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?
The line:
for r in data
reads through the file until it the end. The next time around the outer
loop it's already at the end of the file. You need to reset it to the
start of the file with:
data.seek(0)
Incidentally, it would be faster if you read the keywords into a list
first (assuming that there isn't a huge number of keywords) and then
scanned through the file once.
