Explanation / Answer

A UML class diagram

describes the attributes and methods of one or more classes

=============================================================================Consider the following code:

class Multiplier:
    def __init__(self):
        self.num1 = 0
        self.num2 = 0

    def getProduct(self):
        return self.num1 * self.num2

def main():
    m = Multiplier()
    m.num1 = 7
    m.num2 = 3
    print(m.num1, "X", m.num2, "=", m.getProduct())

if __name__ == "__main__":
    main()

What is (are) the methods of the class?

getProduct()

__init__()

=============================================================================

Consider the following code:

class Rectangle:
    def __init__(self, height, width):
        self.height = height
        self.width = width

    def getPerimeter(self):
        perimeter = self.height * 2 + self.width * 2
        return perimeter

    def getArea(self):
        area = self.height * self.width
        return area

    def getStr(self):
        return str(self.height) + " by " + str(self.width)

How many public attributes does this class define?

2 height and weight

        self.__value = random.randrange(1, 7)

ans:print(die.__value)

===================================================

Consider the following code:

class Multiplier:

def main():
    m = Multiplier()
    m.num1 = 7
    m.num2 = 3
    print(m.num1, "X", m.num2, "=", m.getProduct())

if __name__ == "__main__":
    main()

ans:num1,num2
