2.JAVA正則表達(dá)式匹配解取，替換，查找禀苦，切割
4.命名捕獲組
python 正則寫(xiě)法示例如下：
import re
if __name__ =='__main__':
print('start>>>>')
regex_start_end =r'(?P<go>#TIME\d#)去，(?P<return>#TIME\d#)回來(lái)';
sentence ="#TIME0#去振乏，#TIME1#回來(lái)";
temp = re.match(regex_start_end, sentence)
a = temp.group("go")
b = temp.group("return")
print (a)
print (b)
