[Python] Accessing parent class attribute from sub-class body

I have a class Klass with a class attribute my_list. I have a subclass of it SubKlass, in which I want to have a class attribute my_list which is a modified version of the same attribute from parent class:

class Klass():
my_list = [1, 2, 3]


class SubKlass(Klass):
# this works, but I must specify parent class explicitly
my_list = Klass.my_list + [4, 5]

# SystemError: super(): __class__ cell not found
#my_list = super().my_list + [4, 5]

# NameError: name 'my_list' is not defined
#my_list = my_list + [4, 5]


print(Klass.my_list)
print(SubKlass.my_list)


So, is there a way to access parent class attribute without specifying its name?
