The end of the file is signalled by an empty string, and a blank line with
the trailing "\n" stripped off is an empty string, too. Therefore you have
to perform the line == '' test before the stripping.
Here's an alternative approach:
for line in f:
line = line.rstrip()
if line:
print line
This will ignore any lines containing only whitespace and remove trailing
whitespace from the non-white lines.
