Python enumerate遍历数组示例应用
(编辑:jimmy 日期: 2025/2/27 浏览:3 次 )
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)
