`type` is a metaclass that either creates a new class (given 3
arguments: name, bases, and dict) or returns a reference to the class
of an existing object. type(5) is the latter case, and it returns a
reference to the class `int`. What you see printed in the REPL is
repr(int), a string representation of the class object:

     >>> repr(int)
     "<class 'int'>"

Speaking of classes and metaclasses, note that you can't call
int.__repr__(int) to get this representation, because the __repr__
special method of int is meant for instances of int such as int(5).
Instead you have to explicitly use __repr__ from the metaclass, i.e.
`type`:

    >>> type(int)
    <class 'type'>
    >>> type.__repr__(int)
    "<class 'int'>"

But just use built-in repr().
