instance method

class MyClass:
    def __init__(self, x, y):
        self.x = x
        self.y = y

    def sum(self):
        return self.x + self.y

In this example, sum() is an instance method of the MyClass class. It takes the instance itself (self) as the first argument, and returns the sum of x and y. To call this method, we first need to create an instance of the class, and then use the dot notation to call the method on that instance:

obj = MyClass(3, 5)
print(obj.sum())  # Output: 8
