I'm creating pdf file from images but having problem with sorting the jpg files in numeric order I have 20 files from 1.jpg to 20.jpg I'm using below code to sort all files in order 

import os
sorted(os.listdir('path/to/jpg/files'))

but it will print 1.jpg, 11.jpg, 12.jpg and so on.

Any ideas?

    `sorted(os.listdir('path/to/jpg/files'), key=lambda x: int(x.split(".")[0]))` – Rakesh Jul 03 '18 at 12:06

sorted takes a key. You can use lambda function in the key to do a numeric order sort.

Ex:

import os
sorted(os.listdir('path/to/jpg/files'), key=lambda x: int(x.split(".")[0]))
