What is the shortcut to add multiple fields to a class?

Question

Lets, say that I have a such a class:

class A:
    def __init__(self, x, y, z, ...):

I need a shortcut to add fields given in constructor definition to my model. So after clicking some fancy keys combinations I expect such result:

class A:
    def __init__(self, x, y, z, ...):
        self.x = x
        self.y = y
        self.z = z
        more fields...

What is the workaround to achieve expected result?
