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 modulesimport osfrom os import listdir# get the path/directoryfolder_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 modulesimport osfrom os import listdir# get the path or directoryfolder_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 modulefrom pathlib import Path# get the path/directoryfolder_dir = 'Gfg images'# iterate over files in# that directoryimages = Path(folder_dir).glob('*.png')for image in images: print(image) |
Output:
Method 3: Using glob.iglob()
- At first we imported the glob module.
- Then with the help of glob.iglob() function we iterate through the images and print the names in order.
- Here we have mentioned .png files to be loaded using the endswith() function.
Python3
# import required moduleimport glob# get the path/directoryfolder_dir = 'Gfg images'# iterate over files in# that directoryfor images in glob.iglob(f'{folder_dir}/*'): # check if the image ends with png if (images.endswith(".png")): print(images) |
Output:
