1. Starmap(func, iterable[, chunksize]) Like map() except that the elements of the iterable are expected to be iterables that are unpacked as arguments. Hence an iterable of [(1,2), (3, 4)] results in [func(1,2), func(3,4)]. 이터레이트 전 함수호출 This method chops(자르다) the iterable into a number of chunks(큰덩어리) which it submits to the process pool as separate tasks. The (approximate) size of these chunks..

더보기 object.__repr__(self) Called by the repr() built-in function and by string conversions (reverse quotes) to compute the “official” string representation of an object. If at all possible, this should look like a valid Python expression that could be used to recreate an object with the same value (given an appropriate environment). If this is not possible, a string of the form should be returne..
