Testing for the existence of files or directories with os.path

The os module has functions to test for the existence of files and directories which can be used as follows.

import os


os.path.exists('/foo/bar')	# returns True or False

# Test what kind of file it is
os.path.isfile('/foo/bar')	# True or False
os.path.isdir('/foo/bar')	# True or False

You can also retrieve metadata about the file in question.

import time


os.path.getsize('/foo/bar')		# Returns size in int

# Get last modified time as timestamp, convert to time object
time.ctime(os.path.getmtime('/foo/bar'))
