      Protocols are static duck typing. An object is a valid instance of protocol if it implements all the methods defined in the protocol, even if it doesn't declare it as implementing it. That last bit is important and the most distinguishing factor compared to an ABC.

      From what i understand, Protocol is for custom interfaces that you define (this object must have do_x() method), while ABCs are generic (this object is iterable).
