folder include files as below:
Check_noise#3_P020_20211220_094542_CAMEMSNIOSAI31_2D.csv
Check_noise#3_P020_20211220_100122_CAMEMSNIOSAI31_2D.csv
check noise_P020_20220504_085928_CAMEMSNIOSAI11_2D.csv
check noise_P020_20220504_131424_CAMEMSNIOSAI11_2D.csv
te_noise_P020_20220713_170832_CAMEMSNIOSAI21_2D.csv
noise_P020_20220802_153723_CAMEMSNIOSAI21_2D.csv
noise_P020_20220803_085104_CAMEMSNIOSAI31_2D.csv
noise_P020_20221226_153635_CAMEMSNIOSAI11_2D.csv
gyl_P020_20230214_102731_CAMEMSNIOSAI41_2D.csv
gyl_Noise_P020_20230214_144514_CAMEMSNIOSAI41_2D.csv

can you share me a good way to do that,thanks!

import re
from pathlib import Path
basepath = Path(r'C:\Eng\CSV')
pattern = '.*(gyl|noise)'
matching_files = []

for _path in [p for p in basepath.rglob('*.csv')]:
    if re.match(pattern, _path.name):
        matching_files.append(_path)
        print(_path.name)

You don't want .* at the start of your pattern. "noise|gyl" should work fine.
