You could equally write ``for i in generate_ints(5)``, or ``a,b,c =

generate_ints(3)``.
|

|

Inside a generator function, the ``return`` statement can only be used without a
|
||||
value, and signals the end of the procession of values; after executing a
|
||||
``return`` the generator cannot return any further values. ``return`` with a
|
||||
value, such as ``return 5``, is a syntax error inside a generator function. The
|

end of the generator's results can also be indicated by raising
|

:exc:`StopIteration` manually, or by just letting the flow of execution fall off
|

the bottom of the function.
|
||||
Inside a generator function, ``return value`` is semantically equivalent to
|
||||
``raise StopIteration(value)``. If no value is returned or the bottom of the
|
||||
function is reached, the procession of values ends and the generator cannot
|

return any further values.

You could achieve the effect of generators manually by writing your own class

and storing all the local variables of the generator as instance variables. For
