I'm watching a Python course and was presented a topic regarding classes. One of the examples were:
box.py class Box: serial = 100 def __init__(self, from_addr, to_addr): self.from_addr = from_addr self.to_addr = to_addr self.serial = Box.serial Box.serial += 1 from box import * a = Box('19 Beech Ave. Seattle, WA 98144', '49 Carpenter Street North Brunswick, NJ 08902') b = Box('68 N. Church Dr. Vicksburg, MS 39180', '8 Lake Forest Road Princeton, NJ 08540') print(a.serial) # print: 100 print(b.serial) # print: 101 print(Box.serial) # print: 102 The instructor said that the right way to call a class attribute is to use 'Class.class_attr' notation, but on the web I found examples where people used 'self.class_attr' to call class attributes. I believe that using the first notation is better ('Class.class_attr'), this way the code is more explicit, but is there any rules regarding it? -- https://mail.python.org/mailman/listinfo/python-list
