我正在编写的当前程序有一些问题。
我让用户输入一个国家，然后输入那个国家的城市，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: ")
我的主程序如下所示：
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，我得到了错误NameError: name 'countrychoice' is not defined。这将是相同的错误citychoice。我尝试在我的班级中创建一个列表并将其附加countrychoice到列表中，但没有任何运气。我应该如何让它如愿工作？
