You don't have to parse through a veritable novel of irrelevant results to find what you're looking for.
They provide example code to show you how to use the method.
They break down the usage more thoroughly than the official docs.
They _show_ you the different parameters you could pass to the method.
Some of them provide interactive REPLs where you can play with and test the method.
The docs break it down _technically_ but they leave questions. Are start/end inclusive? What does it mean to "stop comparing at that position"? Why would you use the start parameter if you're trying to find the end of the string? If you use start does the end parameter count from 0 or from start? What happens if you pass a start or end that are outside the bounds of the string?
Look, I think the Python docs are great and use them all the time. But for the average person looking for info on `endswith` - whether that's someone new trying to understand how it works, or someone experienced looking to understand the parameter types - those pages are more approachable.
