python - 从元组中取出一个字符串 - python

Question

我有一个元组和一个随机字符串:

AllSands = "GREEN", "RED", "PINK", "BLACK", "WHITE", "ORANGE", "PURPLE", "BROWN", "GREY"
found_sand = random.choice(AllSands)

但之后，我想从元组中取出随机字符串，这样随机部分可以再次运行，而不是相同的颜色。

你不能改变 tuple , 只创建新的 tuple秒。如果您使用 list 会更容易做到:

AllSands = ["GREEN", "RED", "PINK", "BLACK", "WHITE", "ORANGE", "PURPLE", "BROWN", "GREY"]
found_sand = random.choice(AllSands)
AllSands.remove(found_sand)

当然，更简单的是洗牌和pop根据需要，删除 O(n)搜索并复制 remove 的作品:

AllSands = ["GREEN", "RED", "PINK", "BLACK", "WHITE", "ORANGE", "PURPLE", "BROWN", "GREY"]
random.shuffle(AllSands)
found_sand = AllSands.pop()  # Each time you call pop, you "find" a new value
