Python | os.path.normcase() method

Last Updated : 09 Mar, 2022

OS module in Python provides functions for interacting with the operating system. OS comes under Python’s standard utility modules. This module provides a portable way of using operating system dependent functionality. os.path module is sub module of OS module in Python used for common path name manipulation.
os.path.normcase() method in Python is used to normalize the case of specified path name. On windows, this method converts all characters in the specified path to the lowercase and forward slash ('/') to backslash ('\'). This method returns the specified path unchanged on operating systems other than Windows.

Syntax: os.path.normcase(path)
Parameter:
path: A path-like object representing a file system path.
Return Type: This method returns a string value which represents the normalized case in the specified path.

Code #1: Use of os.path.normcase() method (On Windows)

Python3

# Python program to explain os.path.normcase() method 
  
# importing os.path module 
import os.path

# Path
path = r'C:\User\admin\Documents'


# Normalize the case of  
# characters in the specified path
norm_path = os.path.normcase(path)

# Print the normalized path  
print(norm_path)

# Path
path = '/hoMe/UseR/'


# Normalize the case of  
# characters in the specified path
norm_path = os.path.normcase(path)

# Print the normalized path  
print(norm_path)

# Path
path = r'C:\Users/Desktop'

# Normalize the case of  
# characters in the specified path
norm_path = os.path.normcase(path)

# Print the normalized path  
print(norm_path)

Output:

c:\\user\\admin\\documents
\\home\\user
c:\\users\\desktop

Code #2: Use of os.path.normcase() method (On operating systems other than Windows)

Python3

# Python program to explain os.path.normcase() method 
  
# importing os.path module 
import os.path

# Path
path = '/home/UseR/Documents'


# Normalize the case of  
# characters in the specified path
norm_path = os.path.normcase(path)

# Print the normalized path  
print(norm_path)

# Path
path = '/hoMe/UseR/'


# Normalize the case of  
# characters in the specified path
norm_path = os.path.normcase(path)

# Print the normalized path  
print(norm_path)

# os.path.norcase() method will return
# the specified path as it as
# on operating systems 
# other than Windows
