Python 在3个字符串列表中生成所有可能的元素组合？

我需要生成每个字符串列表中每个元素的所有可能组合

list1 = ['The girl', 'The boy']
list2 = ['wears', 'touches', 'tries']
list3 = ['a red sweater', 'a blue sweater', 'a yellow sweater', 'a white sweater']

因此，结果是一个字符串列表，该字符串组合了每个元素和其他元素：

The girl wears a red sweater
The boy wears a red sweater
The girl touches a red sweater
The boy touches a red sweater
The girl wears a blue sweater
The boy wears a yellow sweater
(ETC...)

我并不特别关心输出的顺序，只要获得了所有的组合

根据我的研究，我猜“排列”是一个解决方案，但我只找到了几个关于数字列表排列或字符串中每个字母组合的答案。这些东西都不是我需要的。我需要组合在列表中排列的文本块

如何创建一长串句子，其中包含每个字符串列表中不同元素的所有组合

谢谢你

只要一堆简单的for循环就行了。诀窍是打印顺序

z，y，x

list1 = ['The girl', 'The boy']
list2 = ['wears', 'touches', 'tries']
list3 = ['a red sweater', 'a blue sweater', 'a yellow sweater', 'a white sweater']

for x in list3:
    for y in list2:
        for z in list1:
            print (z,y,x)

使用itertools的产品，其操作非常简单：

import itertools
["{x} {y} {z}".format(x=x,y=y,z=z) for x,y,z in itertools.product(list1, list2, list3)]

在Python3.6中，您可以放弃

format

调用

[f"{x} {y} {z}" for x,y,z in itertools.product(list1, list2, list3)]

我试过了，但在路上弄糊涂了。非常感谢。我试过了，但在路上弄糊涂了。非常感谢。
