本文利用Python计算今天日期、明天日期、和昨天日期的相关方法,及获取当前日期是星期几。
python编程操作日期时间主要用到的python模块是datetime和time这2个模块
获取星期几
from datetime import datetime, date dayOfWeek = datetime.now().weekday() print(dayOfWeek) dayOfWeek = datetime.today().weekday() print(dayOfWeek)
注意:datetime类的weekday()方法可以获得datetime是星期几,注意weekday()返回的是0~6,是星期一到星期日。
python获取今日日期
import datetime today = datetime.date.today() print(today)
输出:2019-06-25
python获取昨日日期
import datetime today = datetime.date.today() zuotian = today- datetime.timedelta(days=1) print(zuotian)
获取明天日期
import datetime today = datetime.date.today() tomorrow = today + datetime.timedelta(days=1) print(tomorrow)
获取后天日期
import datetime today = datetime.date.today() tomorrow = today + datetime.timedelta(days=2) print(tomorrow)
小结:不管是往前计算还是往后计算,直接在今日日期上进行天数的相加减
