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.

The os.scandir() method in Python is used to get an iterator of os.DirEntry objects corresponding to the entries in the directory given by the specified path. 

The entries are yielded in arbitrary order and special entries ‘.’ and ‘..’ are not included. 
 

Syntax: os.scandir(path = ‘.’)
Parameter: 
path: A path-like object representing the file system path. This specify the directory to be scanned. If path is not specified then current working directory is used as path. 
A path-like object is a string or bytes object which represents a path.
Return Type: This method returns an iterator of os.DirEntry objects corresponding to the entries in the given directory. 
 

Code: Use of os.scandir() method 

Python3




# Python program to explain os.scandir() method
 
# importing os module
import os
 
 
# Directory to be scanned
path = '/home/ihritik'
 
# Scan the directory and get
# an iterator of os.DirEntry objects
# corresponding to entries in it
# using os.scandir() method
obj = os.scandir(path)
 
# List all files and directories
# in the specified path
print("Files and Directories in '% s':" % path)
for entry in obj :
    if entry.is_dir() or entry.is_file():
        print(entry.name)
 
 
# entry.is_file() will check
# if entry is a file or not and
# entry.is_dir() method will
# check if entry is a
# directory or not.
 
 
# To Close the iterator and
# free acquired resources
# use scandir.close() method
obj.close()
 
# scandir.close() method is called automatically
# when the iterator is exhausted
# or garbage collected, or
# when an error happens during iterating.

Output: 

Files and Directories in '/home':
