Incomprehensible function!

What does Python do with this Function (list.tik(150)) for indexes?
Is it possible that this function is defined?

As distributed, nothing. The built-in list doesn’t have a tik method. This line would produce an error.

But you could write a class or a module that shadows (hides) the built-in list. I would suggest that is not a great idea, but it would make the line valid.
