find_all(‘a’)函数是查找所有< a>标签,并通过for循环输出结果;第二个for循环是通过“link.get(‘href’)”代码获取超链接标签中的url网址。 比如“< a class=“poet” href=“http://example.com/dufu” id=“link1”>杜甫< /a>”,通过调用find_all(‘a’)函数获取所有超链接的HTML源码,再调用get(...
file_object = open(file_name, [,access_mode][, buffering]) file_name:字符串类型的文件名称 access_mode:打开文件的模式,下面会详细介绍可取值 buffering:如果该值为0,这不会有寄存;如果其值为1,访问文件时会寄存行;如果其值大于1,表明了这就是寄存区的缓冲大小;如果为负值,寄存去的缓冲大小为系统默认。
