python 时间对应计算

import re
import time
def parse_time(date):
    if re.match('刚刚', date):
        date = time.strftime('%Y-%m-%d %H:%M', time.localtime(time.time()))
    if re.match('\d+分钟前', date):
        minute = re.match('(\d+)', date).group()
        date = time.strftime('%Y-%m-%d %H:%M', time.localtime(time.time() - float(minute) * ))
    if re.match('\d+小时前', date):
        hour = re.match('(\d+)', date).group()
        date = time.strftime('%Y-%m-%d %H:%M', time.localtime(time.time() - float(hour) *  * ))
    if re.match('昨天.*', date):
        date = re.match('昨天(.*)', date).group().strip()
        print(date)
        date = time.strftime('%Y-%m-%d', time.localtime(time.time()-  *  * )) + ' ' + date
    if re.match('\d{2}-\d{2}', date):
        date = time.strftime('%Y-', time.localtime()) + date + ' 00:00'
    return date
# print(parse_time('10-05'))
print(time.localtime()) # 当前时间
print(time.strftime('%Y-', time.localtime()))
