Running the "ls" (list) command in Python for a specific directory

ls-example2.py

# Demo of using the ls command in Python
# I have another one here: https://gist.github.com/keithweaver/f77c5001e6e38b7c8fa5a4fb1505bc73
# But I really didn't want it to be the current path. I want to pass the path
# in. I found this example of listing all files in a path from SO:
# https://stackoverflow.com/questions/3207219/how-do-i-list-all-files-of-a-directory
# Works perfect.
from os import listdir
from os.path import isfile, join

mypath = '../';

onlyfiles = [f for f in listdir(mypath) if isfile(join(mypath, f))]

print onlyfiles
# Returns a list of strings.
