import datetime 

# 先获得时间数组格式的日期

threeDayAgo = (datetime.datetime.now() - datetime.timedelta(days = 3))

# 转换为时间戳

timeStamp = int(time.mktime(threeDayAgo.timetuple()))

# 转换为其他字符串格式

otherStyleTime = threeDayAgo.strftime("%Y-%m-%d %H:%M:%S")

print(otherStyleTime)

import timeimport datetime 

#给定时间戳

timeStamp = 1557502800

dateArray = datetime.datetime.utcfromtimestamp(timeStamp)

threeDayAgo = dateArray - datetime.timedelta(days = 3)

print(threeDayAgo)
