Is it a bad practice to use "list" as a class-variable?

Question

Example:

class Entity:
list = []
def __init__(self):
Entity.list.append(self)

It shouldn't overwrite anything since the function list belongs to python but not to the class Entity. Is it still a bad practice to do this?

Answer 1

It does overwrite the function, just not on all scopes. The following program throws a TypeError.

class Entity:
list = []
def __init__(self):
Entity.list.append(self)
print(list("Hello world!"))

It may see harmless at first, but for more complex codes it's a really big deal.

Answer 2

Yes
