Problem of the Day
A new programming or logic puzzle every Mon-Fri

Directory Listing

Welcome back to another awesome Monday!

We'll start the week off with a simple one. Today's problem is to create a program that takes in a directory on your computer and outputs the files and folders in that directory. Bonus points for differentiating between files and folders in your output.

    #python 2.7
import os

for dirname, dirnames, filenames in os.walk('.'):
    # print path to all subdirectories first.
    for subdirname in dirnames:
        print "<Dir> \t" + os.path.join(dirname, subdirname) 

    # print path to all filenames.
    for filename in filenames:
        print "<File> \t" + os.path.join(dirname, filename)
