即使从列表框中删除，列表框中的字符仍会被记录

Question

所以我的小游戏被编程为让两个角色互相争斗。一个在左侧，一个在右侧。在他们战斗之后，无论谁赢谁输，都应该删除他们。事实上，它们是从列表框中删除的，但当你从每一方都有两个以上的角色时，前面的角色有时会出现。如果你从Zys和Rash fighting开始，那么除了他们的名字外，赢与输部分没有其他名字。只有当你从但丁和伊洛拉那里后退时，它才会以应有的方式工作，每个角色只在一次胜负中占有一席之地。如果你从其他角色开始，他们可能会被放在赢和输的部分不止一次。一个角色即使没有被选中参战，也有可能被视为赢或输。底线是每个角色与对方的角色战斗一次，然后放置并删除它，在程序的后面部分没有任何用处。出于某种明显的原因，它没有做到这一点

这只是代码中与问题相关的部分，而不是整个代码

这不是昨天的问题，只是相同的代码。我认为将bug作为不同的问题一次处理一个更合适，这样它们就可以更有组织性

问题是因为您总是使用if left == 0: namel = "Rash" even if“Rash”was deleted from listbox and nowleft==0means“Untss”

您必须获取选定的名称而不是索引

    namel = lbox.get(lbox.curselection()[0])
    namer = rbox.get(rbox.curselection()[0])

并使用它

    if namel == "Rush":
       totalleft = Rash.total

但你们可以使用字典来获取数据

left_characters = {        
    "Rash": Character("Rash", 42, 50, 80),
    "Untss": Character("Untss", 15, 54, 100),
    "Ilora": Character("Ilora", 60, 35, 80),
}

right_characters = {
    "Zys": Character("Zys", 12, 97, 83),
    "Eentha": Character("Eentha", 55, 17, 90),
    "Dant": Character("Dant", 73, 28, 88),
}

leftnames = list(left_characters.keys())
rightnames = list(right_characters.keys())

然后

def fight():

    try:
        namel = lbox.get(lbox.curselection()[0])
        namer = rbox.get(rbox.curselection()[0])

        print(namel)
        print(namer)

        totalleft = left_characters[namel].total
        totalright = right_characters[namer].total

        lbox.delete(lbox.curselection()[0])
        rbox.delete(rbox.curselection()[0])

        if totalleft > totalright : #Checks if won or lost
            wins.set(wins.get()+"\n"+namel)
            loss.set(loss.get()+"\n"+namer)
        else:
            wins.set(wins.get()+"\n"+namer)
            loss.set(loss.get()+"\n"+namel)
    except IndexError as e:
        print("ERROR:", e)

若你们在字典中添加了新字符，那个么你们就不需要修改代码了

顺便说一句：不要在except中使用pass，因为如果代码有问题，您不会看到错误
