Hi Alfonso,
I see you've had some responses yet -- I've not read them all, and am just
posting the following suggestion you might want to look at:
# read lines with "keys" into a list
selected_keys=open('A.txt', 'r').readlines()
# read all data records into another list
records=open('B.txt', 'r')
Hi,

Dear All,
Sorry it seems that I got the wrong mailing list to subscribe ...
I got the idea that this list was open to newbies ... by the answers I

In that case, what do you use for data of the last key?
If you really have to handle the case where there is a
import os
def pre_process():
if os.path.isfile('revelex.csv'):
os.rename('revelex.csv', 'revelex.tmp')
print "Renamed ok"
else:
print "Exiting, no revelex.csv file available"
exit()
out_file = open('revelex.csv', 'w')
# etc.
if __name__ == '__main__'

You'll already received some sound advice, so I'd just like to point out
that your object will override the built-in object, apologies if
somebody has already said this and I've missed it.

Dear All,
I'm new to Python and started to use it to search text strings in big
(>500Mb) txt files.
I have a list on text file (e.g. A.txt) that I want to use as a key to
search another file (e.g. B.txt), organized in the following way:
A.txt:
Aaa
