Python中提取指定字符串

Python中提取指定字符串，从一个字符串中提取<>里面的内容，整理了两种实现方式，后续有更多的实现方式继续更新
代码如下：

#coding:utf8import reimport sysreload(sys)sys.setdefaultencoding('utf8')#!/usr/bin/pythontemplate = "我要<歌手名>的<歌曲名>"def subString1(template):    copy = False    finished = False    slotList = []    str = ""    for s in template:        if s=='<':            copy = True        elif s=='>':            copy = False            finished = True        elif copy:            str = str+s        if finished:            slotList.append(str)            str = ""            finished = False    return slotListdef subString2(template):    rule = r'<(.*?)>'    slotList = re.findall(rule, template)    return slotListslotList = subString1(template)for slot in slotList:    print slotslotList = subString2(template)for slot in slotList:    print slot
