How to iterate through images in a folder Python?

Last Updated : 21 Jul, 2022

In this article, we will learn how to iterate through images in a folder in Python.

Method 1: Using os.listdir

Example 1: Iterating through .png only

At first we imported the os module to interact with the operating system.
Then we import listdir() function from os to get access to the folders given in quotes.
Then with the help of os.listdir() function, we iterate through the images and printed the names in order.
Here we have mentioned only .png files to be loaded using the endswith() function.

Python3

# import the modules
import os
from os import listdir

# get the path/directory
folder_dir = "C:/Users/RIJUSHREE/Desktop/Gfg images"
for images in os.listdir(folder_dir):

    # check if the image ends with png
    if (images.endswith(".png")):
        print(images)

Output:

Example 2: Iterating through all kinds of images

Here we have mentioned .png, .jpg, .jpeg files to be loaded using the endswith() function.

Python3

# import the modules
import os
from os import listdir

# get the path or directory
folder_dir = "C:/Users/RIJUSHREE/Desktop/Gfg images"
for images in os.listdir(folder_dir):

    # check if the image ends with png or jpg or jpeg
    if (images.endswith(".png") or images.endswith(".jpg")\
        or images.endswith(".jpeg")):
        # display
        print(images)

Output:

Method 2: Using pathlib module

At first, we imported the pathlib module from Path.
Then we pass the directory/folder inside Path() function and used it .glob('*.png') function to iterate through all the images present in this folder.

Python3

# import required module
from pathlib import Path

# get the path/directory
folder_dir = 'Gfg images'

# iterate over files in
# that directory
images = Path(folder_dir).glob('*.png')
for image in images:
    print(image)

Output:

Method 3: Using glob.iglob()
