Python recursion problem

def printTriangleBottom(m, i):

3. Write a recursive function printTriangleBottom() that takes two integers as parameters and prints a triangle of asterisks based on those parameters. The first integer represents the maximum number of asterisks to be printed in the bottom row of the triangle pattern seen in the examples below. The second integer represents the indentation used for the first line of the pattern. If the first parameter is negative or zero, nothing will be printed. You are allowed to assume that the second parameter will be non-negative. You are allowed to use string multiplication (e.g. c*n for a character c and an integer n) and concatenations, but no other string functions are allowed. The following shows several sample runs of the function: >>> printTriangleBottom(6,5) ** **** ****** >>> printTriangleBottom(6,0) ** **** ****** >>> print TriangleBottom(7,7) *** ***** ******* >>> printTriangleBottom(4,3) ** **** >>> printTriangleBottom(0,0)
