[triangle-zpug] static list in python

[Josh Johnson]

I recall two meanings for static in programming. Static can mean a 
persistent value, like an internal counter in a list (I think that's 
what you want), but I've also heard the term mean "a class method that 
is accessed like a library instead of an instance method".

The latter is easy, you just put a function in a python script:

e.g. in mymodule.py:

def myfunction():
    pass

you can access it by:

 >>> import mymodule
 >>> mymodule.myfunction()

I'm not sure if python supports the sort of persistent variable I think 
you want (anybody else know?). If not, you may have to start with a list 
and have that list be returned by your function and then subsequently 
passed to it again:

 >>> def myfunc(l):
...    l.append('1')
...    return l
 >>> myl = []
 >>> myl = myfunc(myl)
 >>> myl = myfunc(myl)
 >>> myl
['1', '1']
