追加函數變量

Question

我正在創建一個RPG遊戲，其中我使用了一個健康和魔藥功能。在每個敵人遭遇後，玩家失去隨機的健康狀態。如果英雄有藥水離開他們獲得特定的健康。我試圖保存下次遭遇時的健康和藥水量，從上次遇到的健康和藥水是相同的。我如何追加或保存下一輪的變量？這裏是我對這個函數的代碼。

import random 
    health = 20 
    potion = 5 
    playerdamage = random.randint(0, 7) 
    print("\nDuring the fight you took", playerdamage, "damage!") 
    health -= playerdamage 
    if potion > 0: 
     print("You have a health potion to use!") 
     health += 5 
     potion -= 1 
     print("You gained 5 health back and are now at",health,"health!") 
     print("you have", potion, "health potion(s) left!") 
    else: 
     print("You have no health potions left!") 
     print("You have", health, "health left\n") 

    return health 

下面是完整的代碼

有兩個方面考慮這裏：如何組織代碼，以及如何組織數據。要重複「遇到敵人」，請使用子例程（即def語句）。要存儲數據，您有兩種選擇：創建播放器類型或將數據存儲在全局變量中。如果你可以保證遊戲只涉及一個玩家，那麼使用全局變量更容易，但擴展性較差。
要進入全球路線：

import random 
health = 20 
potion = 5 

def encounterEnemy(): 
    playerdamage = random.randint(0, 7) 
    print("\nDuring the fight you took", playerdamage, "damage!") 
    health -= playerdamage 
    if potion > 0: 
     print("You have a health potion to use!") 
     health += 5 
     potion -= 1 
     print("You gained 5 health back and are now at",health,"health!") 
     print("you have", potion, "health potion(s) left!") 
    else: 
     print("You have no health potions left!") 
     print("You have", health, "health left\n") 
    return health 

然後，每次調用encounterEnemy時間，玩家的總生命和藥水將作相應調整。

要創建一個新的數據類型：

import random 
class Player: 
    def __init__(health, potion): 
     self.health = health 
     self.potion = potion 
    def encounterEnemy(): 
     playerdamage = random.randint(0, 7) 
     print("\nDuring the fight you took", playerdamage, "damage!") 
     self.health -= playerdamage 
     if self.potion > 0: 
      print("You have a health potion to use!") 
      self.health += 5 
      self.potion -= 1 
      print("You gained 5 health back and are now at", self.health, "health!") 
      print("you have", self.potion, "health potion(s) left!") 
     else: 
      print("You have no health potions left!") 
      print("You have", self.health, "health left\n") 
     return self.health 

currPlayer = Player(20, 5) 
currPlayer.encounterEnemy() 

創建一個新的數據類型也非常有用，因爲它可以讓你「捆綁」所有的問題關聯在一起的數據。
