Make a function inside of another function-CodePudding

I was wondering if you can make a function inside of another function in python. Just like this:

f().f2()

The f() is the first function, and f2() is the second function. Say f().f2() prints out "Hello world". But if I change the .f2() to .f3() it will print another string of text.

Is it possible?

Here's one approach:

def f():
    class F:
        @staticmethod
        def f2():
            print("Hello world")

        @staticmethod
        def f3():
            print("Another string of text")
    return F


f().f2()
f().f3()

    def f():
    class F:
        @staticmethod
        def f_2():
            print("something")

        @staticmethod
        def f_3():
            print("something 2")
    return F


f().f_2()
f().f_3()

I like Samwise answer better, but here's a way of doing it without classes, if you really wanted to:

def f():
    def f2():
        print("Hello world")

    def f3():
        print("Another string of text")

    for func_name, func in locals().items():
        setattr(f, func_name, func)

    return f


f().f2()
f().f3()
