Question

我需要从login（）函数访问_startgame（）函数。我用google搜索没有结果！

import random
import player
#import hashlib
#import :P
import random
import time

gamename = "foobarbaz"

class Player(object):
    def __init__(self, name, maxhp, minhp, maxmana, minmana, maxskill, minskill):
      self.hp = random.randint(minhp, maxhp)
      self.mana = random.randint(minmana, maxmana)
      self.skill = random.randint(minskill, maxskill)
      self.name = name
      #self.race = race
      self.gold = 200 + random.randint(50, 200)
      self.inventory = []


    def check_dead(self):
      if self.hp < 0:
        print ("You Died...")
        self.inventory = []
        self.gold = 0
        return 0
      else:
        return self.hp

def prompt(x):
    print(x.name + ":" + str(x.hp) + " HP")

在Python中，当执行流程离开这样的范围时，在某个范围内创建的所有对象（当然包括函数）都是“垃圾收集”。因此，该函数（_startgame）仅在执行new_player时存在。

你不能将函数或变量绑定到另一个函数，就像将函数或变量绑定到类一样，除非你编写这样的代码：

def bar():
    pass

def foo():
    pass

foo.bar = bar
foo.bar()

解决您的问题：

正如AdamSmith在他的评论中指出的那样，只需创建一个函数（或移动你已经拥有的函数），然后使用create_player函数。

# You need your new function takes three parameters. 
def _startgame(gamename, name, theplayer):
      print("Welcome to " + gamename + " " + name)
      print("To Exit, type exit\nYou can type anywhere you see")
      prompt(theplayer)

然后，你可以在函数new_player（或从任何你想要的地方）调用它，如下所示：

#...
_startgame(gamename, name, theplayer)
#...

直接调用嵌套函数
