python 字符串和时间格式(datetime)相互转换-
2019-03-17 11:00:00格式转化
import datetime
# str转时间格式:
dd = '2019-03-17 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:2019-03-17 11:00:00 <class 'datetime.datetime'>
2019-03-17 11:00:00 <class 'str'>
20190616格式转化
# str转时间格式: dd = '20190317' 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:2019-03-17转化成20190317
startDate="2019-06-16" startDate=startDate.replace("-","") print(startDate)
