Python regex to replace characters in the middle of url

I need to replace ‘AUTO’ with ‘ALL’. Can anyone help with a regex to do that?

‘https://eur-lex.europa.eu/legal-content/AUTO/?uri=CELEX:52022DC0085’

needs to become the below string:

‘https://eur-lex.europa.eu/legal-content/ALL/?uri=CELEX:52022DC0085’

>Solution :

You don’t necessarily need to use regex in this case. Here are some ideas that should get you your desired result:

Using string replace method:

u=url.replace('AUTO', 'ALL')

Using re module with string method:

import re
u=url.replace(re.search(r'AUTO', url)[0], 'ALL')
