日期时间当前年和月python

Question

我必须在日期时间有当前年份和月份.我用这个:

datem = datetime.today().strftime("%Y-%m")
datem = datetime.strptime(datem, "%Y-%m")

也许有另一种方式？

Answer 1

尝试此解决方案:

from datetime import datetime

currentSecond= datetime.now().second
currentMinute = datetime.now().minute
currentHour = datetime.now().hour

currentDay = datetime.now().day
currentMonth = datetime.now().month
currentYear = datetime.now().year

Answer 2

怎么样

today = datetime.today()
datem = datetime(today.year, today.month, 1)

我假设你想要这个月的第一天.

Answer 3

我来不及但是有人会发现这对将来很有用.

from datetime import datetime

current_month = datetime.now().strftime('%m') // 02 //This is 0 padded
current_month_text = datetime.now().strftime('%h') // Feb
current_month_text = datetime.now().strftime('%B') // February

current_day = datetime.now().strftime('%d')   // 23 //This is also padded
current_day_text = datetime.now().strftime('%a')  // Fri
current_day_full_text = datetime.now().strftime('%A')  // Friday

current_weekday_day_of_today = datetime.now().strftime('%w') //5  Where 0 is Sunday and 6 is Saturday.

current_year_full = datetime.now().strftime('%Y')  // 2018
current_year_short = datetime.now().strftime('%y')  // 18 without century

current_second= datetime.now().strftime('%S') //53
current_minute = datetime.now().strftime('%M') //38
current_hour = datetime.now().strftime('%H') //16 like 4pm
current_hour = datetime.now().strftime('%I') // 04 pm

current_hour_am_pm = datetime.now().strftime('%p') // 4 pm

current_microseconds = datetime.now().strftime('%f') // 623596 Rarely we need.

current_timzone = datetime.now().strftime('%Z') // UTC, EST, CST etc. (empty string if the object is naive).

参考:https://docs.python.org/2/library/datetime.html#strftime-and-strptime-behavior

参考:https://docs.python.org/3/library/datetime.html#strftime-and-strptime-behavior

以上内容对于现在或今天解析的任何日期都很有用,它可以用于任何日期解析.

e.g.
my_date = "23-02-2018 00:00:00"

datetime.strptime(str(my_date),'%d-%m-%Y %H:%M:%S').strftime('%Y-%m-%d %H:%M:%S+00:00')

datetime.strptime(str(my_date),'%d-%m-%Y %H:%M:%S').strftime('%m')

等等....

希望有人觉得这很有用.

Answer 4

>>> from datetime import date
>>> date.today().month
2
>>> date.today().year
2020
>>> date.today().day
13

Answer 5

您始终可以使用子字符串方法：

import datetime;

today = str(datetime.date.today());
curr_year = int(today[:4]);
curr_month = int(today[5:7]);

这将为您提供整数格式的当前月份和年份。如果您希望它们是字符串，您只需在为变量curr_year和curr_month.

Answer 6

迟到的答案，但您也可以使用：

import time
ym = time.strftime("%Y-%m")

Answer 7

您可以使用以下命令将接受的答案写成单行date.replace：

datem = datetime.today().replace(day=1)

Answer 8

该问题要求专门使用日期时间。

这是一种仅使用日期时间的方式：

from datetime import datetime
year = datetime.now().year
month = datetime.now().month
