Answer 1

Addressing Abhisek's comment on Aragon's solution:

import os folder = 'C:'

for root, dirs, files in os.walk(folder):
    for name in files:
        (base, ext) = os.path.splitext(name)
        if ext in "csv":
            print os.path.join(root, name)

Answer 2

you can try this code :

import os
folder = 'C:'

for root, dirs, files in os.walk(folder):
    for name in files:
        print os.path.join(root, name)
    for name in dirs:
        print os.path.join(root, name)

UPDATE:

import os folder = 'C:'

for root, dirs, files in os.walk(folder):
    for name in files:
        nm, ext = os.path.splitext(name)
        if ext == ".csv":
            print os.path.join(root, name)

Answer 3

import os
for (dirpath, dirnames, filenames) in os.walk(directory):
    # Do some processing

That will iterate through the root of the directory specified, for eg. c:/user/name/class/std and enter every folder contained in it, and give you the folders and files contained in them. With that you should be able to do what you need to processing wise.
