Find files in a directory with a partial string match

Having the files in /mydir as follows

mydir
├── apple1.json.gz
├── apple2.json.gz
├── banana1.json.gz
├── melon1.json.gz
└── melon2.json.gz

you could either do

import glob
import os

os.chdir('/mydir')
for file in glob.glob('apple*.json.gz'):
    print file

or

import glob

for file in glob.glob('/mydir/apple*.json.gz'):
    print file

Changing directories will not effect glob.glob('/absolute/path').

Double List Comprehension Method

I was looking for a similar tool and developed a double list comprehension method that should work well for your case (I tested it for my case) ...

import os

def get_file_names_with_strings(str_list):
    full_list = os.listdir("path_to_your_dir")
    final_list = [nm for ps in str_list for nm in full_list if ps in nm]

    return final_list


print(get_file_names_with_strings(['apple', 'banana', 'melon']))
