python - 提取字符串 split() 操作产生的单个项目

Question

a = line.splitlines()[:2]

我得到的输出如下所示。

['GET /en/html/dummy.php?name=MyName&married=not+single &male=yes HTTP/1.1']
['Host: www.explainth.at']
['User-Agent: Mozilla/5.0 (Windows;en-GB; rv:1.8.0.11) Gecko/20070312 Firefox/1.5.0.11']
['Accept: text/xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5']
['Accept-Language: en-gb,en;q=0.5']
['Accept-Encoding: gzip,deflate']
['Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7']
['Keep-Alive: 300']

我想获得前两项:

GET /en/html/dummy.php?name=MyName&married=not+single &male=yes HTTP/1.1
Host: www.explainth.at

Answer 1
