[FIXED] glob.glob from multiple paths

Issue

I have the following code

os.chdir("X:\data1")
for file in glob.glob("*.pdf"):

to find all the .pdf files in X:\data1\ directory

I would like to also find all the .txt file in Y:\data2\ directory

I have this snippet in multiple places in the source code, so I would like to make only a little change.

Solution

Would something like this do?

import os
import glob


def ignore_case(pattern):
    return ''.join((f'[{c.lower()}{c.upper()}]' if c.isalpha() else c for c in pattern))


def multi_glob(patterns):
    for path, pattern in patterns:
        yield from glob.iglob(os.path.join(path, ignore_case(pattern)))


list(multi_glob((("X:\data1", "*.pdf"), ("Y:\data2", "*.txt"))))

---

Essentially, instead of os.chdir(path); glob.glob(pattern) you could just do glob.glob(os.path.join(path, pattern)). If you you want this to happen for multiple path/pattern combinations, you could just have a loop through them. Finally, to get case insensitive patterns, just replace each letter c of the pattern with [cC].
