其他语言中，比如C＃，我们通常遍历数组是的方法是：

for (int i = 0; i list.Length; i++)
{
    //todo with list[i]
}

在Python中，我们习惯这样遍历：
for item in sequence:
    process(item)

这样遍历取不到item的序号i，所有就有了下面的遍历方法：
for index in range(len(sequence)):
    process(sequence[index])

其实，如果你了解内置的enumerate函数，还可以这样写：
for index, item in enumerate(sequence):
    process(index, item)
