Question

我正在为称为编程入门的课程做一些功课。我正在制作一个带有字典列表的小型查找应用程序。我只是想知道我能做些什么，以便用户可以输入“ pubg”而不是“ PUBG”？我在所有地方都尝试过.lower（），但是因为我不太了解它的工作原理，所以我不知道需要更改什么。

import sys
while True:
    print("-" * 45)
    print("\n" "Welcome to game creator lookup!")





    game_list = {
            "Battlefield" : "EA DICE",
            "Fortnite" : "Epic Games",
            "Counter strike" : "Valve",
            "PUBG" : "PUBG Corporation",
            "Overwatch" : "Blizzard",
            "Dota" : "Valve",
            "Call of duty" : "Infinity Ward",
            "The sims" : "EA, Maxis, Firemoney studios"}



    choice = (input("What game would you like to look up? (Type 'q' to quit) " "\n"))
    if choice in game_list:
        print (choice, "was created by", game_list[choice])

    if choice == ("q"):
        print("goodbye")
        sys.exit()

    elif choice not in game_list:
        print("Invalid choice, try again")

Answer 1

以这种方式重写游戏列表：

game_list = {
        "battlefield" : ("Battlefield", "EA DICE"),
        "fortnite" : ("Fortnite", "Epic Games"),
        "counter strike" : ("Counter strike", "Valve"),
        "pubg" : ("PUBG", "PUBG Corporation"),
...

（实际上，此重写可以使用适当的功能自动完成）

然后您就可以使用

choice = choice.lower()

if choice in game_list:
    print (game_list[choice][0], "was created by", game_list[choice][1])

“ pubg”而不是“ PUBG”-区分大小写的输入问题
