CalcArea | Python Fiddle

#This program takes in a shape and returns an area

shape = input("Please enter a shape: ")

def CalcArea(shape):
    if shape == "rectangle" or shape == "parallelogram":
        width = input("Please enter a width: ")
        height = input("Please enter a height: ")
        area = width * height
    elif shape == "triangle":
        base = input("Please enter a base: ")
        height = input("Please enter a height: ")
        area = 0.5 * base * height
    elif shape == "circle":
        radius = input("Please enter a radius: ")
        area = 3.1415 * (radius ** 2)
    elif shape == "square":
        length = input("Please enter a side length: ")
        area = length ** 2
    elif shape == "ellipse":
        a = input()
        b = input()
        area = 3.1415 * a * b
    elif shape == "trapezoid":
        a = input()
        b = input()
        h = input()
        area = 0.5*(a+b)*h
    else:
        print shape + " is not a valid option.  Please enter another shape."
    return area

area1 = CalcArea(shape)
print(area1)
