python显示列表索引必须是整数，而不是元组错误

Question

这是我上一篇文章中另一位用户的代码：

candidates = tempContestants[-2:]
if len(candidates) != 2:
    print("Sorry, not enough players")
    quit()
print("{} and {}, I'm sorry my dears but you are up for elimination".format(
        *candidates))
lipsync()

eliminated = random.choice(candidates)
candidates.remove(eliminated)
safe = candidates[0]
tempContestants.remove(eliminated)

print("""Ladies, I have made my decision.
{}, shantay you stay!
{}, sashay away!""".format(safe, eliminated))

if eliminated == name:
    print("You have been eliminated!")
    quit()

以下是您可能需要了解的一些信息：

tempContestants = contestants

我使用tempCompetities，以便在不影响主要参赛者列表的情况下从列表中删除参赛者并添加新的参赛者。另外，当我想随机挑选一个参赛者时，我不想让程序为两个不同的“类别”挑选同一个参赛者，因此我将他们从列表中删除

它抛出了一个错误，说：

bottom = tempContestants[0,len(tempContestants)-1]
    TypeError: list indices must be integers, not tuple

这意味着什么？如何修复

Answer 1

行bottom = tempContestants[0, len(tempContestants)-1]不正确。 如果要获取最后一个元素，则应改为bottom = tempContestants[-1]。如错误所示，您给出了2个值（一个元组）作为索引，这是不允许的

如果要获得新列表，则必须使用切片，即使用冒号而不是逗号：

tempContestants[:-1]  # get a copy without the last element
tempContestants[:]    # get a complete copy of the list
tempContestants[1:]   # get a copy without the first element

Answer 2

tempContestants[-2:]意味着参加选手的最后两项比赛。如果少于两个，Python将抛出一个超出范围的异常
