string - How to remove all characters before a specific character in Python?

Question

I'd like to remove all characters before a designated character or set of characters (for example):

intro = "<>I'm Tom."

Now I'd like to remove the <> before I'm (or more specifically, I). Any suggestions?

Answer 1

Use re.sub. Just match all the chars upto I then replace the matched chars with I.

re.sub(r'^.*?I', 'I', stri)
