python - python显示列表索引必须是整数，而不是元组错误

问题描述

这是我上一篇文章中另一个用户的代码： 

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：

print('''Which group of queens do you want to compete against?
1. Winners
2. Runner-ups

7. One of the seasons''')

choice = int(input())
while choice > 7 or choice < 1:
    print("Please choose one of the 7 groups")
    choice = int(input())

if choice == 7:
    print('''

    choice = int(input())
    while choice > 16 or choice < 1:
        print("Please choose one of the 16 seasons")
        choice = int(input())
    contestants = season_options[choice]
else:
    contestants = group_options[choice]

tempContestants = contestants

我使用 tempContestants 以便我可以从列表中删除参赛者并添加新的参赛者，而不会影响主要参赛者列表。另外，当我想随机选择一个参赛者时，我不希望程序为两个不同的“类别”选择同一个参赛者，因此我将它们从列表中删除。

它抛出一个错误说：

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

这是什么意思，我该如何解决？

标签： python

解决方案

线路bottom = tempContestants[0, len(tempContestants)-1]不正确。如果你想得到最后一个元素，它应该是bottom = tempContestants[-1]。如错误所示，您将 2 个值（一个元组）作为索引，这是不允许的。

如果您想获得一个新列表，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
