Answer 1

The easiest way would be to filter the glob results yourself. Here is how to do it using a simple loop comprehension:

import glob
res = [f for f in glob.glob("*.txt") if "abc" in f or "123" in f or "a1b" in f]
for f in res:
    print f

You could also use a regexp and no glob:

import os
import re
res = [f for f in os.listdir(path) if re.search(r'(abc|123|a1b).*\.txt$', f)]
for f in res:
    print f

(By the way, naming a variable list is a bad idea since list is a Python type...)
