Source code string cannot contain null bytes ошибка - Не ошибается лишь тот, кто ничего не делает!

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)).

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

I created a file using windows terminal echo «hello» > hello.py and got this issue. I resolved by creating a new file from notepad

My problem was the python interpreter, try changing it to the right python directory path

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?

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.
