获取指定时间三天后的时间戳

import time

# a1 = "2018-01-01 14:00:21"
# # 先转换为时间数组
# timeArray = time.strptime(a1, "%Y-%m-%d %H:%M:%S")
#
# # 转换为时间戳
# timeStamp = int(time.mktime(timeArray))
# print(timeStamp)
#
# # 格式转换 - 转为 /
# a2 = "2018-01-04 14:00:21"
# # 先转换为时间数组,然后转换为其他格式
# timeArray = time.strptime(a2, "%Y/%m/%d %H:%M:%S")
# otherStyleTime = time.strftime("%Y/%m/%d %H:%M:%S", timeArray)
# print(otherStyleTime)
