Python regex for words with a series of character

Question

I am relatively new to Python regex and have a problem which I could not solve yet.

Problem :

I have strings that contain characters ( | , [ , } , { , \n ) along with alphanumeric characters.

From the following examples, I am trying to extract only frank_one-123_gold.jpg and 45frank_one-123_gold.JPG at the same (as example 1 and 2 may be in the same sentence).

Example1 :

timecrypto|<br>file:_team.svg|[[File:apple.svg]]frank_one-123_gold.jpg

Example2 :

timecrypto|file:_team.svg|[[File:apple.svg_\n\n45frank_one-123_gold.JPG<gallerg/>

Answer 1

You can use "re" lib:

import re

file_name = "_team.svg|[[File:apple.svg]]frank_one-123_gold.jpg"
file_name_filtered = re.split('\]\]|\n',file_name)[-1]

Here we use "\]\]|\n" pattern, where this split the name into the characters "\]\]" or ("or" represented as "|") "\n".
