I don't think the OP realized how to apply that solution to all directories @tzaman – rassa45 Oct 30 '15 at 03:19

You can use the os.walk method. Here is an example:
# !/usr/bin/python
import os
for root, dirs, files in os.walk(".", topdown=False):
for name in files:
print(os.path.join(root, name))
for name in dirs:
print(os.path.join(root, name))
copied from http://www.tutorialspoint.com/python/os_walk.htm
See the full documentation: https://docs.python.org/2/library/os.html#os.walk

Thanks for replying @swoogan. I want to find each and every files of the computer not just a current working directory. – Rohan Dongre Oct 30 '15 at 18:55

@RohanDongre that is exactly what `os.walk` does. Please refer to the documentation I linked: "Generate the file names in a directory tree by walking the tree either top-down or bottom-up" – Swoogan Oct 31 '15 at 03:09

Refer to the os module.
os.chdir(path) changes the working dir.
os.listdir() lists all the directories in your working dir.
If you wanna find all the directories of your current system, you need to iterate through your system using for example BFS search (https://en.wikipedia.org/wiki/Breadth-first_search).
