在Python中執行while循環時不返回任何值

Question

獲得最高分數而不獲得相同數字的遊戲。這是在課堂上作爲一項任務，並通過while循環運行時獲得打印位，然後在下一行None。請，因爲沒有人在我們的A級賽事，也沒有老師會在哪裏工作就已經錯了幫助..

from random import randint 
game = True 
score = 0 

die1 = randint(1,6) 
die2 = randint(1,6) 

while game == True: 
    if die1 == die2: 
     score = 0 
     game = False 
    else: 
     score = score + die1 + die2 
     goagain = input(print("do you want another go? Y or N")) 
     if goagain == "N" or goagain == "n": 
      game = False 
     else: 
      print("your current score is:" , score) 

print("game over!! \nYour score is:" , score)

就從輸入中刪除「打印」擺脫無的：

from random import randint 
game = True 
score = 0 

die1 = randint(1,6) 
die2 = randint(1,6) 

while game == True: 
    if die1 == die2: 
     score = 0 
     game = False 
    else: 
     score = score + die1 + die2 
     goagain = input("do you want another go? Y or N") 
     if goagain == "N" or goagain == "n": 
      game = False 
     else: 
      print("your current score is:" , score) 

print("game over!! \nYour score is:" , score) 

但我不認爲這是你想要的 - 你不重複死亡，所以你只是不斷增加相同的數字，直到用戶停止。我想你想放模輥環的內側，這樣的：

from random import randint 
game = True 
score = 0 

while game == True: 
    die1 = randint(1,6) 
    die2 = randint(1,6) 
    if die1 == die2: 
     score = 0 
     game = False 
    else: 
     score = score + die1 + die2 
     goagain = input("do you want another go? Y or N") 
     if goagain == "N" or goagain == "n": 
      game = False 
     else: 
      print("your current score is:" , score) 

print("game over!! \nYour score is:" , score) 

最後，你不打印出來的分數，詢問用戶是否他們想別的去了，這似乎不可思議尤其是在之前第一個循環。您可以將您的打印語句移動到其他位置之外：

from random import randint 
game = True 
score = 0 

while game == True: 
    die1 = randint(1,6) 
    die2 = randint(1,6) 
    if die1 == die2: 
     score = 0 
     game = False 
    else: 
     score = score + die1 + die2 
     print("your current score is:" , score) 
     goagain = input("do you want another go? Y or N") 
     if goagain == "N" or goagain == "n": 
      game = False 

print("game over!! \nYour score is:" , score)
