AttributeError: ‘str‘ object has no attribute ‘strftime‘

from datetime import datetime, date

now_date = '2021-6-24 15:23:29.000227'
nowdate = now_date.strftime(now_date,"%m/%d/%Y")

    Want to get only... From the moment represented by a string “ year / month / Japan ”, But running the above code will report an error 'str' object has no attribute 'strftime'.

    The improvement method is as follows ：

now_date = datetime.strptime(now_date, '%Y-%m-%d %H:%M:%S.%f')
now_date = now_date.strftime("%m/%d/%Y")

    We need to use it first. .strptime() take string Format variables into datetime Time format under , And then reuse it .strftime() obtain “ year / month / Japan ”.

PS： If you want to get the day of the week today ,datetime.strptime().weekday() + 1
