Thanks Chris!
At least my code isn't (quite!) as bad as the xkcd example :)
Guess my "concern" is using the initialized array in the function:
def myfunct(a, b, c=array[0,1,2,3] )
always feels like an abuse.
Has anyone seriously considered implementing a true static variable in a
function? Is there a PEP?
You can emulate a static variable is with a closure.
def make_parseStack():
depth = 0
def parseStack(inc):
nonlocal depth
if depth > 50:
... report error and die nicely
depth += inc
return parseStack
parseStack = make_parseStack()
funny !
So we found 4 different ways to handle a memory in a function
1- Use a function parameter with a mutable default value
2- Use a function attribute
3- Use a callable object, and store your stuff inside an object attr
4- Use a closure to emulate a static function variable
Any more ?
