请输入城市:成都
Traceback (most recent call last):

我跟鱼C一样 改了之后 为什么又有错误 也没搞懂哪里有错

以下是代码：

import urllib.request
import json
import pickle

pickle_file = open('city_data.pkl','rb')
city = pickle.load(pickle_file)

password=input('请输入城市:')
name1=city[password]
File1 =urllib.request.urlopen('http://m.weather.com.cn/data/'+name1+'.html')
weatherHTML= File1.read().decode('utf-8')
weatherJSON = json.JSONDecoder().decode(weatherHTML)
weatherInfo = weatherJSON['weatherinfo']
print ( '城市：', weatherInfo['city'])
print ('时间：', weatherInfo['date_y'])
print ( '24小时天气：')
print ('温度：', weatherInfo['temp1'])
print ('天气：', weatherInfo['weather1'])
print ('风速：', weatherInfo['wind1'])
print ('紫外线：', weatherInfo['index_uv'])
print ('穿衣指数：', weatherInfo['index_d'])
print ('48小时天气：')
print ('温度：', weatherInfo['temp2'])
print ('天气：', weatherInfo['weather2'])
print ('风速：', weatherInfo['wind2'])
print ('紫外线：', weatherInfo['index48_uv'])
print ('穿衣指数：', weatherInfo['index48_d'])
print ('72小时天气：')
print ('温度：', weatherInfo['temp3'])
print ('天气：', weatherInfo['weather3'])
print ('风速：', weatherInfo['wind3'])
input ('按任意键退出：')

我之前的pkl文件与天气脚本的文件不在同一个文件夹，后面我改过去以后 发现还是报错

求解答！！！
