Ok, thx
But can I somehow determing how many outputs does caller func require?
for example:
MATLAB:
function [objFunVal firstDerive secondDerive] = simpleObjFun(x)
objFunVal = x^3;
if nargout>1
firstDerive = 3*x^2;
end
if nargout>2
secondDerive = 6*x;
end

So if caller wants only
[objFunVal firstDerive] = simpleObjFun(15)
than 2nd derivatives don't must to be calculated with wasting cputime.
Is something like that in Python?
