...多个一维向量进行交叉的迭代操作，建立一个迭代器数组its和一个计位器index。初始化：将迭代器数组初始化为ArrayList()，再将向量数组vecs循环使用迭代器并加入迭代器数组，然后将计位器初值设为0。hasNext()方法：只要迭代器数...

...我们就来验证一下列表为什么支持迭代： >>> x = [1,2,3] >>> its = x.__iter__() # x有此方法，说明列表是可迭代对象 >>> its >>> its.__next__() # its有此方法，说明its是迭代器 1 >>> its.__next__() 2 >>> its.__next__() 3 >>> its.__next__() Traceba...
