Call Class Method From Another Class

Question

In Python, is there a way to call a class method from another class? I am attempting to spin my own MVC framework in Python and I can not figure out how to invoke a method f

class CurrentValue:

    def __init__(self, value):
        self.value = value

    def set_val(self, k):
        self.value = k

    def get_val(self):
        return self.value


class AddValue:

    def av(self, ocv):
        print('Before:', ocv.get_val())
        num = int(input('Enter number to add : '))
        nnum = num + ocv.get_val()
        ocv.set_val(nnum)
        print('After add :', ocv.get_val())


cvo = CurrentValue(5)

avo = AddValue()

avo.av(cvo)

We define 2 classes, CurrentValue and AddValue We define 3 methods in the first class One init in order to give to the instance variable self.value an initial value A set_val method where we set the self.value to a k A get_val method where we get the valuue of self.value We define one method in the second class A av method where we pass as parameter(ovc) an object of the first class We create an instance (cvo) of the first class We create an instance (avo) of the second class We call the method avo.av(cvo) of the second class and pass as an argument the object we have already created from the first class. So by this way I would like to show how it is possible to call a method of a class from another class.

I am sorry for any inconvenience. This will not happen again.

Before: 5

Enter number to add : 14

After add : 19
