This lecture is talking about the Class detail and application.
If you use a function, you can add different argument.
keyword Arguments and Positional Arguments.
I think that is different writing style.
pass(you can choose return or pass)
#arg = Positional Arguments
#kwarg = Keyword Argumentabc = “new string”
def some_func(arg_1, arg_2, kwarg_1=None, kwarg_2=None):
print(arg_1, arg_2) if kwarg_1 != None: print(kwarg_1)
If you maintain the code, you can easily refer the location which the argument should change and operate.
I can use the property to call the function without ().
