怎么用python输出当前日期星期几

Python中获取日期的方法

fromdatetimeimportdatetime,date

dayOfWeek=datetime.now().weekday()

python获取今日日期

importdatetime
today=datetime.date.today()
print(today)

输出：2019-06-25

python获取昨日日期

importdatetime
today=datetime.date.today()
zuotian=today-datetime.timedelta(days=1)
print(zuotian)
