Looping issues

[cmmg729]

I am writing a program to compare two different files.

For each line in file1 i want to compare it to all the lines in file2, then go to the next line in file1.

the code i have below is not looping back to the next line in file1, can anyone give me any suggestions to help?

#! /usr/bin/env python

import sys
import fileinput

# Open the two files
f1 = open(sys.argv[1], "r")
f2 = open(sys.argv[2], "r")
for line in f1:
	chrR,chrStart,chrEnd,name,score,strand1,codingStart,codingEnd,itemRbg,blockCount,blockSize,BlockStart = line.strip().split()
	chr = range(int(chrStart), int(chrEnd))	
	lncRNA = set(chr)
	for line in f2:
		chrC,clustStart,clustEnd,annote,score,strand = line.strip().split()
		clust = range(int(clustStart), int(clustEnd))
		cluster = set(clust)
		if strand1 == '-':
			if chrR == chrC:
				if strand1 == strand:
					if lncRNA & cluster:
						print name, annote, 'transcript'
					else:
						continue
				continue
		break

Reset the file object to the beginning with f1.seek(0)
- OR -
Read the first file into a list with file method readlines() and iterate on the list.
