python. numbers = [1, -2, 3, -4, 5] for num in numbers: if num < 0: continue #跳到下一次迭代。 print(num)。 在这个例子中,loop next指令(continue)用于跳过负数(-2和-4),只打印正数(1、3和5)。如果没有loop next指令,所有的数字都会被打印出来。 Loop next也可以在其他编程语言中使用,...
Python's next function is designed to be used with iterators.You can think of an iterator in two ways:Iterators are iterables that perform work as you loop over them (they're lazy) and are consumed as you loop over them Iterators are the objects that power all iterables in Python...
大家好,前面已经介绍过循环结构的for..next和do...loop系列语句。还有一种用于处理对象集合的循环语句,即for each...next语句,在本节介绍。(下面程序控制结构图帮助回顾) For each...next语句是在集合的对象中循环,对集合中满足某种条件的对象或所有对象执行操作。
在Python for循环中,当你输入如下: for item in iterable: do_stuff(item) 你有效地得到了这个: iterator = iter(iterable) try: whileTrue: item = next(iterator) do_stuff(item) except StopIteration: pass 调用“iter”函数来创建迭代器,然后在循环中多次调用该函数的“next”来获取下一个条目。直到我们...

Private Sub forloop2() Dim x, i As Integer x = 5 For i = 0 To x Step 2 Debug.print "The value of i is : " & i Next End Sub In the above example we have mentioned the step counter as 2, so every time the loop is incremented by 2. Hence the value of I is 0,2,4 as...
