I think this does what you tried to do with the above code:

import string
filename = raw_input('Enter file : ')
file = open(filename)
line = file.readline()
while line:
	if 0 == string.find(line, 'H3'):	# Does the line start
						# with H3?
		region, district = string.split(line)[-2]
		while ',' == region[-1]:
			region = region[:-1]	# Strip off ','
		print ' Region\t:', region
		print ' District\t:', district
	line = file.readline()

Note that you can't just read from the filename given, you need to call
open() to open the file.
readline() returns one string.  string.split() will split this into
seperate words.

A string.  You will need to manipulate this string with the functions in
the string library to get what you want.
