Q1)Write a program to calculate compound interest when principal, rate and number of
periods are
given.
SOL)
def compound_interest(principal, rate, time):
amount = principal * (1 + rate/100)**time
return amount - principal
# Example
p = float(input("Enter Principal: "))
r = float(input("Enter Rate: "))
t = int(input("Enter Time Period: "))
ci = compound_interest(p, r, t)
print(f"Compound Interest: {ci:.2f}")
OUTPUT:-
Enter Principal amount: 10000
Enter Rate of Interest: 5
Enter Time Period (in years): 2
