One formatting detail: there is a blank line after each line
printed, how do I ged rid of the extra blank lines?
lines = [line.strip() for line in infile if line[146:148] not in
omit_states]
print '\n'.join(lines)
This approach stripped leading blank spaces introducing errors into my
fixed width file.
or alternatively
lines = [line for line in infile if line[146:148] not in omit_states]
print ''.join(lines)
This works beautifully leaving leading blank spaces intact. Thanks.
Just remember that doing a list comprehension like that on a large
file will drastically reduce the speed of your application as well
as introduce memory bloat.
Processing a file with well over 1 million records worked very
quickly, several seconds. Did not notice excessive memory bloat. I do
have 2 gigs of ram on my Macbook Pro however.
