Not having to rewrite 'obj.' on each line

[beuaaa]

Let's say I have this class:

class MyNewClass:
    def func1(self):
		print('something to do')
    def func2(self):
		print('other thin to do')

The normal syntax to call methods of this class is:

obj = MyNewClass()
obj.func1()
obj.func2()

I would like to do exactly the same thing but without having to rewrite 'obj.' on each line as in this imaginary syntax:

obj = MyNewClass()
using obj:
    func1()
    func2()

Does Python allow you to write this kind of code?

No. Even using a context manager, you'd just be substituting. Obviously you could create a function that could take a class/instance and call methods for that. Examples on SO.

Are you trying to save on typing?

You can do something terrible like this

from copy import copy

class Greeter:
    def __init__(self, to):
        self.to = to

    def hello(self):
        return "Hello, {}!".format(to)

class Magic:
    def __init__(self, instance, enclosing_locals):
        self.instance = instance
        self.enclosing_locals = enclosing_locals
        self.origin_enclosing_locals = copy(enclosing_locals)

    def __enter__(self):
        for key in dir(self.instance):
            self.enclosing_locals[key] = getattr(self.instance, key)

    def __exit__(self, type, value, traceback):
        for key in list(self.enclosing_locals.keys()):
            del self.enclosing_locals[key]

        self.enclosing_locals.update(self.origin_enclosing_locals)

with Magic(Greeter("world"), locals()):
    print(hello())

I bet there's a way to not require the locals() call but I couldn't figure it out in a few minutes' Googling. Note that I'm messing with scopes such that any new variables defined within the with-block which would normally be available after the block, won't be. Anyone familiar with Python reading your code would be confused unnecessarily.

you can also keep you class in a separate file, then if there's a method that you use a lot, import like:
from class import method.
now you can use method by itself, without the class name.

That's a good idea. I believe that's how some stateful functions work in the random module. That said, you'd be limiting yourself to singletons (or plural-tons, but a fixed set of them). If that sufficed, I'd say it's an order of magnitude less terrible than what I posted.
