python - 如何在我的音乐游戏中解决这个问题？

Question

我目前正在尝试做一个更大规模的项目(就我目前的水平而言)，这是一个音乐游戏。在这段代码中一切正常，但有时，当我尝试“打印 (A)”时(可以在代码的最后一行看到)，它不会显示歌曲的第一个字母，但有时会显示.我不确定这是为什么。
这是代码:

import songsandartists
import random
import sys
import time

Authorised_players = ("jimmy", "tim", "amy", "bob")
Username = input("Please enter your username: ")
if Username.lower() in Authorised_players:
    print("Getting your game ready...")
else:
    print("Sorry you are not an authorised player")
    sys.exit("""
    You are no authorised to play, 
    Try contacting developers to authorise you :)
    EXITING GAME... """)

time.sleep(2)

Random_song = random.choice(songsandartists.Songs)
links = {
    "BOP": "DABABY",
    "NOBODY'S AROUND": "YNW MELLY",
    "LOADING": "CENTRAL CEE",
    "LAUGH NOW, CRY LATER": "DRAKE",
}
Reference = {
    "DABABY": "BOP",
    "YNW MELLY": "NOBODY'S AROUND",
    "CENTRAL CEE": "LOADING",
    "DRAKE": "LAUGH NOW, CRY LATER",
}
if Random_song in links:
    K = links.get(Random_song)
    A = Reference.get(K)[0]
    print(K)
    print(A)

Answer = input("What song do think do you think this artist made that start with the letter above? : ")

points = 0

if Answer.upper() == Random_song in links:
    points += 1
    print("Correct Answer")
    print("You have ", points, " points")
else:
    time.sleep(2)
    K = links.get(Random_song)
    F = Reference.get(K)[0:2]
    print(F)
    sec_attempt = input("You have one more chance, THINK!  : ")
    if sec_attempt.upper() == Random_song in links:
        print("Well done, You got it this time")
        points += 0.5
        print("You have ", points, " points")
    else:
        print("Incorrect, still wrong")

几分钟之内，我意识到了我愚蠢的错误。在我导入的“歌曲和艺术家”文件中，所有歌曲和艺术家的名字都是小写的，我在我的音乐游戏的字典中将它们写成大写，导致它们无法工作，因为在字典中找不到它们。所以基本上，当我试图从字典中搜索并获取“东西”时，它无法因此禁止我从字典中打印任何内容。
多么愚蠢的错误...... smh。
