How to find unqiue file extensions in python pandas dataframe, series?-CodePudding

I have a csv file that contains hundreds of images path and text file path with different extensions. Now i want to find the unique extension of these images and text files. How do i do that? eg of data contained in csv file:

images_path:

https://img.sportstars.id/2021/07/h4bc44/master_B7Nrz3845M_1077.JPG

https://img.sportstars.id/2021/07/j6KY90/master_9uYf5T2Y97_1940.jpg

text_path:

xNeW1g.txt
YnENun.txt
tstaxy.txt

Note: both text and image path are contained in same csv as column names. Please any help would be appreciated. Thanks

Use @tzinie's solution:

df['images_extensions'] = df['images_path'].apply(lambda x: os.path.splitext(x)[-1])
