Better ways to create a directory in python

When you're creating a new directory in python, it's better to check if that directory exists first, in case your code run into error.

Example 1

• use os.path.exists() to check if the directory's existence
• then create a directory with os.mkdir() only if it does not exist

import os
path_to_dir = '/content/test'
if not os.path.exists(path_to_dir):
  os.mkdir(path_to_dir)

Example 2

• use a try-except block to handle error

import os
path_to_dir = '/content/test'
try: 
    os.mkdir(path_to_dir ) 
except OSError as error: 
    print(error)

[Errno 17] File exists: '/content/test'

Example 3

• use os.mkdirs() when there is any non-existent directory in your path
• for instance, you want to create a directory in called /test2 in directory /test1, however directory /test1 is missing.

import os
path_to_dir = '/content/test1/test2/'
try: 
    os.mkdir(path_to_dir ) 
except OSError as error: 
    print(error)
