When I issue a warnings.warn() warning in python, the output to stderr includes not just my warning method, but also the offending line from the source code. I would like to suppress this line from the source code, as it really detracts from expressing the warning clearly. Does anyone know how to do this?

Take a look at warning filters - https://docs.python.org/2/library/warnings.html#the-warnings-filter – shaktimaan Aug 27 '14 at 21:09

You can monkey-patch the formatwarning function. If you look at the source, it shouldn't be too hard to write a replacement that doesn't have a line number there.

2Monkey-patch just means modifying a function or object without changing its source. – Alex Kaszynski Jan 10 '20 at 21:57
