It receives the same arguments as init(), except for the first one that specifies the desired type of the returned instance (MyMetaClass in our case). In our code, we have declared an _init_ method (with one underscore on each side): That is why Python automatically makes classes unhashable if you only implement eq (). The class also has a method get_full_name() method that combines the first name, and last name and returns the full name of the Student. Basic Number Formatting with String#format.
