如何在 Python 上打印几个 arrays 字符串的每个可能排列？

Question

假设我有以下 arrays 字符串：

Background = {"Ocean"}
Body = {"Normal"}
Eyes = {"Big", "Small", "Monolid"}
Color = {"Yellow", "White", "Red Rose", "Turquoise", "Dark green", "Orange"}
Hands = {"None", "Robot", "Spider", "Bear"}
Extra = {"Empty", "Sand", "Dust", "Graffiti", "Aloe"}

我想打印一个列表，其中包含上面 arrays 中提到的每个元素的所有可能排列，按照设置这些 arrays 的顺序（即它开始检查Background ，然后检查Body ，然后是Eyes ，然后是Color ，然后Hands ，并在Extra上完成）。

第一个排列应该是：

1. Ocean, Normal, Big, Yellow, None, Empty

第二个排列应该是：

2. Ocean, Normal, Big, Yellow, None, Sand

等等...

可以假设项目None与Empty相同。

我怎么能那样做？

Answer 1

以下解决方案应该有效假设 arrays 如下

Backgrounds = ["Ocean"]
Bodys = ["Normal"]
Eyes = ["Big", "Small", "Monolid"]
Colors = ["Yellow", "White", "Red Rose", "Turquoise", "Dark green", "Orange"]
Hands = ["None", "Robot", "Spider", "Bear"]
Extra = ["Empty", "Sand", "Dust", "Graffiti", "Aloe"]
for background in Backgrounds:
    for body in Bodys:
       for eye in Eyes:
           for colour in colours:
                 for hand in Hands:
                      for extra in extras:
                             print(background,body,eye,colour,hand,extra)

如果您的列表非常大，请不要使用上述解决方案，因为它的时间复杂度是 o(n^6)。
