i've been having use c# lately, don't have experience in. conundrum keep finding myself in is, when building class, having state dependent on state initialized before it class foo{ public bar_ {get;} public dum_ {get;} public foo (){ bar_ = buildbar(); dum_ = builddum(bar_); } } its bit redundant builddum carry parameter if it's going use accessable member. on other hand explicitly pointing out dependencies function relies on i guess asking: best way handle situation? both ways fine. current version of builddum made static , in case it's fine method not access member variables, because cannot anyway: private static dum builddum(bar b) { ... } if make builddum accesses bar_ directly, should make access _dum , i.e. should non-static void : private void builddum() { ... _dum = ... }

i want know how python programmers write following snippet: for in range(10): indexvector[i] = empavg[i] + upperbound(t, pullcount[i]) here t constant. can see, used c/c++ style code want use python right way. if want use list comprehension create indexvector (assuming not have other value outside 10 indexes entered in snippet) , can use - indexvector = [empavg[i] + upperbound(t, pullcount[i]) in range(10)]
