现如今有一组新的秒表数据，需要对其数据进行提取
sarah.txt
sara,2002-9-9,2:58,2.58,2:39,2-25,2-55,2:54,2.18,2:55,2:55
1.将sarah.txt中的名字与成绩打印出来（使用读取文件的方式）
#coding=utf-8#打印出秒表数据的姓名与前三列的成绩def get_file(filename): try:
with open(filename) as f:
data=f.readline().strip().split(",") return data except IOError as e: raise edef qxsj(time_string): if "-" in time_string:
splitter="-"
elif ":" in time_string:
splitter=":"
else: return time_string
(fen,miao)=time_string.strip().split(splitter)
