Cannot seem to remove whitespaces from input file?

Question

I'm trying to figure out how to process an input file and print it out without any whitespace present in the output.

My current script looks like this:

#!/usr/bin/python

kf = open ('keyword.txt', 'r')
sl = open ('syslog.txt', 'r')

for line in kf:
    line.replace('\n', "")
    line.strip()
    print line

The output of this however looks like this:

polkitd

anacron

acpid

rt-kit daemon

goa

AptDaemon

AptDaemon.PackageKit

AptDaemon.Worker

python

Does anyone know how to remove the lines of whitespace between each item?

Thank you, being from a C# background I didn't think about this, but this in fact was the problem. — Joanna, Apr 10 '15 at 17:29
shouldnt the code be `line = line.replace('\n', "")`, since the replace function returns a new string — Logan Murphy, Apr 10 '15 at 17:29

Try printing repr(line) instead of print line and see what you get. If there is a '\n', try calling line.strip('\n'). Also, try putting a comma , after print line as such print line,.

both replace and strip return new objects, not change the one you are currently working with so your code should be something like this

line = line.replace(...)
line = line.strip(...)
