Filename casing changed to lower when argument for Python Glob module is taken from list

I have Python list with filenames ("filename_mask_list"), and I need to search some root Directory and its Sub-directories to find files, which match my filenames, in order to copy them to some common directory.

I have used pathlib.Path.glob to serach recursively directories:

from pathlib import Path
filename_mask_list = ['DEU.FourSeasonsHotelsandResorts.csv', 'DEU.Hilton.csv', 'DEU.Hertz.csv']
for searched_file in filename_mask_list:
    for searched_path in Path('C:\root_dir').glob('**/' + searched_file):
        print(searched_path)

With above code, the found filename in printed "searched_path" is in lower case. If I use direct option to instead of passing element from list as search criteria the casing is preserved:

for searched_path in Path('C:\root_dir').glob('**/DEU*.csv'):
    print(searched_path)

I need to preserve filename casing of copied files, because having it in lowercase will cause dependent processes to crash.

Using glob.glob will give you the file names with the same case as in the search criteria. I don't know the reasons for this apparent inconsistency.

import glob
filename_mask_list = ['DEU.FourSeasonsHotelsandResorts.csv', 'DEU.Hilton.csv', 'DEU.Hertz.csv']
for searched_file in filename_mask_list:
    for searched_path in glob.glob('C:\root_dir/**/' + searched_file, recursive=True):
        print(Path(searched_path))

Note that I preserved your spelling 'C:\root_dir' for clarity but it is most lilely wrong.
