thanks, very usefull answer.
Immutable types (e.g. strings, numbers, tuples) are generally returned directly from functions, rather than returned as 'output parameters'. The ability to return multiple values easily (via "return a, b, c" & "x, y, z = myfunc()" generally eliminates the need for 'by reference' output parameters as used by C, C++, Java and the like.
P.S. If you *really*, *really*, *really* want to fake output parameters, just wrap them in a list:
return multiple values is ok, I usualy use a function only to return one value, for exemple : value=IsSomething(), returning true, to include that in an if statement : if (isSomething(blabla) ) ... but It's not a problem to change that habit. and as I have read somewhere about python : "Explicit is better than implicit"
Plus, as you get more used to Python you'll also get used to thinking of a tuple as a single composite object.
