Why my python just throw an error call:

code, fname = _get_code_from_file(run_name, path_name)
File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/runpy.py", line 239, in _get_code_from_file
code = compile(f.read(), fname, 'exec')
ValueError: source code string cannot contain null bytes

It was fine yesterday and it just have problem today.

It was never happened before and I don't know What is null bytes

Other people have this problem are all because using UTF-16 etc. but I'm really using UTF-8 and it really made me headache.

My IDE is VSCode and I'm using UTF-8

  • @balu I do like what he said, copy+paste, but the problem was still there. and I'm not using UTF-18, instead, I'm using UTF-8. I'm not pro of python and I don't know other problem in my program. Commented Feb 23, 2022 at 7:15
  • check what is there in line 239 of the .py file . open in notepad++ and see for any hidden chars that might have crept. Commented Feb 23, 2022 at 7:24
