Use:
用：
from datetime import datetime
today = datetime.today()
datem = datetime(today.year, today.month, 1)
I assume you want the first of the month.
我假设您想要本月的第一天。

Try this solution:
试试这个解决方案：
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

You can always use a sub-string method:
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]);
This will get you the current month and year in integer format. If you want them to be strings you simply have to remove the " int " precedence while assigning values to the variables curr_yearand curr_month.
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.

Use:
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：8.1.7。strftime() 和 strptime() 行为

The above things are useful for any date parsing, not only now or today. It can be useful for any date parsing.
以上内容对任何日期解析都很有用，不仅是现在或今天。它可用于任何日期解析。
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')
And so on...
等等...
