为什么课上下载的源代码在pycharm上面运行就不行了呢？


python小白找不出错误！



直接下载源代码运行后的结果如下：

请输入城市:汕头
Traceback (most recent call last):
  File "D:/Desktop/小甲鱼/31-40源代码/天气查询课件源代码.py", line 2452, in <module>
    File1 =urllib.request.urlopen('http://m.weather.com.cn/data/'+name1+'.html')#打开url
  File "D:\python\lib\urllib\request.py", line 223, in urlopen
    return opener.open(url, data, timeout)
  File "D:\python\lib\urllib\request.py", line 532, in open
    response = meth(req, response)
  File "D:\python\lib\urllib\request.py", line 642, in http_response
    'http', request, response, code, msg, hdrs)
  File "D:\python\lib\urllib\request.py", line 570, in error
    return self._call_chain(*args)
  File "D:\python\lib\urllib\request.py", line 504, in _call_chain

爬虫被网站反爬了，需要加上 headers 。（这个知识点等你学到爬虫那块就知道，现在先不用管）

代码发上来，帮你改改。（可能会太长）
