Python 名称错误：名称'；countrychoice&x27；没有定义

我正在写的程序有点问题

我让用户输入一个国家，然后输入该国的一个城市，然后使用API查看所选城市的天气预报

我正在使用一个类，如下所示：

class requestChoice:

    def __init__(self):
        self.countrychoice = None
        self.citychoice = None

    def countryChoice(self):
        self.countrychoice = input("Enter which country your city is in(in english): ")

    def cityChoice(self):
        self.citychoice = input("Enter the name of the city: ")

from requestchoice import requestChoice

import requests

if __name__ == '__main__':
    """Introducion"""
    print ("\nThis program lets you see a weather forecast for your choosen city.")

rc = requestChoice()
while True:
    print("\nWhen you have typed in country and city, press 3 in the menu to see the weather forecast for your choice.\n")
    menu = input("\nPress 1 for contry\nPress 2 for city\nPress 3 to see forecast\nPress 4 to exit\n")
    if menu == "1":
        rc.countryChoice()
    elif menu == "2":
        rc.cityChoice()
    elif menu == "3":
        r = requests.get("http://api.wunderground.com/api/0def10027afaebb7/forecast/q/" + countrychoice + "/" + citychoice + ".json")
        data = r.json()
        try:
            for day in data['forecast']['simpleforecast']['forecastday']:
                print (day['date']['weekday'] + ":")
                print ("Conditions: ", day['conditions'])
                print ("High: ", day['high']['celsius'] + "C", '\n' "Low: ", day['low']['celsius'] + "C", '\n')
        except Exception as e:
            print ("\nHave you typed in the correct country and city?\nBecause we got a" ,e, "error")
    else: 
        print ("\nGoodbye")
        break

我的主要程序如下所示：

class requestChoice:

    def __init__(self):
        self.countrychoice = None
        self.citychoice = None

    def countryChoice(self):
        self.countrychoice = input("Enter which country your city is in(in english): ")

    def cityChoice(self):
        self.citychoice = input("Enter the name of the city: ")

from requestchoice import requestChoice

import requests

if __name__ == '__main__':
    """Introducion"""
    print ("\nThis program lets you see a weather forecast for your choosen city.")

rc = requestChoice()
while True:
    print("\nWhen you have typed in country and city, press 3 in the menu to see the weather forecast for your choice.\n")
    menu = input("\nPress 1 for contry\nPress 2 for city\nPress 3 to see forecast\nPress 4 to exit\n")
    if menu == "1":
        rc.countryChoice()
    elif menu == "2":
        rc.cityChoice()
    elif menu == "3":
        r = requests.get("http://api.wunderground.com/api/0def10027afaebb7/forecast/q/" + countrychoice + "/" + citychoice + ".json")
        data = r.json()
        try:
            for day in data['forecast']['simpleforecast']['forecastday']:
                print (day['date']['weekday'] + ":")
                print ("Conditions: ", day['conditions'])
                print ("High: ", day['high']['celsius'] + "C", '\n' "Low: ", day['low']['celsius'] + "C", '\n')
        except Exception as e:
            print ("\nHave you typed in the correct country and city?\nBecause we got a" ,e, "error")
    else: 
        print ("\nGoodbye")
        break

当我运行我的程序时，我得到一个错误

NameError:name'countrychoice'未定义

。

citychoice

也会出现同样的错误。我尝试在我的课堂上创建一个列表，并将

countrychoice

附加到列表中，但没有成功。我应该如何使它按预期工作？

您必须使用相应的对象名称访问它们。在这种情况下

rc.countrychoice
rc.citychoice

那么这条线

r = requests.get("http://api.wunderground.com/api/0def10027afaebb7/forecast/q/" + countrychoice + "/" + citychoice + ".json")

变成

r = requests.get("http://api.wunderground.com/api/0def10027afaebb7/forecast/q/" + rc.countrychoice + "/" + rc.citychoice + ".json")
