[Tutor] <function animals at 0x662f0> what does it mean?

[Mehta, Amar]

the function animals returns a reference to itself.  the reference is
printed in oldMac

oldMac can be changed to remove the print statements

def oldMac():
	animals("cow", "moo")
	animals("pig", "oink")
	animals("horse", "neigh")
	animals("dog", "woof")
	animals("cat", "meow")

you also don't need to return anything from the animals function as it
stands. the function as it stands is merely for side effects (ie
printing various strings).

<function animals at 0x66030> is the location of the code for the
function in the computers RAM.

Hello,
This is my first program calling functions :) It worked nicely except
