How do I find the first of a few characters in a string in python. : How do I find the first of a few characters in a string in python? I have used find() and index() but they find only one character. How do I find the first position of a single character out of the few characters I want to be searched for?

So I want to find the position of the first operator(out of the 4 arithmetic operators) in an inputted string else it should return -1. 


Sorry if this is a very stupid question but I have been searching and trying out multiple options over the past few days. I am also a beginner in python.
