Without actually reading your code, if I may, I would suggest using
the os module to confirm that a file exists rather than waiting for an
error to be thrown.

>>> userSuppliedPath = "/this/path/does/not/exist/"
>>> import os.path
>>> if not os.path.isfile( userSuppliedPath ):
	# this has the twofold purpose of:
	# 1) making sure the path exists, and
	# 2) making sure the path is a file
	print "Error!"

	
Error!
