python - How can I call the metaclass's __call__? - given next illustration on instance of x class: class x(): def __call__(self, incoming_list): print incoming_list x()([x x in range(10)]) how can obtain same output using __call__ magic method class instead of instance? example: x([x x in range(10)]) calling directly, if passing __init__ . but, before calls __call__ calls __new__ passes arguments __init__ . how can access "metaclass __call__ " ? possible? just create easier understand, gives me same output there: class x: def __call__(self, incoming_list): print incoming_list x().__call__([x x in range(10)]) i want this: class x: def x.__call__(incoming_list): # syntax error print incoming_list x.__call__([x x in range(10)]) i think think complicated. probably want like class x: def __init__(self, incoming_list): self.data = incoming_list # maintain them later, if need...

c# - Insert values for all 2nd columns of a 1st column of a 2D array - i'm trying question says. (it might confusing) here code should create understand i'm trying do. classes = new string[14, 5]; classes[0] = {"value1 [0, 0]", "value2 [0, 1]", "value3 [0, 2]", "value4 [0, 3]", "value5 [0, 4]"}; some languages or environments(like matlab) allow such things work, c# doesn't provide such access rectangular arrays string[x, y]. with such arrays should alter each element individually: string[,] classes = new string[14, 5];classes = new string[14, 5]; int32 rowtochange = 0; for(int32 col = 0; col < classes.getlength(1); col++) { classes[rowtochange, col] = string.format("value{0} [{1}. {0}]", rowtochange , col ); } but utilize jagged arrays : string[][] string[][] classes = new string[14][]; int32 rowtochange = 0; classes[rowtochange] = new string[]{"value1 [0, 0]", ...
