你可以使用这个类:

import time 

import datetime

class TimingClass():

    def __init__(self):

        self.YEAR        = datetime.date.today().year
        self.MONTH       = datetime.date.today().month
        self.DATE        = datetime.date.today().day
        self.HOUR        = datetime.datetime.now().hour
        self.MINUTE      = datetime.datetime.now().minute
        self.SECONDS     = datetime.datetime.now().second
        
        self.TODAY       = datetime.date.today()
        self.YESTERDAY   = datetime.datetime.strftime( (self.TODAY - datetime.timedelta(days = 1)) , '%Y-%m-%d')
        self.TOMORROW   = datetime.datetime.strftime( (self.TODAY + datetime.timedelta(days = 1)) , '%Y-%m-%d')
        
        self.TODAY_datetime = datetime.datetime.combine(datetime.date.today(), datetime.datetime.min.time())

一种从日期转换到日期时间的方法还没有提到:

from datetime import date, datetime
d = date.today()
datetime.strptime(d.strftime('%Y%m%d'), '%Y%m%d')

你也可以使用

date = datetime.utcnow().date()
dt = datetime.fromisoformat(date.isoformat())

print(dt)

datetime.datetime(2021, 11, 15, 0, 0)

你可以使用这个类:

import time 

import datetime

class TimingClass():

    def __init__(self):

        self.YEAR        = datetime.date.today().year
        self.MONTH       = datetime.date.today().month
        self.DATE        = datetime.date.today().day
        self.HOUR        = datetime.datetime.now().hour
        self.MINUTE      = datetime.datetime.now().minute
        self.SECONDS     = datetime.datetime.now().second
        
        self.TODAY       = datetime.date.today()
        self.YESTERDAY   = datetime.datetime.strftime( (self.TODAY - datetime.timedelta(days = 1)) , '%Y-%m-%d')
        self.TOMORROW   = datetime.datetime.strftime( (self.TODAY + datetime.timedelta(days = 1)) , '%Y-%m-%d')
        
        self.TODAY_datetime = datetime.datetime.combine(datetime.date.today(), datetime.datetime.min.time())

我真的需要手动调用datetime(d。年，月，日)

不，你更想打电话

date_to_datetime(dt)

你可以在项目中的一些utils/time.py中实现一次:

from typing import Optional
from datetime import date, datetime

def date_to_datetime(
    dt: date,
    hour: Optional[int] = 0,
    minute: Optional[int] = 0, 
    second: Optional[int] = 0) -> datetime:

    return datetime(dt.year, dt.month, dt.day, hour, minute, second)

你可以使用datetime.combine(date, time);对于时间，您创建了一个datetime。时间对象初始化为午夜。

from datetime import date
from datetime import datetime

dt = datetime.combine(date.today(), datetime.min.time())
