Question

我对python很新，并且遇到了许多错误，但我无法修复以下基于客户购买历史类型推荐游戏的代码。

game_name = ["COD1", "COD2", "COD3", "SKYRIM", "H1Z1", "CSGO", "BF1", "BF3", "BF4", "GTAV", "GTAIV", "FIFA17", "NBA2K17", "MADDEN17", "PES2017", "NHL17", "MLB17", "PGA17", "F12017", "NBA2017"]
history = [["COD1", "COD2", "SKYRIM", "H1Z1", "NHL17", "MLB17", "CSGO", "BF1", "BF3", "F12017"], ["FIFA17", "NBA2K17", "MADDEN17", "PES2017", "COD3", "SKYRIM", "MLB17", "PGA17", "NBA2017", "GTAIV"], ["COD2", "COD3", "PES2017", "NHL17", "BF4", "GTAV", "GTAIV", "MLB17", "PGA17", "F12017"]]
forename = ["Joe", "George", "Oliver"]
HistoryGenre=[["Action", "Action", "Action", "Action", "Sport", "Sport", "Action", "Action", "Action", "Sport"], ["Sport", "Sport", "Sport", "Sport", "Action", "Action", "Sport", "Sport", "Sport", "Action"], ["Action", "Action", "Sport", "Sport", "Action", "Action", "Action", "Sport", "Sport", "Sport"]]
rr=1
ActionCounter=0
SportCounter=0
while rr==1:
    rec=input("Who would you like to recommend games for?")
    if rec in forename:
        rr+=1
        r=forename.index(rec)
        ActionCounter = HistoryGenre[r][:10].count("Action")
        SportCounter = HistoryGenre[r][:10].count("Sport")
        if SportCounter==ActionCounter:
            both_list=game_name
            both_remover=0
            for i in both_list:
                if both_list[both_remover] in history[r]:
                    both_list.remove(both_list[both_remover])
                else:
                    both_remover+=1
                    loops=1
            for x in range(1):
                rec1=random.randint(0,len(both_list)-1)
                while loops==1:
                    for x in range(1):
                        rec2=random.randint(0,len(both_list)-1)
                        if rec2!=rec1:
                            loops+=1
                        else:
                            loops=1
                    loops1=1
                    while loops1==1:
                        for x in range(1):
                            rec3=random.randint(0,len(both_list)-1)
                            if rec3!=rec2 and rec3!=rec1:
                                loops1+=1
                            else:
                                loops1=1

                     print("\n")
                     print("{} likes both genres! I recommend {} and {} and {} and {}".format(rec, both_list[rec1], both_list[rec2], both_list[rec3]))

错误消息出现在最后一行代码上，并且读取Tuple index out of range，即使both_list不是tuple？其他人似乎有问题，因为我正在格式化此数组中的索引，但我尝试过的任何东西似乎都没有用，并且出现了相同的错误消息，我不知道究竟是哪个错误源。

看起来format()来电的参数少于你{}的参数。

不明白为什么我的“Tuple索引超出范围”错误
