How to define a member function outside class in python?

Question

import numpy as np

class MyClass:

        a = int()
        b = float()
        c = np.array([0 for i in range 10])

        def Memberfunction():

            print("Hii")

For such code how can I define the member function outside the class? Thank you in advance — Prateek Sarangi, Jun 10 '18 at 13:23
I have defined the member function MemberFunction inside the class MyClass, how can I do it outside the class as we do it in C++, like class MyClass{ int MemberFunction(); } int MyClass::MemberFunction(){ cout<<"HII"; } How to write such code in python? — Prateek Sarangi, Jun 10 '18 at 13:27

class test_class():
    def __init__(self, some_func):
        self.some_value = 2    
        setattr(type(self), some_func.__name__, some_func)

def my_requested_func(self):
    print(self.some_value)

class_instance = test_class(my_requested_func)
class_instance.my_requested_func()

This should work, but I dont see any reason for you wanting to do this.
