You appear to be mixing two ways of doing the same thing.  Either check 
the number of entries in sys.argv or catch the index error, don't do 
both.  Read this, it probably explains things better than I can

Hello List:

I developed a script to walk through a specific directory in my PC
and look for files with the same extension (.shp). I want the user
to enter from MS-DOS and write the the directory, file extension and
csv filename.
My script reads the arguments from Windows console, but when I
opened the txt file and csv file I noticed that isn't walking
through all the root I wrote in MS-DOS. This is my module:

import os, csv, time, socket, sys
from osgeo import ogr,gdal,osr
#This should be the order for the arguments('csv_args.py [root]
[file_extension] [csv filename]')
#The user is typing python csv_args.py C:\ .shp csv.csv

extension = sys.argv[2]

 for root, folders, files in os.walk(directorio):
 file_list.extend(os.path.join(root,fi) for fi in files if
fi.endswith(extension))
