Python Glob doesn't recognize file pattern with arbitary numbers 2 to 12 in a path string

Question

Is there a way to get an OR condition inside the file path for glob to recognize it? something like source_path = path + ('[1-9]+'|'[1-9][0-1]+'), mainly to recognize file with filename as (just an exaample):

filename_2, 
filename_3, 
filename_10, 
filename_11,

import glob 
source_path = path + '[1-11]*'
for file in gb.glob(source_path): 
    print('file=', file) #'--gives no output

source_path = path + '[1-9]*'
for file in glob.glob(source_path):
    print('file=', file)

This code only detects filename_2 and filename_3.

Answer 1

Number of items to match the file name : 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11 something like this works:

0[1-9]|1[0-1]
