If the passed iterators have different lengths, the iterator with the least items decides the length of the new iterator. zip 方法在 Python 2 和 Python 3 中的不同:在 Python 3.x 中为了减少内存,zip() 返回的是一个对象。如需展示列表,需手动 list() 转换。 Syntax zip(iterator1, iterator2, ...

def zip(*iterables): sentinel = object() iterators = [iter(it) for it in iterables] while iterators: result = [] for it in iterators: elem = next(it, sentinel) if elem is sentinel: return result.append(elem) yield tuple(result) So the function takes in arbitrary number of iterable...
In this step-by-step tutorial, you'll learn how to use the Python zip() function to solve common programming problems. You'll learn how to traverse multiple iterables in parallel and create dictionaries with just a few lines of code.
