python - Updating multiple objects without creating separate variables for them -

in game, "enemies" created objects class level loads.

when screen refreshes, each need update x , y positions. since there multiple enemies, need create long piece of code telling every enemy object update.

for example:

enemy1 = enemy() enemy2 = enemy() enemy3 = enemy() ... enemy1.update() enemy2.update() enemy3.update() ... 

i need way create these objects when needed without needing create variable every single one, , function make objects in enemy class update when screen refreshes.

you can that:

class enemy(object):      def __init__(self):         pass      def update(self):         pass # call function during updates.  enemies = [] iter in range(10):     enemies.append(enemy()) # creating 10 enemies , appending list  enemy in enemies:     enemy.update() #updating every enemy in list 

answer easy. during creating enemy append list. later, if need calculate x/y position iterate on list. remember remove or del enemy list if don't need anymore.
