Python: Find a substring in a string and returning the index of the substring

by

There’s a builtin method find on string objects.

s = "Happy Birthday"
s2 = "py"

print(s.find(s2))

Python is a “batteries included language” there’s code written to do most of what you want already (whatever you want).. unless this is homework 🙂

find returns -1 if the string cannot be found.
