when I print, it says I cannot concatenate float and str. how do I fix this?
shape = input("what shape woul dyou like to choose: circle? triangle? rectangle? or a pentagon?") pie = float(3.141592)
if shape == "circle":
radius = float(input("what is the radius of the circle?"))
area = pie * (radius * radius)
perimeter = radius * pie * 2
print("the area of this circle is " + area)
print(" the circumference of this circle is: " + perimeter)
elif shape == "triangle":
side_1 = float(input("input the value of one of the sides"))
side_2 = float(input("input the value of one of the sides"))
base = float(input("what is the base? "))
tri_perimeter = side_1 + side_2
print("the perimeter of this triangle is " + tri_perimeter)
height = float(input("what is the height? "))
tri_area = (base * height)/2
print("the area of the triangle is " + tri_area)
elif shape == "rectangle":
base = float(input("what is the base? "))
height = float(input("what is the height? "))
rec_area = base * height
rec_perimeter = (base * 2) + (height * 2)
print("the area of the rectangle is " + rec_area)
print("the perimeter is " + rec_perimeter)
else: print("error!")
The part im actually struggling with, is when I want to print something (9area or perimeter). It says that I cannot concatenate str and float. How do I fix?
