Does python has "apply" alike approach like the other languages?

In other languages, you can apply context to function, so you can have the context scope.

The similar thing I couldnt find relative reference for Python.

In below example, if I wana access context scope from outside, what can I do??

On below example, how can I access the class private method from outside function?

Relative example :

class a:
    def __b(S):
        print(11111)

    def c(S):
        d(S)  # how can I apply scope here??

---

def d(S):
    S.__b()


---

a().c()

Thank you very much.

You can bind an unbound function to an object with types.MethodType:

from types import MethodType

class a:
    def b(S):
        print(11111)

    def c(S):
        MethodType(d, S)()

def d(S):
    S.b()

a().c()

This outputs: 11111

It does not, however, let outside functions access "private" methods that are prefixed with double underscores due to name mangling at compilation time.
