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.isdir() method in Python is used to check whether the specified path is an existing directory or not. This method follows symbolic link, that means if the specified path is a symbolic link pointing to a directory then the method will return True.
Syntax: os.path.isdir(path) Parameter: path: A path-like object representing a file system path. Return Type: This method returns a Boolean value of class bool. This method returns True if specified path is an existing directory, otherwise returns False.
Code #1: Use of os.path.isdir() method
# Python program to explain os.path.isdir() method 
    
# importing os.path module 
import os.path
  
# Path
path = '/home/User/Documents/file.txt'
  
# Check whether the 
# specified path is an
# existing directory or not
isdir = os.path.isdir(path)
print(isdir)
  
  
# Path
path = '/home/User/Documents/'
  
# Check whether the 
# specified path is an
# existing directory or not
isdir = os.path.isdir(path)
print(isdir)

                    
Output:
False
True
Code #2: If the specified path is a symbolic link
# Python program to explain os.path.isdir() method 
    
# importing os.path module 
import os.path
  
  
# Create a directory
# (in current working directory)
dirname = "GeeksForGeeks"
os.mkdir(dirname)
  
# Create a symbolic link
# pointing to above directory
symlink_path = "/home/User/Desktop/gfg"
os.symlink(dirname, symlink_path)
  
  
path = dirname
  
# Now, Check whether the 
# specified path is an
# existing directory or not
isdir = os.path.isdir(path)
print(isdir)
  
path = symlink_path
  
# Check whether the 
# specified path (which is a
# symbolic link ) is an
# existing directory or not
isdir = os.path.isdir(path)
print(isdir)

                    
Output:
True
True
