Dir Command In Python REPL

The aim of this explainer💡 is to demonstrate how to use dir in python, i.e. how to navigate through the file structure within REPL/Code.

1. steps

• import os
• from pprint import pprint as pp
• pp(next(os.walk("."))) to return contents of the current workind directory
• for only files pp(next(os.walk(".")[2]))
• for only folders pp(next(os.walk(".")[1]))
• for only path pp(next(os.walk(".")[0]))

2. explanation

• os.walk(directory) returns a generator that yields a 3-tuple with:
• dirName
• list of subdirs
• list of files
• to evaluate (get results immediatelly), nest it into the next()
