Python转换时间戳为指定格式日期

import time
# 获得当前时间时间戳
now = int(time.time())
#转换为其他日期格式,如:"%Y-%m-%d %H:%M:%S"
timeArray = time.localtime(now)
otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray)
print(otherStyleTime)

import datetime
# 获得当前时间
now = datetime.datetime.now()
# 转换为指定的格式
otherStyleTime = now.strftime("%Y-%m-%d %H:%M:%S")
print(otherStyleTime)

import time
timeStamp = 1557502800
timeArray = time.localtime(timeStamp)
otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray)
print(otherStyleTime)

import datetime
timeStamp = 1557502800
dateArray = datetime.datetime.utcfromtimestamp(timeStamp)
otherStyleTime = dateArray.strftime("%Y-%m-%d %H:%M:%S")
print(otherStyleTime)
