The following maybe a little better:
        def getExt(fname):
        	return fname.rsplit('.', 1)[1]
                
It uses one method instead of two compared to yours.  And in your code
there's no need for the ‘ext’ variable, you could use:
        def getext(fname):
        	return fname.split('.').pop()

For more information about ‘str’ objects type the following inside the
Python shell:
	>>> help(str)
