import
time,datetime
def
get_week_day(date):
week_day_dict
=
{
0
:
'星期一'
,
1
:
'星期二'
,
2
:
'星期三'
,
3
:
'星期四'
,
4
:
'星期五'
,
5
:
'星期六'
,
6
:
'星期天'
,
}
day
=
date.weekday()
return
week_day_dict[day]
print
(get_week_day(datetime.datetime.now()))
|
輸出結果為：星期一
進一步應用：
today = datetime.date.today()
yesterday = today - datetime.timedelta(days=1)
#獲取昨天是星期幾
thistime=yesterday.isoweekday()
if thistime==1:
a="周一"
elif thistime==2:
a="周二"
elif thistime==3:
a="周三"
elif thistime==4:
a="周四"
elif thistime==5:
a="周五"
elif thistime==6:
a="周六"
elif thistime==7:
a="周日"
print(a)
