Question

我的代码存在一些我不知道如何解决的问题。

当我打印出他们选择的游戏和级别的消息时，最后并没有打印出级别（初学者，中级或高级）。它只打印出游戏。我已经将'num'打印出来了，但是我也尝试了'Level'和'number'到位。代码是

打印（“播放”，游戏列表[游戏类型]，“在”，数字）
在询问用户他们想玩什么游戏时，如果他们输入的数字超出0-3或一个字母，则在最后打印消息时，其代码会进一步细分。这只是在询问什么游戏时，而不是在他们想要游戏的级别时。

任何帮助都将不胜感激。

    gamelist = ["Mario Cart","Minecraft","Angry Birds","Grabd Theft Auto"]
    gamecount = 0
    print ("Hello",name,"the four games avaliable are:")
    while gamecount < 4:
        print (gamecount," ",gamelist[gamecount])
        gamecount = gamecount + 1
    gametype = int(input("What number game do you want? (Please choose between 0 and 3) "))

这是输出：
