Hi, I want to make it such that the user inputs a file extension and
it prints the number of similar file extensions out.
I tried doing this:

directory = raw_input("input file directory")
ext = raw_input("input file ext")

file_list = len(glob.glob(ext))
print file_list

And my result was this:
which it is suppose to be 11

May I know why? And how do I specify which directory it is searching
the files extension from? I want the user to specify a directory and
it searches the particular directory for the particular file
extensions and prints the number out.
Hope you guys could help.
