If you're on Linux, why not just use grep?
$ grep -v theword output.pdb
Otherwise, just replace "if line:" with "if 'theword' not in line:".
Thanks to rstrip and print, the script changes the file's line endings
to the platform's default one. "rstrip()" also removes other types of
whitespace, like spaces and tabs.
I'm not sure how that script handles different line endings in the file.
Might want to use 'rb' instead of 'r' to open the file in binary mode on
Windows (to also help with other issues), or 'rU' or 'rbU' to use
Python's universal newline mode.)
