You need something like this:

import string

# Prompt for a filname.
filename = raw_input("Enter filename: ")

# Open the file.
f = open(filename, "r")

while 1:
    line = f.readline()
    if not line:
        break
    line_parts = string.split(line)
    if line_parts[0] == "H3":
        print "Region:\t%s" % line_parts[1]
        print "District:\t%s" % line_parts[2]

f.close()

--S.
