I would be happy to learn why the for loop is not being executed? Event though a list of WindowsPaths gets printed. Thank you very much in advance.

from pathlib import Path

pathlist = Path("test_data").glob('**/*some_file*.json')
print(list(pathlist))

for path in pathlist:
    print("This never gets printed.")

Because `pathlist` might be empty. – Dec 16 '21 at 18:04

`pathlist` is a generator. You consumed it all when you called `list(pathlist)`, so there's nothing left. – Barmar Dec 16 '21 at 18:04
@Barmar Thank you very much! Sometimes the solution is so simple you don't think of it :) – quest4stack Dec 16 '21 at 18:09
