Here's the way you do what you literally asked for:

class MyClass(object):
    def __init__(self, *args):
        # Warning: completely untested
        execfile('')  # may need extra arguments?

but you almost certainly don't want to do that. A better way is by 
importing modules, the same as you would for anything else:

class MyClass(object):
    def __init__(self, *args):
        from AnotherModule import constructor
        constructor(self, *args)

But frankly if you find yourself needing to do this because your file is 
"too big" and is unmanageable, I think you are in desperate need of 
refactoring your code to make if more manageable. Pushing vast amounts of 
random code out into other files just increases the complexity: not only 
do you have vast amounts of code, but you have large numbers of files to 
manage as well.
