample_2
print(result)

Output:

350

Solution 2: Check for invisible characters

Usually, invisible characters such as a zero-width space can cause this error. You can use the repr function to check for invisible characters.

And ensure that you are using the correct encoding when writing your code.

Conclusion

In conclusion, the syntaxerror: invalid character in identifier error message occurs when you use an invalid character in the middle of a variable or function in your Python code from copying a certain code in other sources that have a formatted code.

I ran this code and this doesn’t work, I’m using python 3 btw, I have checked the syntax a million times. I have installed all the necessary packages and all of them are up to date, here is the code I ran:

labels = [0, 0, 1, 1]
clf = tree.DecisionTreeClassifier()
