Changing variables in multiple Python instances

Question

Is there anyway to set the variables of all instances of a class at the same time? I\'ve got a simplified example below:

class Object():
   def __init__(self         


        

Answer 1

"Is there any way to set the variables of all instances of a class at the same time?"

That's a class attribute!

Some examples on how to access a class attribute:

>>> class Object:
...     speed = 5
...     @classmethod
...     def first(cls):
...         return cls.speed
...     def second(self):
...         return self.speed
...
>>> Object.speed
5 
>>> instance = Object()
>>> instance.speed
5
>>> instance.first()
5
>>> instance.second()
5
