Question

我目前正在做一个与音乐播放列表有关的项目，我需要能够打印特定歌手和歌曲的首字母，以便用户猜测歌手和歌曲必须是随机强>。我为每个艺术家和歌曲制作了一个单独的阵列，但是我不知道如何随机选择这些阵列之一供我使用。

这是我的数组代码：

BTS = ["Idol", "BTS"]
SWIFTY = ["Love Story", "Taylor Swift"]
RUTH = ["Lost Boy", "RuthB"]
ED = ["Perfect", "Ed Sheeran"]
ARIANA = ["No Tears Left To Cry", "Ariana Grande"]
DRAKE = ["In My Feeling", "Drake"]
RICKY = ["La Vida Loca", "Ricky Martin"]
IU = ["BBIBBI", "IU"]
BTS2 = ["Magic Shop", "BTS"]
PSY = ["Gangnam Style", "PSY"]

如何随机选择这些阵列之一？

Answer 1

random.choice()可以解决问题。

import random
random.choice((BTS,SWIFTY,RUTH,ED,ARIANA,DRAKE,RICKY,IU,BTS2,PSY))

您应该使用字典，如果轨道数量增加，它将使您的代码更易于维护：

musics = {
'BTS' : ["Idol", "BTS"],
'SWIFTY' : ["Love Story", "Taylor Swift"],
'RUTH' : ["Lost Boy", "RuthB"],
'ED' : ["Perfect", "Ed Sheeran"],
'ARIANA' : ["No Tears Left To Cry", "Ariana Grande"],
'DRAKE' : ["In My Feeling", "Drake"],
'RICKY' : ["La Vida Loca", "Ricky Martin"],
'IU' : ["BBIBBI", "IU"],
'BTS2' : ["Magic Shop", "BTS"],
'PSY' : ["Gangnam Style", "PSY"]}

import random
random.choice(list(musics.values()))

如果您有多个阵列，如何随机选择多个阵列之一？
