Question

我正在尝试从城镇获取天气信息，并从该列表中打印出2个项目。但是，当我尝试运行代码时，我收到此错误：

Traceback (most recent call last): 
    File "/home/pi/Desktop/python/PyWeather.py" line 4, in <module>
        bostonweather = pywapi.get_weather_from_weather_com('UKXX1701', units = 'metric')
    File "/home/pi/Desktop/python/pywapi.py" line 239, in get_weather_from_weather_com
        'wind')[0].getElementsByTagName(tag2)[0].firstChild.data
AtrributeError: 'NoneType' object has no attribute 'data'

这是我的代码：

import pywapi
import string

bostonweather = pywapi.get_weather_from_weather_com('UKXX1701', 'metric')
print ("In Boston, Lincolnshire it is currently: ") + string.ascii_lowercase(bostonweather['current_conditions']['text'] + (" and ") + string.ascii_lowercase(bostonweather['current_conditions']['temperature'] + ("C.\n"))

// EDIT

我刚刚重新启动了我的程序，它只是抛出了一个＆＃34; TypeError：＆＃39; str＆＃39;对象不可调用＆＃34;而是错误。
错误讯息：

Traceback (most recent call last):
    File "/home/pi/Desktop/python/PyWeather.py" line 5, in <module>  
       print ("In Boston, Lincolnshire it is currently: ") + string.ascii_lowercase(bostonweather['current_conditions']['text'] + (" and ") + string.ascii_lowercase(bostonweather['current_conditions']['temperature'] + ("C.\n"))
TypeError: 'str' object is not callable

有关做什么的任何线索？

Answer 1

您正试图致电string.lowercase(blabla)以及您获得TypeError

的地方

你应该做

print "In Boston, Lincolnshire it is currently: " + bostonweather['current_conditions']['text'].lower() + " and " + bostonweather['current_conditions']['temperature'].lower() + ("C.\n")

Answer 2

在打印之前尝试制作所有字符串

import pywapi

bostonweather = pywapi.get_weather_from_weather_com('UKXX1701', 'metric')
print ("In Boston, Lincolnshire it is currently: " + str(bostonweather['current_conditions']['text']).lower() + " and " + str(bostonweather['current_conditions']['temperature']).lower())

AtrributeError：'NoneType'对象没有属性'data'＆amp; TypeError：'str'对象不可调用
