Shorthand for defining Python functions that are the same?

If I have many variables I want to initialize with the same value, I use:

a = b = c = ""

Is there a similar shorthand for defining ma开发者_运维知识库ny functions that do the same thing? That is, neither of the following works:

def x() = y() = z():
def x() = def y() = def z():

You can simply assign functions like you would assign variables.

def z():
  whatever

x = y = z

You can't do it in one line if you want to use def, but if you can make it into a lambda you can make a one-liner:

x = y = z = lambda foo: bar()

How about:

def z():
    pass

x = y = z

Uhm... functions are also objects, so you can do this:

def foo():
   pass

bar = foo

As you can see, the syntax is the same.

Why would you WANT to, hell if I know.

you can do soemthing like this:

def X():
    pass

Y = Z = X
