Python Instantiate Class Within Class Definition

Question

I am attempting to add a variable to a class that holds instances to the class. The following is a shortened version of my code.

class Classy :
    def __in         


        

Answer 1

The simplest way to do this is do it after the class is created, when the class has been defined, and therefore can be used:

class Classy :
    CLASSIES = []

    def __init__(self) :
        self.hi = "HI!"

Classy.CLASSIES = [Classy() for _ in xrange(0,4)]

(Here using a list comprehension for convinience, as it's the most readable and efficent way to build a list).

Also note that if this intended to be a constant, you should probably make it a tuple rather than a list, and if it isn't intended to be, you should probably not use an ALL_CAPS name which, by convention, implies a constant.
