Python – Listing the files in a directory

Language:
Python 2.7

The following example uses functions from the os library to list the files in a given directory:

from os import listdir
from os.path import isfile, join
dir = "D:\\"
files = [f for f in listdir(dir) if isfile(join(dir, f))]
for f in files:
	print join(dir, f)

In the next example the script has been modified to list only files with the name extension ‘jpg’:

from os import listdir
from os.path import isfile, join
dir = "D:\\"
files = [f for f in listdir(dir) if isfile(join(dir, f)) and f[-3:]=='jpg']
for f in files:
	print join(dir, f)

* note that when copying and pasting a script from this example, the indentation may not be pasted correctly.
