Python: Rename all files in a folder with names as numbers in ascending order

Hi Friends,

This script will rename files as 1.zip, 2.zip, 3.xls etc for all files in same folder as scripts:

import os
x = 0
for filename in os.listdir(os.path.dirname(os.path.abspath(__file__))):
    ext = filename.split('.')
    extension = ext[1]
    os.rename(filename, str(x) + '.' + extension)
    x = x + 1

=====================================================================

Explanation:

1. extension = ext[1] collects the extension of file. If you skip this line, the files will be renamed without any extension.

2. Script should be in same folder as files. There should not be any folder in the folder.
