[FIXED] TypeError: missing 1 required positional argument in call to super.__init__()

Issue

I'm writing a program to find the volume of a cylinder using inheritance. However, I'm getting the following error, and I'm not sure how to resolve it:

TypeError: __init__() missing 1 required positional argument: 'height'

Here is my code:

class Circle:
    def __init__(self,radius,height):
        self.radius = radius
        self.height = height
    
class Cylinder(Circle):
    def __init__(self,radius,height):
        super().__init__(radius, height)
        self.volume = 3.14 * (self.radius ** 2) * self.height
   def set_volume(self):
        print(self.volume)
    
radius = float(input("radius:"))
height = float(input("height:"))
cyl = Cylinder(radius,height)
print("Cylinder volume:", cyl.set.volume())

Solution

Your call to the __init__ of the superclass isn't correct. You need to pass in the radius and height parameters explicitly, rather than passing in the name of the superclass.

super().__init__(Circle)

should be

super().__init__(radius, height)
