I’m using Max OS X 10.10.3, and I finally got the graphics.py to show in Python 3, before it was saying no module existed.
However, now when I try import graphics, or from graphics import *, I get the message:
"source code string cannot contain null bytes"
Does any Mac user (using Python 3) perhaps know what is wrong? Has anyone used the Zelle book and his graphics.py module? Thanks.

For posterity: I had the same problem and fixed it using,
sed -i 's/x0//g' FILENAME
The file seemed to be messed up in numerous ways (wrong endings, etc); no idea how…

I am using Visual Studio Code, the encoding was set to UTF-16 LE.
You can check the encoding on the right bottom side of VSCode. Just click on the encoding and select «save with encoding» and select UTF-8. It worked perfectly.

I got this message when I wanted to use eval for my input for my function that sometimes it takes string or int/float but when it takes numpy numbers, it throws this exception, eval(number).
My solution was eval(str(number)).
answered Aug 5, 2019 at 6:09
I just encountered this problem, which is usually caused by the encoding format. You can use Notepad++ to change the encoding format of python files to UTF-8.

This kind of error is not from your project source code. This kind of error emerges from your python interpreter. So the best solution is to set your python interpreter in your project env directory. or set the interpreters virtual env properly using your IDE’s interpreter configuration.

Open your file with an editor that can show you all invisible character.
You will see where is the invalid char, just delete and re-type it.
If you are on mac you can do it with Coda > Open your file > Show invisible characters.

- Go to python folder
python36/Lib/site-packages/scipy/ - Open
__init__.py
Change:
from scipy._lib._testutils import PytestTester
to:
from scipy._lib.test__testutils import PytestTester
It worked on my windows 7

Do you experience getting the error message “source code string cannot contain null bytes“, whenever you attempt to import graphics, or from graphics import *? .This warning message is shown if the contents of the file include a byte that has a value that is a null value.
What is ValueErrror?
ValueError is the error in python that mostly occurs when you are passing the argument to the built-in functions of the right type. But the value of that argument is invalid. For example, suppose the function accepts an argument of integer type. And you are passing the value by converting the string to an integer. In this case, you will get the ValueErrror.
Solution for the source code string cannot contain null bytes
If you have been experiencing “source code string cannot contain null bytes” problem, then the following possible options may help you fix it:
Solution 1: Remove the null character
Remove the null character at the end of line 41 in the cTurtle.py because, for some unknown reason, line 41 of the cTurtle.py file includes a null character:
$ od -t a cTurtle.py.orig | grep -i nul 0003360 - - - - sp c T u r t l e . p y nul
After the removal of the null character, the module’s operations should go back to their normal state.
Solution 2: Use the sed command
If you want to remove the null characters that are in a file, you may do it quickly and simply by using the sed command that is indicated in the following example:
sed -i 's/x0//g' FILENAME
This method modifies the file in situ, which is critical if the file is still being used. Passing the parameter -i’ext’ generates a backup of the original file with the ‘ext’ suffix appended to it.
Solution 3: Use pipeline
In the event that the output of sed indicates that nothing was replaced, then you may make use of the following pipeable one-liner using Phyton:
python -c 'import sys; sys.stdout.write(sys.stdin.read().replace("", ""))'
You may also discover that some instructions do, in fact, leave the null bytes in place, despite the fact that they are no longer visible, at least not in a terminal running OS X. Hexdump is a useful tool for debugging situations like these.
Conclusion
ValueError is a python exception error that you will get when you are passing the argument to the function of an invalid type. The Valueerror: source code string cannot contain null bytes also comes due to this case. The above method will solve your problems regarding this error.

