在Python中使用多个列表进行循环 [英] For loop using more than one list in Python

问题描述

我正在寻找解决问题的方法.目前，我有两个元素列表:

I'm looking for solution to my problem. At the moment I have two list of elements:

column_width = ["3", "3", "6", "8", "4", "4", "4", "4"]
fade = ["100", "200", "300"]

我要实现的是创建for循环，该循环将为我提供以下输出:

What I want to achieve is to create for loop which wil give me following output:

column-3-fade-100
column-3-fade-200
column-6-fade-300
column-8-fade-100
column-4-fade-200
...

嵌套循环对我不起作用

for i in fade:
    for c in column_width_a:
        print("column-{0}-fade-{1}".format(c, i))

还有其他方法可以生成此输出吗?

Is there any other way to generate this output?

推荐答案

这是使用 itertools.cycle .

例如:

from itertools import cycle

column_width = ["3", "3", "6", "8", "4", "4", "4", "4"]
fade = cycle(["100", "200", "300"])

for i in column_width:
    print("column-{}-fade-{}".format(i, next(fade)))

输出:

column-3-fade-100
column-3-fade-200
column-6-fade-300
column-8-fade-100
column-4-fade-200
column-4-fade-300
column-4-fade-100
column-4-fade-200
