Re: Nested loop not working

I am overlooking something stupid.

I have two files: one with keywords and another with data (one record per line).

I want to determine for each keyword which lines in the second file
contains that keyword.

The following code is not working. It loops through the second file
but only uses the first keyword in the first file.

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import re

keywords = open("sleutelwoorde",'r')
data = open("sarua_marine_sleutelwoorde.csv",'r')

remove_quotes = re.compile('"')


for sw in keywords:
for r in data:
swc = remove_quotes('',sw)[:-1]
if swc in r.lower():
print swc + ' ---> ' + r
print swc

What am I missing?

Once you've read all the data from 'data' in the first inner loop, there's no more for the second keyword.

Easiest answer is to do something like:
data.seek(0)
just before the inner loop. That will (re)position to begin of hte 'data' file.
