对于python中的每个类中的函数

class ExampleClass:
    def __init__(self, arg1, arg2):
        self.arg1 = arg1
        self.arg2 = arg2

    def function1(self, arg3):
        self.arg3 = arg3

    def function2(self):
        return self.arg1 + self.arg2

    def function3(self, arg4):
        self.arg4 = arg4

class AnotherClass:
    def __init__(self, arg1, arg2):
        self.arg1 = arg1
        self.arg2 = arg2

    def function1(self, arg3):
        self.arg3 = arg3

    def function2(self):
        return self.arg1 + self.arg2

    def function3(self, arg4):
        self.arg4 = arg4
