Question

所以我之前做了这个代码，但是在调用时它不会使用check_level命令或者award命令：

from random import randint

class RPG:
    #Defines parts of your character
    def __init__(self, character_name):
        self.chrn = character_name
        self.exp = 0 #Total Experince points
        self.level = 1 #Total Level
        self.h = 25 #Player Health
        self.expn = 10 #Experience Needed
        self.eh = 10 #Base Enemy Health
        self.set = False #Used to chest enemy status
        self.win = False #Used to check for win

    def set_basic(self): # Sets up the basic enemy.
        if self.eh == 0:
            self.eh = 10

    def check_level(self): # Checks to see if you have enough EXP to level up.
        if self.exp >= self.expn:
            self.level = self.level + 1
            self.exp = 0
            self.expn = self.level * 10
            print('Level has increased to {0}'.format(self.level))


    def check_enemy(self): # Checks to see if enemy's health is equal to 0.
        if self.eh == 0:
            print('You Win')
            self.set == True
            RPG.set_basic(self)
        else:
            print('')

    def award(self): # Awards EXP if enemy is dead.
        if self.set == True:
            self.exp = self.exp + 5
            print ('You gained 5 EXP!')

    def attack(self): #The main character's attack.
        x = randint(1,100)
        if x > 20:
            y = randint(1, self.level * 3)
            self.eh = self.eh - y
            final = ('Enemy took {0} damage'.format(y))
            print(final)
            if self.eh < 0:
                self.eh = 0
            print('Enemy has {0} health left'.format(self.eh))
            print('')
            RPG.check_enemy(self)
            RPG.award(self)
            RPG.check_level(self)
        else:
            print('Miss!')

Answer 1

此：

RPG.check_enemy(self)
RPG.award(self)
RPG.check_level(self)

应该是：

self.check_enemy()
self.award()
self.check_level()

暗示self param。

编辑：实际上您的任何RPG.*(self)函数都应该是self.*() - 我看到其中有一些函数散布在整个课程中。

Answer 2

Samsquanch将您的所有RPG.(self)方法调用更改为self.*()是正确的。当您调用方法时，python将始终将实例对象作为第一个参数传递。这样您就可以避免像以前一样显式调用该方法。您可以查看this link以获取有关self。

我测试了您的代码，看起来您的问题在check_enemy()内。您需要将self.set == True更改为self.set = True。

新方法应如下所示

def check_enemy(self):
    if self.eh == 0:
        print('You Win')
        self.set = True
        self.set_basic()
    else:
        print('')

Python类不会执行我的函数
