Pyramid of asterisks program in Python

Question

I've written a program in C++ that displays a pyramid of asterisk (see below) and now I'd like to see how it's done in Python but it's not as easy as I'd thought it would be.

Has anyone tried this and if so could you show me code that would help out?

Thanks in advance.
