访问函数中创建的python对象，函数外部

我不知道是否有办法做到这一点。我试图仅在满足特定条件时创建对象。 我可以用if语句创建对象，但我不知道如何在以后的代码中使用它。我应该使用“全局”吗？我不确定，因为如果每个if/elif语句都使用相同的对象名

这是第一部分

def dm_roll():
  roll = random.randint(1, 20)
  print(roll)
  if roll > 0 and roll <= 10:
    opponent = Monster('Goblin', 6, 2)
  elif roll > 10 and roll <= 16:
    opponent = Monster('Zombie', 8, 3)
  elif roll > 16 and roll <= 19:
    opponent = Monster('Ogre', 15, 5)
  else:
    opponent = Monster('Dragon', 1000000, 10)

  print("You have run into a {}!".format(opponent.name))

我的问题是目前无法使用随机生成的对象。

有什么想法吗？

您需要编写一个主脚本，其中需要传递对手变量，如下所示：

def dm_roll():
  roll = random.randint(1, 20)
  print(roll)
  if roll > 0 and roll <= 10:
    opponent = Monster('Goblin', 6, 2)
  elif roll > 10 and roll <= 16:
    opponent = Monster('Zombie', 8, 3)
  elif roll > 16 and roll <= 19:
    opponent = Monster('Ogre', 15, 5)
  else:
    opponent = Monster('Dragon', 1000000, 10)
  return opponent   #you need to return the opponent


def fight(opponent,hero):
  # Takes in the opponent and hero
  while opponent.alive() and hero.alive():
    hero.print_status()
    opponent.print_status()

def createHero():
  hero= Hero("<Hero Parameter">) #create hero object as per the conditions you might have
  return hero

if __name__="__main__":
  opponent = dm_roll() # returns the Monster object
  print("You have run into a {}!".format(opponent.name))
  hero = createHero() #returns the Hero Object
  fight(opponent,hero) #Let them fight

def dm_roll（）：
roll=random.randint（1,20）
打印（卷）
如果掷骰>0，掷骰10，掷骰16，掷骰）#根据可能的条件创建英雄对象
回归英雄
如果_name__=“_main__”：
对手=dm_roll（）#返回怪物对象
打印（“您遇到了{}！”格式（对手名称））
hero=createHero（）#返回hero对象
战斗（对手、英雄）#让他们战斗

不必要地使用全局变量不是一个好的做法。您应该返回您可能需要的任何对象，不要使用全局变量

def dm_roll():
  roll = random.randint(1, 20)
  print(roll)
  if roll > 0 and roll <= 10:
    opponent = Monster('Goblin', 6, 2)
  elif roll > 10 and roll <= 16:
    opponent = Monster('Zombie', 8, 3)
  elif roll > 16 and roll <= 19:
    opponent = Monster('Ogre', 15, 5)
  else:
    opponent = Monster('Dragon', 1000000, 10)
  return opponent   #you need to return the opponent


def fight(opponent,hero):
  # Takes in the opponent and hero
  while opponent.alive() and hero.alive():
    hero.print_status()
    opponent.print_status()

def createHero():
  hero= Hero("<Hero Parameter">) #create hero object as per the conditions you might have
  return hero

if __name__="__main__":
  opponent = dm_roll() # returns the Monster object
  print("You have run into a {}!".format(opponent.name))
  hero = createHero() #returns the Hero Object
  fight(opponent,hero) #Let them fight
