good morning/afternoon i want create object whitch simulate array, new browsers no pb change proto of array mine oldest version of ie need know length of false array finding last index. have found way ie: var getlastpos = function(){ for( var in falsearray){ //do nothing } return } but if faster way exists, rather like. try pass regex lastindexof seems don't work thanks. when want find last index array, use <array>.length so not need loop, , function, use falsearray.length if need value last position use this: falsearray[falsearray.length-1] //decrement one, because index array starts 0 i hope helpful.

it possible store condition in variable, rather immediate return it, when declare it? example: a = 3 b = 5 x = (a == b) print(x) = 5 print(x) the return is false false however, expected get false true i'm having fun magic of python. know possible using function, wonder if possible using variable. the condition evaluated immediately. if want evaluate on demand, make function or lambda expression: x = lambda: == b print(x()) also, black magic , make class evaluates condition when it's printed: class condition: def __init__ (self, cond): self.cond = cond def __str__ (self): return str(self.cond()) x = condition(lambda: == b) print(x) this educational purposes though, don't use in production. note onl works in print statements - make work in if statements etc have override __bool__ (python 3) or __nonzero__ (python 2).
