i utilize numeric variable regular look part.

what should if want utilize variable in part (?p<hh>\d)

i want output lines contain input number.

using string interpolation:

m = re.compile(r'\d{%d}:\d{%d}' % (var1, var2))

if vars aren't integers may need convert types so:

m = re.compile(r'\d{%d}:\d{%d}' % (int(var1), int(var2)))
