This is in Python

This has two parts. This is a problem on recursion.

Part a:

Write a recursive function that accepts an integer argument, n. The user needs to be asked for the number n. The function should display n lines of asterisks on the screen, with the first (the top) showing 1 asterisk, the second from the top showing two asterisks, up to the nth line which shows n asterisks.

Part b.

Write a recursive function that accepts an integer argument, n. The user needs to be asked for the number n. The function should display n lines of asterisks on the screen, with the first (the top) showing n asterisks, the second from the top showing n-1 asterisks, up to the nth line which shows 1 asterisk.

Submit the two files and two sample outputs for each of the parts.
