我有这个字符串:
'2012-02-10' # (year-month-day)
我需要它作为日期类型才能使用日期函数isoweekday()
.
and I need it to be as date type for me to use the date function isoweekday()
.
有谁知道如何将这个字符串转换为日期?
Does anyone know how I can convert this string into a date?
你可以用 datetime.strptime()
例子:
>>> from datetime import datetime
>>> datetime.strptime('2012-02-10' , '%Y-%m-%d')
datetime.datetime(2012, 2, 10, 0, 0)
>>> _.isoweekday()
5
您可以找到包含所有 strptime
指令的表 这里.
You can find the table with all the strptime
directive here.
如果 .isweekday() == 6
增加 2 天,您可以使用 timedelta()
:
To increment by 2 days if .isweekday() == 6
, you can use timedelta()
:
>>> import datetime
>>> date = datetime.datetime.strptime('2012-02-11' , '%Y-%m-%d')
>>> if date.isoweekday() == 6:
... date += datetime.timedelta(days=2)
...
>>> date
datetime.datetime(2012, 2, 13, 0, 0)
>>> date.strftime('%Y-%m-%d') # if you want a string again
'2012-02-13'
