将时间戳转换为ISO日期

Question

I am extracting Data from Mongodb using some date filter. In mongo my date is in ISO format . As i am dynamically adding date from some variable which is in timestamp format(2019-07-15 14:54:53).Getting Empty Result

        curs = col1.aggregate([{'$match':{update_col: {'$gte': last_updt }}},{'$project':json_acceptable_string}])

I am expecting Rows after filtering but acual its giving empty dataset

Answer 1

you can use datetime.strptime to parse the original string to a datetime object, then use datetime.isoformat to get it in ISO format.

try this:

import datetime

original_date = '2019-07-15 14:54:53'

date_obj = datetime.datetime.strptime(original_date, "%Y-%m-%d %H:%M:%S")

iso_date = date_obj.isoformat()

print(iso_date)

Answer 2

try this

from dateutil import parser as date_parser
dt_obj = date_parser.parse('2019-07-15 14:54:53')

where dt_obj is an object of standard datetime.datetime class

Answer 3

You can use fromisoformat . Try

from datetime import datetime 

iso_string = '2019-07-15 14:54:53'
you_date_obj = datetime.fromisoformat(iso_string)
