For循环内，而循环内要求用户输入条件

Question

我正在编写一个python游戏，它有以下功能可以向用户询问。

1. 最多可以有4名玩家（最少1名玩家，最多4名玩家）
2. 它会问玩家的名字。如果名称已存在，程序将提示“名称已在列表中”，并要求再次输入名称
3. 如果播放器在播放器名称输入中输入空字符串，它将退出。
4. 它会询问玩家想要玩多少n个随机数字（使用randint（开始，停止）。最多只允许3位数字

我知道我必须使用，而循环无限期地询问用户输入，直到满足条件为止。我还必须使用for循环根据第1点的输入向用户询问名称。

以下是我有错误的尝试。因此，在复习时需要你的帮助-

def attempt1():
playerList = []
numPlayers = input("How Many Players? ")
if int(numPlayers) < 5 and int(numPlayers) > 0:
    while True:
        if numPlayers != "":
            for i in range(int(numPlayers)):
                playerName = input("Player name or <Enter> to end ")
                if playerName != "":
                    if playerName not in playerList:
                        playerList.append(playerName)
                    break
                else:
                    print("Player Name Cannot be empty")
                    # numPlayers = input("How Many Players? ")
        else:
            print("There must be at least one player")
            numPlayers = input("How Many Players? ")
else:
    print("Invalid number of players. Please enter 1 - 4")
print(playerList)

def attempt2(numPlayers):
playerList = list()
# numPlayers = 1
i = 0
while i < 4:
    for x in range(0,numPlayers):
        playerName = input("Name ")
        if playerName not in playerList:
            playerList.append(playerName) 
            i += 1
        else:
            print("Name is already in the list")
print(playerList)
return playerList

这解决了我的问题。如果您有更好的解决方案，请提出建议。我肯定我的代码在这里是混乱的，但它目前工作。

def askPlayerName(numPlayers):
playerList = []
x = numPlayers
while True:
    if x > 0:
        for i in range(x):
            print(x)
            playerName = input("Enter name: ")
            if playerName not in playerList:
                x -= 1
                playerList.append(playerName)
                break
            else:
                print("ELSE")
                x = numPlayers - len(playerList)
                print(x)
                print("name aldy in the list")
    else:
        return playerList
return playerList
