import math

p=float(input("Enter the Principle Amount : "))

r=float(input("Enter the Rate : "))

t=float(input("Enter the rate : "))
amt=p*(math.pow((1+r/100),t))
ci=amt-p

print("Compound Interest is : ",ci)

Output:-

Enter the Principle Amount : 8000

Enter the Rate : 4.5

Enter the rate : 3

Compound Interest is :  1129.328999999998
