How to catch a string based on a subsection of it

Question

I have multiple strings in a list.

Each list is a link in a string format.

I have some strings whose style is the following:

mailto:newsletter.dcda@dcda.com

Some of these strings change in the @ part. They have different addresses.

I want to find a regular expression that can capture the whole text based on the mailto:

part.

Answer 1

Maybe this expression will work

import re

t='mailto:newsletter.dcda@dcda.com'
re.findall('mailto:(?:\w+\.?)+@(?:\w+\.?)+',t)

['mailto:newsletter.dcda@dcda.com']
