  1. This script sucks

  2. The variables names are misspelled (i.e. "similair")

  3. A glob.glob() call to the regex module is failing because it's not sanitizing the filenames. Wrap it in a try/catch and print a warning and then continue on if that's what you want.

oh my. clean up the formatting. please.

You have a problem in the regular expression you are passing to glob.

The reason is the file name, which you printed in "Looking for ...", contains characters which are non-literal in regular expressions, i.e. they are special characters in regular expressions. You need to escape these characters so the re compiler does not tread them as special.

Glob doesn't take regular expressions. It has only three kinds of simple matching operators. To escape characters, you enclose them individually in [square brackets].

glob.escape() will handle it for you.
