Python Programming Help

Source Code:

import math
a = float(input('Enter dimension of first side: '))
b = float(input('Enter dimension of second side: '))
c = float(input('Enter dimension of third side: '))

# calculate the semi-perimeter
s = (a + b + c) / 2

# calculate the area
area = (s*(s-a)*(s-b)*(s-c)) ** 0.5
print('The area of the triangle is %0.2f' %area)
