Write a Python Recursive program to calculate the value of 'a' to the power 'b'.

def power(a,b): if b==0: return 1 elif a==0: return 0 elif b==1: return a else: return a*power(a,b-1) print(power(3,4))

power(3,4)=3*power(3,3)

power(3,4)=3*3*power(3,2)

power(3,4)=3*3*3*power(3,1)

power(3,4)=3*3*3*3

power(3,4)=81
