How to search for the last occurrence of a regular expression in a string in python?

Question

In python, I can easily search for the first occurrence of a regex within a string like this:

import re
re.search(\"pattern\", \"target_text\")

Answer 1

import re
re.search("pattern(?!.*pattern)", "target_text")

or

import re
re.findall("pattern", "target_text")[-1]

You can use these 2 approaches.

If you want positions use

x="abc abc abc"
print [(i.start(),i.end(),i.group()) for i in re.finditer(r"abc",x)][-1]
