python 循环中break与continue区别学习

在学习python语言中发现python中跳出循环有两种方法，分别是break和continue，但是两种方法的区别一直不太清楚，也没有找到一个比较明确的说明，经过自己实际编码对比，基本上掌握了用法。首先，写一段python的循环代码，如下：

foods = ["apple", "banan","orange","pear"]for fruit in foods:    if fruit == "banan":        print("No more banna please!")    print("Great, delicious " + fruit)else:    print("I am so glad: No banan!")print("Finally, I finished stuffing myself")

输出结果是：

Great, delicious appleNo more banna please!Great, delicious bananGreat, delicious orangeGreat, delicious pearI am so glad: No banan!Finally, I finished stuffing myself

然后，我们向其中加入break语句，看看结果是什么：

foods = ["apple", "banan","orange","pear"]for fruit in foods:    if fruit == "banan":        print("No more banna please!")        break    print("Great, delicious " + fruit)else:    print("I am so glad: No banan!")print("Finally, I finished stuffing myself")

结果是：

Great, delicious appleNo more banna please!Finally, I finished stuffing myself

在增加break之后，循环跳出了banan之后，直接输出到最后的语句，然后循环结束。那么，continue在循环中有什么作用的，试着用continue替代break，看一下结果是什么：

foods = ["apple", "banan","orange","pear"]for fruit in foods:    if fruit == "banan":        print("No more banna please!")        continue    print("Great, delicious " + fruit)else:    print("I am so glad: No banan!")print("Finally, I finished stuffing myself")

结果是：

Great, delicious appleNo more banna please!Great, delicious orangeGreat, delicious pearI am so glad: No banan!Finally, I finished stuffing myself

可以看出，continue和break是有明显的区别的，只是循环到banan时，跳过，然后继续循环后面的部分，直到代码结束。
