n object at 0x10e078128>
>>> p = Person(11)
>>> p.dob
11
Although I marked dob as date type, why am I able to assign it an int? So my
question how does type annotation helps, when should we use them and what
advantages it brings?
Thanks,

Here, why super(Role, self).__init__(**kwargs) is used instead of
super().__init__(**kwargs) ? What that Role and self argument is instructing
the super() ?

Ok. My question is that when people add such a class to the module? What

Another question:
My question is that: Can I raise a domain error like

Suppose, if I have the string 'aababbb', I want to get the output as 'aababb'.
I want the output in time complexity O(N) and space complexity O(1). when input
