I think I need to use regex here. Perhaps you will agree.
Input file:
1119|Avail|53|Potato Chips
1234|Avail|53|Potato Chips and salse
1399|Avail|53|potato chips
1445|Avail|
I have a pipe delimited text file with 5 columns which looks like this:
12345|some text|some more text|example125 oo3 3456|example32423
11223|more text|and more|example/73d 77665|example455667
12677|text|more|anotherexample 123|anotherexample45
What I want to output is:
12345|some text|some more t
I got it. I was comparing '345' to '345\n'
Adding the '\n' to the slice did indeed do the trick.
#!/usr/bin/env python

infile = open("filex")
outfile = open("results_testx", "w")
zips = open("zippys", "r")
match_zips = zips.readlines()

OK - you handled the problem regarding reading to end-of-file. Yes it
takes a lot longer, because now you are actually iterating through
match_zips for each line.
How large are these files? Consider creating a set from match_zips. As
lists get longer, set membership test become faster than list
I'd suggest reading the data from the match_zips into a list, and if
the format isn't correct, doing some post-processing on it. But
there's no way to advise on that since we weren't given the format
of either file.
zipdata = match_zips.readlines()
Then you can do an if XXX in zipdata
ank. Any suggestions?

# Find records that match zipcodes in zips.txt

Sorry - my mistake - try:
infile = open("filex")
match_zips = open("zippys")
result = [line for line in infile if line in match_zips]
print result
okThanks...This should do it:
#!/usr/bin/env python
infile = open("filex")
zips = open("zippys")
match_zips = zips.readlines()
results = [lin
I wrote a script that compares two text files (one zip code file, and
one address file) and tries to output records that match the
zipcodes. Here is what I have so far:
#!/usr/bin/env python
# Find records that match zipcodes in zips.txt
def main():
infile = open("/Users/tgw/NM
