class TestClass(object):

    def __init__(self):
        pass

    def __del__(self):
        with open('log', 'w+') as fL:
            fL.write('__del__')


if __name__ == '__main__':
    test = TestClass()

Ran the script and got the error message: NameError: name 'open' is not defined

Works fine for me. Can you give any more information? – Ariel A Apr 05 '20 at 04:46
Please include the _full_ error message. – DYZ Apr 05 '20 at 04:47
@DYZ Exception ignored in: Traceback (most recent call last): File "test.py", line 7, in __del__ NameError: name 'open' is not defined – user11944945 Apr 05 '20 at 07:40
Do not call your files `test.py`. – DYZ Apr 05 '20 at 07:41
@DYZ I renamed the file and got the same error message. – user11944945 Apr 05 '20 at 07:43
Also remove the folder `__pycache__`, if any, and restart python. – DYZ Apr 05 '20 at 07:45
@DYZ It didn't help to delete __pycache__. Is the issue reproduced at your side? – user11944945 Apr 05 '20 at 07:47
@Ariel A What information do you need? – user11944945 Apr 05 '20 at 07:48
No, it works fine. Is this the full code that you run? No other `import`s, etc.? – DYZ Apr 05 '20 at 07:53

@DYZ It's the full code. I got the same error on my Windows 10 and Ubuntu. – user11944945 Apr 05 '20 at 07:55
@DYZ It works fine on python2. – user11944945 Apr 05 '20 at 08:00
Can you `open` any files at all? – DYZ Apr 05 '20 at 08:09
@DYZ Yes, I can. – user11944945 Apr 05 '20 at 08:22
