Python 名称错误：名称'；自我'；尝试创建模块时未定义

我有两个文件

检查.py

import UrlParsing as owm

API_key = 'private_API_Key'

obj1 = owm.OWM(API_key)
cd = obj1.three_hours_forecast("London, uk")
print(cd)

import urllib

和UrlParsing.py

print(cd)

        data_dictionary = get_dict(api_url)
        return data_dictionary

    def get_dict(self, api_url):
        url = urllib.urlopen(api_url)
        output_data = url.read().decode('utf-8')
        data_dict = json.loads(output_data)
        url.close()
        print(data_dict)
        return data_dict

cd = obj1.three_hours_forecast("London", "uk")

def three_hours_forecast(self, city, country):
        cty = city
        api_url = "http://api.openweathermap.org/data/2.5/forecast?q={},{}&mode=json&units=metric&APPID={}".format(cty, country, self.API_key)
        data_dictionary = get_dict(api_url)
        return data_dictionary

我正在尝试创建一个UrlParsing模块，以便在主程序中使用它。谁能告诉我这个程序有什么问题吗。我收到名称错误：未定义名称“self”

我做错了什么？你能告诉我怎么改正吗。我试着对同样的问题做一些跟进，但没有成功。谢谢你的帮助

错误跟踪到这一行

        api_url = "http://api.openweathermap.org/data/2.5/forecast?q={},{}&mode=json&units=metric&APPID={}".format(cty, country, self.API_key)

我希望这对你有帮助

您没有将

self

作为

three\u hours\u forecast

的第一个参数传入

three\u hours\u forecast

中，您忘记了

self

参数，你忘了把self.放在函数中的get_dict.调用中。当我尝试这样做时，它是说很少有参数被称为抛出错误。你是否尝试过定义三小时预测（self，city，country）？在这行：

cd=obj1.三小时预测（“伦敦，英国”）

您在同一参数中传递的是城市和国家。。尝试：

cd=obj1.三小时预测（“伦敦”、“英国”）

您没有将

self

作为

三小时预测的第一个参数传递给
self
您忘记了
三小时预测中的
self
参数，你忘了把self.
放在函数中的get_dict.
