即使我已經輸入了 -100 到 100 之間的分數，我仍然卡住了。為什么會這樣？請幫我修一下！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]) 這是發生了什么：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，第三次我已經輸入了1 2 3，但是還是報錯。請幫助我:(非常感謝您的幫助！

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)]
您的代碼不起作用的原因是：
for x in record:
while( x < -100 or x > 100):
您正在循環使用那個特定的x. 更新時record，具體x內容將保持不變，因此while循環永遠不會中斷。

這是根據您的目的編寫代碼的正確方法：
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
現在它會不停地問你，直到玩家人數為 2 - 10。
并更改以下代碼：
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)]
現在應該工作
