Python: source code string cannot contain null bytes

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.

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)).

  • 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 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.

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.

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.

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...

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.
