*  urlparse
 *   *  ParseResult对象

# urlparse #

导入：

> from urllib.parse import urlparse

*  urllib.parse.urlparse(urlstring, scheme=’’, allow\_fragments=True)->ParseResult \#将url解析为6个组件。
    
     *  urlstring \#需要解析的url字符串
     *  scheme \#寻址方案。
     *  fragments \#如果allow\_fragments参数为false，则不能识别片段标识符。相反，它们被解析为路径、参数或查询组件的一部分，fragment被设置为返回值中的空字符串。
     *  ParseResult 返回值对象，是一个元组类型的实例。
     *  简单示例
    
        >>> from urllib.parse import urlparse
        >>> o = urlparse('http://www.cwi.nl:80/%7Eguido/Python.html')
        >>> o   # doctest: +NORMALIZE_WHITESPACE
        ParseResult(scheme='http', netloc='www.cwi.nl:80', path='/%7Eguido/Python.html',
                    params='', query='', fragment='')
        >>> o.scheme
        'http'
        >>> o.port
        80
        >>> o.geturl()
        'http://www.cwi.nl:80/%7Eguido/Python.html'

## ParseResult对象 ##

元组子类的一个实例。该类具有以下附加的只读便利属性:
