为什么即使我已经满足了条件，我也会陷入循环？

Question

即使我已经输入了 -100 到 100 之间的分数，我仍然卡住了。为什么会这样？请帮我修一下！players = int(input("Enter number of players: ")) while (players < 2 or players > 10): #Limits number of players to 2-10 only    players = int(input("Error. Players should be 2-10 only. Enter number of players: "))scores = input("Enter scores separated by space: ") data = list(map(int, scores.split())) record = data[slice(players)] for x in record:    while( x < -100 or x > 100):         scores = input("Error. Scores should be -100 to 100 only. Please enter scores again separated by space: ")         data = list(map(int, scores.split()))         record = data[slice(players)] record.sort(reverse= True) values = [] for x in record:    if x not in values:         values.append( x )        if len(values) == 3:             breakprint ("The runner-up score is:",values[1]) 这是发生了什么：Enter number of players: 3Enter scores separated by space: 10000 2 3Error. Scores should be -100 to 100 only. Please enter scores again separated by space: 233 4 5Error. Scores should be -100 to 100 only. Please enter scores again separated by space: 1 2 3Error. Scores should be -100 to 100 only. Please enter scores again separated by space:          可以看到，第三次我已经输入了1 2 3，但是还是报错。请帮助我:(非常感谢您的帮助！

Answer 1

更改此部分：

for x in record:

    while( x < -100 or x > 100): 

        scores = input("Error. Scores should be -100 to 100 only. Please enter scores again separated by space: ") 

        data = list(map(int, scores.split())) 

        record = data[slice(players)] 

到：

while any( x < -100 or x > 100 for x in record):

        scores = input("Error. Scores should be -100 to 100 only. Please enter scores again separated by space: ") 

        data = list(map(int, scores.split())) 

        record = data[slice(players)] 

您的代码不起作用的原因是：

for x in record:

    while( x < -100 or x > 100): 

您正在循环使用那个特定的x. 更新时record，具体x内容将保持不变，因此while循环永远不会中断。

Answer 2

这是根据您的目的编写代码的正确方法：

players = int(input("Enter number of players: ")) 

while (players < 2 or players > 10):

    players = int(input("Error. Players should be 2-10 only. Enter number of players: "))

    continue

现在它会不停地问你，直到玩家人数为 2 - 10。

并更改以下代码：

while any(x < -100 or x > 100 for x in record):

    scores = input("Error. Scores should be -100 to 100 only. Please enter scores again separated by space: ") 

    data = list(map(int, scores.split())) 

    record = data[slice(players)] 

现在应该工作
