如何从utcnow中提取日，月和年？

Question

我有以下var：time_created = datetime.utcnow()

如何从time_created_day创建仅包含Y，M，d的time_created变量

喜欢这个datetime.datetime(2017, 11, 7)

我有以下解决方案：

from datetime import date

time_created_day = date(time_created.year, time_created.month, time_created. day)

这是最好的方式吗？

Answer 1

使用datetime.utcnow().date()

datetime.utcnow().date()
datetime.date(2017, 11, 7)

添加回答

datetime对象始终包含年，月，日以及小时，分钟，秒和微秒。它是日期和时间对象包含的内容的组合，请参阅datetime Objects

from datetime import datetime

# this is your datetime object
time_created = datetime.utcnow()

# when you want to see it formatted as Y,M,D call the date method
date_created = time_created.date()

time_created
date_created

输出：

datetime.datetime(2017, 11, 7, 23, 43, 43, 761750)
datetime.date(2017, 11, 7)`

Answer 2

使用time_created.day查找当天。

time_created_day = time_created.day

（月和年类似）

Answer 3

这里对你来说最简单

var dateObj = new Date();
var month = dateObj.getUTCMonth() + 1; //months from 1-12
var day = dateObj.getUTCDate();
var year = dateObj.getUTCFullYear();

newdate = year + " " + month + " " + day;
