Question

我遇到一个问题，即调用要在类“山”中的定义中添加的变量。它运行错误：

属性错误：＆＃39;功能＆＃39;对象没有属性＆＃39;图片＆＃39;

以下是代码：

import random
class currencies:
    film = 5
class pictures:
    picture = {"m_goat": 0, "b_eagle": 0, "marmot": 0, "r_snake": 0, "m_lion": 0, "b_dragon": 0, "vulture": 0}
class location:
    city = True
    shop = False
    mountains = False
    desert = False
class mountain:
    #Travel to mountains
    def travel_m():
        print("You climb to the top of a tall mountain")
        location.mountains = True
        animals = ["mountain goat", "bald eagle", "marmot", "rattlesnake", "mountain lion"]
    animal_pics = ["m_goat", "b_eagle", "marmot", "r_snake", "m_lion"]
    if 1 == 1: #for simplicity I changed this to a non random number
        animal = random.randint(0, 4)
        str_animal = animals[animal]
        ans = input("You see a wild " + str_animal + ". Would you like to take a photo? (y/n) \n")
        if ans == "y" and currencies.film == 0:
            print("You cannot take a picture of this animal because you are out of film")
        elif ans == "y":
            currencies.film -= 1
            pictures.picture[animal_pics] = pictures.picture[animal_pics] + 1 #this is the line with the error
            print("You took a picture of the animal")
        elif ans == "n":
            print("The animal was left unbothered")
        else:
            print("I do not recognize that command")  
def pictures():
    print("You have " + str(pictures.pictures['m_goat']) + " picture(s) of mountain goats")
    print("You have " + str(pictures.pictures['b_eagle']) + " picture(s) of bald eagles")
    print("You have " + str(pictures.pictures['marmot']) + " picture(s) of marmots")
    print("You have " + str(pictures.pictures['r_snake']) + " picture(s) of rattlesnakes")
    print("You have " + str(pictures.pictures['m_lion']) + " picture(s) of mountain lions")
    mountain.travel_m()

感谢您提供任何帮助。我只是在学习这门语言，但我和我的老师都无法在网上找到答案。如果它是愚蠢的，请说

当你这样做时：

def pictures():

您正在重新定义变量pictures。它现在命名函数，而不是之前定义的类。

为函数指定一个与类不冲突的名称，例如

def show_pictures():

此外，在最后一个功能中使用pictures.pictures。那应该是pictures.picture。

修正后，这一行是错误的：

pictures.picture[animal_pics] = pictures.picture[animal_pics] + 1

animal_pics是一个列表，您不能将其用作字典键。我想你的意思是：

pictures.picture[str_animal] += 1

找不到错误：从库中调用项目
