...多個一維向量進行交叉的迭代操作，建立一個迭代器數組its和一個計位器index。初始化：將迭代器數組初始化為ArrayList()，再將向量數組vecs循環使用迭代器并加入迭代器數組，然后將計位器初值設為0。hasNext()方法：只要迭代器數...

...我們就來驗證一下列表為什么支持迭代： >>> x = [1,2,3] >>> its = x.__iter__() # x有此方法，說明列表是可迭代對象 >>> its >>> its.__next__() # its有此方法，說明its是迭代器 1 >>> its.__next__() 2 >>> its.__next__() 3 >>> its.__next__() Traceba...
