title: Python - Check file name for extension
body: <p>Is there a way in Python to check a file name to see if its extension is included in the name?  My current workaround is to simply check if the name contains a . in it, and add an extension if it doesn't...this obviously won't catch files with . but no extension in the name (ie. 12.10.13_file).  Anyone have any ideas?</p>
