Sometimes, we want to bind an unbound method with Python.

In this article, we’ll look at how to bind an unbound method with Python.

How to bind an unbound method with Python?

To bind an unbound method with Python, we can use the types.MethodType method.

For instance, we write:

import types


def f(self):
    print(self)


class C:
    pass


meth = types.MethodType(f, C)
meth()

We have the f function that prints the value of self.

Then we set self to C by using types.MethodType(f, C) and assign the returned function to meth.

Therefore, when we call meth, we see:

<class '__main__.C'>

printed.

Conclusion

To bind an unbound method with Python, we can use the types.MethodType method.
