You have a Textobject. The strftimefunction requires a datetime object. The code below takes an intermediate step of converting your Textto a datetimeusing strptime
你有一个Text对象。该strftime函数需要一个日期时间对象。下面的代码需要将您的转换Text为datetimeusing的中间步骤strptime
import datetime
testeddate = '4/25/2015'
dt_obj = datetime.datetime.strptime(testeddate,'%m/%d/%Y')
At this point, the dt_objis a datetime object. This means we can easily convert it to a string with any format. In your particular case:
此时，dt_obj是一个日期时间对象。这意味着我们可以轻松地将其转换为任何格式的字符串。在您的特定情况下：
dt_str = datetime.datetime.strftime(dt_obj,'%Y-%m-%d %H:%M:%S')
The dt_strnow is:
在dt_str现在是：
'2015-04-25 00:00:00'

A less elegant solution would involve manipulating the string directly.
一个不太优雅的解决方案是直接操作字符串。
testeddate = '4/25/2015'
month, day, year = testeddate.split('/')
testeddate = '-'.join([year, month, day]) + ' 00:00:00'
