Python 简单的验证会导致无限的While循环

我目前正在为一个事件制作一个记分系统，但在使用while循环验证用户输入时遇到了问题。例如，我想强制用户输入他们的姓名，以便将其添加到我使用字典搜索的网球等运动的位置。每次我要求他们输入他们的用户输入时，while循环就一直在进行，导致了一个永无止境的while循环。这就是我所做的

  ```solo_player = {
"Contestant 1":{"Player 1":[],"Score":[],"Event":[]},
"Contestant 2":{"Player 2 ":[],"Score":[],"Event":[]},
"Contestant 3":{"Player 3":[],"Score":[],"Event":[]},
"Contestant 4":{"Player 4":[],"Score":[],"Event":[]}}

 def individual():
  solo_name = False
  while not solo_name:
 solo_name = input("What is your name:")
 print(""" \nIndividual Menu and Available Spots\n
  1) Player 1
  2) Player 2
  3) Player 3
 \n4) Go back to Main Menu\n""")

 solo_menu = ["1","2","3","4"] #valid choices for this menu
 solo_menu = False
 while not solo_menu:
   solo_menu = input("Please enter your choice here:")

   if solo_menu == "1":
    solo_player["Contestant 1"]["Player 1"].append(solo_name)
    print(solo_player["Contestant 1"])
    print("Thank you for taking the spot of Player 1")
    solo_menu = True

   elif solo_menu == "2":
    solo_player["Contestant 2"]["Player 2"].append(solo_name)
    print(solo_player["Contestant 2"])
    print("Thank you for taking the spot of Player 2")
    solo_menu = True

    else: 
     print("Enter a value between 1-4)
     solo_menu = False```

我的理想输出是，当我从可用点中选择一个点后，while循环将停止。很抱歉，if/else语句太长了，我对它很陌生，所以我不知道如何缩短它

编辑：我解决了这个问题。这是由于在我的菜单def之外调用单个func造成的。

以下是我相信您想要的

有几个变化：

while循环可以包含要作为其条件执行的验证。如果您的验证变得更加复杂，那么您可以考虑返回到布尔来打破while循环，但是对于您的要求来说，它过于复杂。

删除if语句。字典的整体思想是，您可以指定一个键并获取一个值，因此为每个潜在键设置

elif

过于繁琐。只需连接已验证的用户输入即可派生密钥

在您发布的代码中，缩进是完全错误的，因此我们无法真正说出循环和函数的确切含义。您能否尝试将代码包装在代码块中，通过三个勾号“I ll try and fixed”来修复它？请提供预期的（MRE）。我们应该能够复制和粘贴一个连续的代码块，执行该文件，并再现您的问题以及跟踪问题点的输出。这让我们可以根据您的测试数据和期望的输出来测试我们的建议。您发布的代码无法运行。它挂起等待输入——不要期望我们输入测试数据。相反，只需硬编码一个导致问题的测试用例；删除额外的案例，即初始化开销。您还必须测试程序的较小部分，以便我们集中精力解决一个问题。扫描您的代码至少会显示三个。很抱歉复制了整个代码，我会尽量缩短它。感谢这位男士solo_player=“”到底应该做什么？我对编程很陌生，所以IdkI在代码中看不到

solo\u player=”“

。我的坏意思是你给我的答案上的

solo\u menu=“”

，我在尝试使用代码时似乎遇到了与以前相同的问题

solo_player = {
"Contestant 1":{"Player 1":[],"Score":[],"Event":[]},
"Contestant 2":{"Player 2":[],"Score":[],"Event":[]},
"Contestant 3":{"Player 3":[],"Score":[],"Event":[]},
"Contestant 4":{"Player 4":[],"Score":[],"Event":[]},
"Contestant 5":{"Player 5":[],"Score":[],"Event":[]},
"Contestant 6":{"Player 6":[],"Score":[],"Event":[]},
"Contestant 7":{"Player 7":[],"Score":[],"Event":[]}}


solo_name=""    
while solo_name == "":
    solo_name = input("What is your name:")
    print(""" \nIndividual Menu and Available Spots\n
        1) Player 1
        2) Player 2
        3) Player 3
        4) Player 4
        5) Player 5
        6) Player 6
        7) Player 7
        \8) Go back to Main Menu\n""")

#prompt for player slot
solo_menu_options = ["1","2","3","4","5","6","7","8"] #valid choices for this menu
solo_menu=""
while solo_menu not in solo_menu_options:
    solo_menu = input("Please enter your choice here:")    

solo_player["Contestant "+solo_menu]["Player "+solo_menu].append(solo_name)
print(solo_player["Contestant "+solo_menu])
print("Thank you for taking the spot of Player "+solo_menu)
