python 字符串和时间格式(datetime)相互转换-

-03-17 11：00：00格式转化

import datetime# str转时间格式：dd = '-03-17 11:00:00' dd = datetime.datetime.strptime(dd, "%Y-%m-%d %H:%M:%S") print(dd,type(dd)) # 时间格式转str: dc = dd.strftime("%Y-%m-%d %H:%M:%S") print(dc,type(dc))

输出：-03-17 11:00:00 <class 'datetime.datetime'>

-03-17 11:00:00 <class 'str'>

0616格式转化

# str转时间格式：dd = '0317'dd = datetime.datetime.strptime(dd, "%Y%m%d")print(dd,type(dd))# 时间格式转str:dc = dd.strftime("%Y%m%d")print(dc,type(dc))

注：-03-17转化成0317

startDate="-06-16"startDate=startDate.replace("-","")print(startDate)
