python print all files which contain specific word in it

[snippsat]

As mention pathlib is a better choice,for search a word i would prefer regex rather than glob.
pathlib has own glob Path.glob.
To give a example with regex as mention,this search for word life in filename.

from pathlib import Path
import re

my_dir = r'C:\code\a_folder'
pattern = re.compile(r'life')
for file in Path(my_dir).iterdir():
    if file.is_file:
        if re.search(pattern, file.stem):
            print(file)

Output:
C:\code\a_folder\life.py
C:\code\a_folder\life.txt
C:\code\a_folder\life_Kopi.py
C:\code\a_folder\meaninglife.py

Also see that pathlih always give full path back,then do not need too use join() to get full path.
A stricter search can eg add \b to do a whole words only search.

pattern = re.compile(r'\blife\b')

Output:
C:\code\a_folder\life.py
C:\code\a_folder\life.txt
