python call function on whole class

Question

I'm playing around for the first time with pygame, I'd like to know if there is a way I can call a function on a whole class like so:

class Char():
def __init__(self,typ,sid):
    self.type=typ
    self.x=0
    self.y=0
    self.vx=0
    self.vy=0
    self.frame=0
    self.sid=sid
    self.bord = sheets[sid].get_rect()
    self.rct = pygame.Rect((0,0),(self.bord.bottom,self.bord.bottom))

player = Char("player",0)
test = Char("test",1)

myfunct(#All Chars())

This is how I plan on implementing a few simple physics that I'd like to all apply to each Char(), full code here .

You could add them all to a list which is a class variable, like so:

class Char():
    all = []
    def __init__(self,typ,sid):
        self.type=typ
        self.x=0
        self.y=0
        self.vx=0
        self.vy=0
        self.frame=0
        self.sid=sid
        self.bord = sheets[sid].get_rect()
        self.rct = pygame.Rect((0,0),(self.bord.bottom,self.bord.bottom))

        self.all.append(self)

player = Char("player",0)
test = Char("test",1)

myfunct(Char.all)

And if you want to apply your function to each object individually, you can just use a map(myfunct, Char.all) , but you probably knew that.
