Hi,
As I am starting to learn python, I follow dive into python. As I read
object section, I came across something called class attributes and data
attributes. Because of the reason that class attributes look and behave
exactly like static variables in other languages (as I have used in php
for example.) That made me think that, there should be static variables
for functions too (or lets call them function variables?!?). Doing a
little bit research on that, I see that there is no static variable for
functions but we can make things behave like that as introduced here:
http://www.daniweb.com/software-development/python/threads/33025
def egg(static={"count":0}):
static["count"]+=1
return static["count"]
print egg()
print egg()
# >>> 1
# >>> 2
Author of this post says that we can use mutable variables like this as
static function variables. I was wondering what are mutable variables
and what is rationale behind them.