ValueError: source code string cannot contain null bytes
Since I am a Noob,I can’t understand the error here,can someone please explain what is wrong and how I can solve that
Many people ask questions like this, BUT many of them are using not standart library, so their error can be explained (for me). I used standart Tkinter library but i get this error too.
File "C:/Users/Panda/Desktop/Пайтон/enter_symbol.py", line 5, in <module>
exec(f'tk.bind({chr(num)},lambda event:print("You entered:",{chr(num)}))')
ValueError: source code string cannot contain null bytes
My code:
from tkinter import Tk
tk=Tk()
tk.geometry('0x0+0+0')
for num in range(1000):
exec(f"""
try:tk.bind({chr(num)},lambda event:print("You entered:",{chr(num)}))
except:None""")
What should I do to not get this error?
Вопрос:
Я использую Max OS X 10.10.3, и я наконец получил graphics.py для показа в Python 3, прежде чем он сказал, что модуль не существует.
Однако теперь, когда я пытаюсь выполнить import graphics или from graphics import *, я получаю сообщение:
"source code string cannot contain null bytes"
Может ли любой пользователь Mac (используя Python 3) знать, что не так? Кто-нибудь использовал книгу Zelle и его модуль graphics.py? Спасибо.

См. qaru.site/questions/89525/…
Ответ №2
Я только что столкнулся с этой проблемой, которая обычно вызывается форматом кодировки. Вы можете использовать Notepad++, чтобы изменить формат кодирования файлов Python на UTF-8.
Ответ №3
Откройте свой файл с помощью редактора, который может показать вам всех невидимых символов. Вы увидите, где находится недопустимый символ, просто удалите и введите его заново.
Если вы работаете на Mac, вы можете сделать это с помощью Coda> Открыть файл> Показать невидимые символы.
Ответ №4
Я использую код Visual Studio, кодировка была установлена в UTF-16 LE. Вы можете проверить кодировку в правой нижней части VSCode. Просто нажмите на кодировку и выберите “сохранить с кодировкой” и выберите UTF-8. Это сработало отлично.
Ответ №5
- Перейти в папку python
python36/Lib/site-packages/scipy/ - Открыть
__init__.py
Изменение:
from scipy._lib._testutils import PytestTester
в:
from scipy._lib.test__testutils import PytestTester
Он работал на моих окнах 7
Ответ №6
Я получил это сообщение, когда хотел использовать eval для ввода своей функции: иногда он принимает строку или int/float, но когда он принимает числа numpy, он выдает это исключение, eval(number).
Мое решение было eval(str(number)).
Ответ №7
Эта ошибка возникает не из исходного кода проекта. Такая ошибка возникает из вашего интерпретатора python. Поэтому лучшим решением является установка вашего интерпретатора python в каталог env. или правильно настроить интерпретаторы виртуального env, используя конфигурацию интерпретатора IDE.
Ответ №8
У меня такая же ошибка, и решение состоит в том, чтобы удалить библиотеку, и если вы не можете просто удалить ее и переустановить библиотеку. должен работать, он работает для меня…

Answer by Davis Kline
I’m using Max OS X 10.10.3, and I finally got the graphics.py to show in Python 3, before it was saying no module existed.,To find the implementation of any python operator, first find out what bytecode Python generates for it, using the dis.dis function:,Another possibility is to write a simple Python script that reads the file and removes the null bytes use the string replace method:,The in operator becomes a COMPARE_OP byte code. Now you can trace how this opcode is being handled in the Python evaluation loop in Python/ceval.c:

Answer by Aryan Butler
(You can also just construct your particle effect via code–but that’s a much longer, more tedious, and less intuitive way of doing things.),Of course, this is all to be done only if Mac doesn’t let you just run the program directly from the file-manager, perhaps by double-clicking it, or by right-clicking it and selecting “run”.),Ah. You seem to be attempting to load an image as a particle effect. What “loadConfig” expects is instead a particle-definition file, such as saved from the Particle Panel sample-application.,I don’t use Mac, I’m afraid, so I don’t know where Panda gets installed on that platform. :/
Hi quick question, why does this error keep popping up when I try to do particle effects?
