Check file or directory exists

You can follow these three ways:

Note1: The os.path.isfile used only for files

import os.pathos.path.isfile(filename) # True if file existsos.path.isfile(dirname) # False if directory exists

Note2: The os.path.exists used for both files and directories

import os.pathos.path.exists(filename) # True if file existsos.path.exists(dirname) #True if directory exists

The pathlib.Path method (included in Python 3+, installable with pip for Python 2)

from pathlib import PathPath(filename).exists()
