How to create class class object and function class object in python

Question

in java we can have objects of class and Method. how we can achieve same in python.

Example (in java) """Class cls=Class.forName("Test.class"); Method method = Test.class.getMethods()[];"""

There are reflection functions such as type(), dir(), isintstance(), callable(), getattr(), setattr() and others. But there is no such Java'ic thing like class of class, because everything in python is an object (even classes) — sudden_appearance

look at meta programming I think. what do you mean by function class object — Narcisse DOUDIEU SIEWE

You can create the class by reflection.

And with inspect built-in module, you can get methods:

import inspect


class MyClass:
    def __init__(self):
        self.a = "default"

    def method_1(self):
        pass


my_second_way_to_call_class = globals()["MyClass"] #reflection
my_third_way_to_call_class = MyClass # assignation of the object def

instance_1 = MyClass()
instance_2 = my_second_way_to_call_class()
instance_3 = my_third_way_to_call_class()

method_list = inspect.getmembers(instance_1, predicate=inspect.ismethod)
print(method_list)
