Introduction
In Python, it is often necessary to find the index of the first element in a list that satisfies a certain condition. This can be achieved using a list comprehension, enumerate(), and next(). In this challenge, you will be tasked with writing a function that finds the index of the first element in a list that satisfies a given testing function.
