Python Program to Calculate Simple Interest

Calculate Simple Interest Python Program

This python program is used to compute simple interest for the user inputs principle, years and rate.

# Compute simple interest for the user inputs p, n and r
#!/usr/bin/python

def calculate_simple_interest(p, n, r):
    si = 0.0
    si = float(p*n*r)/float(100);
    return si;

if __name__ == '__main__':
    p = float(input("Enter values\np: "));
    n = int(input("n: "));
    r = float(input("r: "));
    simple_interest = calculate_simple_interest(p, n, r);
    print("Simple interest value: %.2f" % simple_interest);

$ python simple_interest.py 
Enter values
p: 100000
n: 3
r: 10.5
Simple interest value: 31500.00

Print Simple Interest using format method
