[New-bugs-announce] [issue38399] Error message persists when reimporting library

[AwesomeCronk]

New submission from AwesomeCronk <awesomecronk at gmail.com>:

I am working on a hexdump library in Python 3.7.4.
Whenever an issue is triggered, the error message shows up. I can usually edit and correct the file(library), but when I reimport the library and rerun the function, it throws the same error on the same line number, even if the line was removed or commented out.
