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)
但是之后，我想从元组中取出随机字符串，以便可以再次运行随机部分，而不必使用相同的颜色。
您不能更改tuple，只能创建new tuple。如果您使用了list：
AllSands = ["GREEN", "RED", "PINK", "BLACK", "WHITE", "ORANGE", "PURPLE", "BROWN", "GREY"]
found_sand = random.choice(AllSands)
AllSands.remove(found_sand)
当然，更简单的方法是pop根据需要进行改组，从而消除了对以下内容的O(n)搜索和复制工作remove：
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
