(Python) Returning specific values in a string of different format : How do I make python automatically searches a certain specific type of data (e.g date) in a string of different format ?

For example,
For unix values such as -rwxr-xr-x 1 user usergrp 1632 Feb 26 11:03 Desktop/Application, it should return 26 Feb 19

For values such as Desktop/Application,1632,26/02, it should search out for “26/02” and return 26 Feb 19

For values such as 26/02/19 - Desktop/Application - 1632, it should search out for “26/02/19” and return 26 Feb 19

Appreciate all help provided, thank you everyone!
