return multiple values from fuction

[Lupe]

hi, if someone can help me I would be grateful

when I do

def function
kjklj
llklç

return variableA, variableB

how can I assign the two return values to two distinct variables, as for ex.

varC = variableA
varD = variableB

??

def test ():

return variableA, variableN


varC, vardD = test()

varC will contain variableA
varD ill contain variableB

By using tuple unpacking:

(varC, varD) = function()

this needs of course to be

def function():
[color=blue]

"just do it":

varC, varD = function()

I like that comment... "just do it"...
I find this is also true for most other things
that you want to do in Python.

"How do I create a mapping between a person's last
name and the list of telephone numbers he/she can be
reached at?" -- "umm.. just do it?"

{ "de Jong": ['234234', '34562363'] }

or whatever ;-)

I'm starting with Python and I find it really great!

It's... natural!
