[Python-ideas] Make fnmatch.filter accept a tuple of patterns

[Andre Delfino]

Frequently, while globbing, one needs to work with multiple extensions. I’d
like to propose for fnmatch.filter to handle a tuple of patterns (while
preserving the single str argument functionality, alas str.endswith), as a
first step for glob.i?glob to accept multiple patterns as well.

Here is the implementation I came up with:

https://github.com/python/cpython/compare/master...andresdelfino:fnmatch-multiple-patterns?expand=1

If this is deemed reasonable, I’ll write tests and documentation updates.

Any opinion?
