如何在Python中只获取匹配的文本？
提问于 2013-02-18 21:00:07
我用Python编写了以下代码
import psutil
import re
_list = psutil.get_pid_list()
for i in _list:
if i > 0:
_process_path = psutil.Process(i).exe
_match = re.search('\/Applications\/.*\.app\/',_process_path)
if _match:
print _process_path它是有效的，下面是它返回结果的一个示例：
/Applications/RegExr.app/Contents/MacOS/RegExr
/Applications/Google Chrome.app/Contents/Versions/24.0.1312.57/Google Chrome Helper.app/Contents/MacOS/Google Chrome Helper
/Applications/TextWrangler.app/Contents/Helpers/Crash Reporter.app/Contents/Helpers/crash-catcher

/Applications/Twitter.app/Contents/MacOS/Twitter
/Applications/ScreenFlow.app/Contents/MacOS/ScreenFlowHelper.app/Contents/MacOS/ScreenFlowHelper我如何让它只返回这个呢？

改为使用MatchObject.group() method打印匹配的组
print _match.group()Stack Overflow用户

您的_match对象可以将匹配的文本作为_match.group(0)返回。
