基本 Python while/for question。 無法跳出循環

Question

每個 function 都在工作，但不能完全擺脫整個 function。即使我使用 break，也有一些東西不工作。 請幫忙。

def start():
    wizard = "Wizard"
   elf = "Elf"   
   human = "Human"
   orc = "Orc"

   wizard_hp = 70
   elf_hp = 100
   human_hp = 150
   orc_hp = 400

   wizard_damage = 150
   elf_damage = 100
   human_damage = 20
   orc_damage = 200

   dragon_hp = 300
   dragon_damage = 50

   while True:
  
       print("✰✰ Welcome to the game ✰✰\n")
       print("1)   Wizard ")
       print("2)   Elf ")
       print("3)   Human ")
       print("4)   Orc ")

       character = input("Choose your character: ").lower()

       if character == "1" or character == "wizard":
           character = wizard
           my_hp = wizard_hp
           my_damage = wizard_damage
           break
       elif character == "2" or character == "elf":
           character = elf
           my_hp = elf_hp
           my_damage = elf_damage
           break
       elif character == "3" or character == "human":
           character = human
           my_hp = human_hp
           my_damage = human_damage
           break
       elif character == "4" or character == "orc":
           character = orc
           my_hp = orc_hp
           my_damage = orc_damage
           break
       else:
           print("\n- Unknown Character \n")
       break

   print("\nYou have chosen the character: ", character)
   print("\n- Health: ", my_hp)
   print("- Damage: ", my_damage, "\n")

   while True:
  
       dragon_hp =- my_damage
       print("The", character, "damaged the Dragon!")
       print(f"The {character}'s hitpoints are now: {my_hp} \n")
       if dragon_hp <= 0:
           print("The Dragon has lost the battle", "\n")
      
       my_hp =- dragon_damage
       print("The Dragon strikes back at", character)
       print("The Dragon's hitpoints are now: ", dragon_hp, "\n")
       if my_hp <= 0:
           print("You have lost your battle! ", "\n")
    
       play_again = input("Do you want to play again? Type Yes or No: ").lower()
  
       while True:
         if play_again == "1" or "yes":
             print("\n") # even if you only put start(); on line 80, the line 81 and 83 is reading line 80(start(;)) for some reasons
             start();   
         elif play_again == "2" or "no":
             break
         else:
             break
       break   
start();

這只是基本的 python 東西，我正試圖開始。 我知道我錯過了一件小事，但安靜無法得到結果。

在最后一個 while 循環中，它有它的評論。 請閱讀它以獲得額外的解釋

Answer 1

兩個不同的東西：

1. 您最后的邏輯實際上總是True因為您忘記添加or play_again == "yes 。
2. 現在，您的游戲會詢問用戶是否想在每一回合后再次玩游戲。 你的再次玩的檢查應該被選中，這樣它只在游戲玩完后執行一次，而不是每次都執行。

當您比較語句時，Python 將嘗試使您的值成為布爾值。 因此，它將執行bool(insert-statement-here) 。 所以，最后，你的比較， if play_again == "1" or "yes":實際上是兩部分。

bool(if play_again == "1") - 這有一個值。 這取決於他們是否再次播放。

bool("yes") - 這總是正確的。 由於這始終為真，因此您的代碼將始終進入此塊。

你的頭在正確的地方，你應該這樣做：

if play_again == "1" or play_again == "yes":
    print("\n")  # even if you only put start(); on line 80, the line 81 and 83 is reading line 80(start(;)) for some reasons
elif play_again == "2" or play_again == "no":
    break
else:
    break

我認為您也在向后顯示健康狀況。 巨龍攻擊后，你應該顯示角色的生命值，而不是巨龍的生命值。 這是一個很長的答案，但我認為它可以解決您遇到的幾個問題。 你肯定非常接近，但試着放慢一點。 您的代碼只會像您對問題的想法一樣清晰 - 不會更多。 你只需要游戲的播放時間是真實的，其他一切都只是配置，可以在游戲開始時預先完成。 “玩游戲”——也就是“破壞性的來回走動”是這期間唯一需要做的事情。

def start():
    wizard = "Wizard"

    dragon_hp = 300
    dragon_damage = 50

    print("✰✰ Welcome to the game ✰✰\n")

        start()
