python: split string after a character

Question

I have a string with two "-"

467.2-123-hdxdlfow

I want to remove everything after the second "-" so that I get "467.2-123". What is the best way to do this?

Answer 1

before, sep, after = theString.rpartition("-")

This splits the str about the last occurrence of "-" and your answer would be the variable before.
