每次我嘗試編碼時，它都可以工作，但是當我鍵入代碼時'stop'，會出現錯誤：ValueError：以10為底的int（）的無效文字：'stop'def guessingGame(): global randomNum guessTry = 3 while True: guess = input('Guess a Number between 1 - 10, You have 3 Tries, or Enter Stop: ') if int(guess) == randomNum: print('Correct') break if int(guess) < randomNum: print('Too Low') guessTry = guessTry - 1 print('You have, ' + str(guessTry) + ' Guesses Left') if int(guess) > randomNum: print('Too High') guessTry = guessTry - 1 print('You have, ' + str(guessTry) + ' Guesses Left') if guessTry == 0: print('You have no more tries') return if str(guess) == 'stop' or str(guess) == 'Stop': break

這是一個更加Pythonic（Python 3）的版本。
def guessing_game(random_num):
tries = 3
print("Guess a number between 1 - 10, you have 3 tries, or type 'stop' to quit")
while True:
guess = input("Your number: ")
try:
guess = int(guess)
except (TypeError, ValueError):
if guess.lower() == 'stop' :
return
else:
print("Invalid value '%s'" % guess)
continue
if guess == random_num:
print('Correct')
return
elif guess < random_num:
print('Too low')
else:
print('Too high')
tries -= 1
if tries == 0:
print('You have no more tries')
return
print('You have %s guesses left' % tries)

您正在嘗試將字符串“ stop”轉換為整數。該字符串沒有有效的整數表示形式，因此會出現該錯誤。你應該放
if str(guess) == 'stop' or str(guess) == 'Stop':
break
作為第一張支票
另一個建議是在輸入上使用小寫字母，然后檢查小寫字母“ stop”。這樣，您只需要檢查一次，它將捕獲“停止”，“停止”，“斷點”等。
if str(guess).lower() == 'stop':
break
