A function which returns several values

When you're not accustomed with Python, it's easy to forget that a function can return just any type of object, including tuples.
This a great to create functions which return several values. This is typically the kind of thing that cannot be done in other languages without some code overhead.
"""
>>> def myfunction(a):
 return (a+1,a*2,a*a)
>>> print myfunction(3)
(4, 6, 9)

"""
You can also use mutiple assignment:
"""
>>> (a,b,c) = myfunction(3)
>>> print b
6
>>> print c
9
"""
And of course your functions can return any combination/composition of objects (strings, integer, lists, tuples, dictionnaries, list of tuples, etc.).
