I have a problem with converting isoformat to datetime.
I have this:
[{'timex-value': '2019-W32T15:00', 'start': 18, 'end': 31, 'text': '3pm next week', 'type': 'TIME', 'value': '2019-W32T15:00'}]
How can I convert '2019-W32T15:00' to datetime format in python?
To get a date time object you would want something like this. However you you will not get a the correct answer because you do not have a day of the week.
import date time as dt
dt.datetime.strptime('2019-W32T15:00','%Y-W%WT%H:%M')
If you want a successful conversion to a date time then specify the first day of that week by adding a 1 to the timex-value string.
import date time as dt
dt.datetime.strptime('2019-W32T15:00'+'-1','%Y-W%WT%H:%M-%w')
Result: datetime.datetime(2019, 8, 12, 15, 0)

I need to add +3 hours to a date in iso 8601 format in python, for example "2022-09-21T22:31:59Z" due to time difference. In this time information that is returned to me from the API, I only need Y/M/D information, but due to the +3 hour difference, the day information needs to go one step further in the date information, as will be experienced in the date I conveyed in the example. How can I overcome this problem? I think the format of the date format is ISO 8601 but can you correct me if I am wrong?
ex. api response;
"createdDateTime": "2022-09-21T22:31:59Z"
what i need;
"createdDateTime": "2022-09-21T22:31:59Z" to "2022-09-22T01:31:59Z"
Try this code it will definitely work:
from datetime import datetime,timedelta
parsed_date=datetime.strptime("2022-09-21T22:31:59Z", "%Y-%m-%dT%H:%M:%SZ")
Updated_date = parsed_date+ timedelta(hours=3)
print(Updated_date)
If you have a proper JSON string you can parse it with json, extract the string value, parse that with datetime.fromisoformat into a datetime value and then get the date from it :
import json
from datetime import datetime
data=json.loads('{"createdDateTime": "2022-09-21T22:31:59+00:00"}')
isostr=data['createdDateTime'].replace('Z','+00:00')
fulldate=datetime.fromisoformat(isostr)
fulldate.date()
-----
datetime.date(2022, 9, 21)
The replacement is necessary because fromisoformat doesn't understand Z
Adding 3 hours to fulldate will return 1 AM in the next day:
fulldate + timedelta(hours=3)
------
datetime.datetime(2022, 9, 22, 1, 31, 59, tzinfo=datetime.timezone.utc)
fulldate is in UTC. It can be converted to another timezone offset using astimezone
fulldate.astimezone(tz=timezone(timedelta(hours=3)))
---
datetime.datetime(2022, 9, 22, 1, 31, 59, tzinfo=datetime.timezone(datetime.timedelta(seconds=10800)))
Or in a more readable form:
fulldate.astimezone(tz=timezone(timedelta(hours=3))).isoformat()
---------------------------
'2022-09-22T01:31:59+03:00'
This is 1AM in the next day but with a +3:00 offset. This is still the same time as 22PM at UTC.
It's also possible to just replace the UTC offset with another one, without changing the time values, using replace:
fulldate.replace(tzinfo=timezone(timedelta(hours=3))).isoformat()
----------------------------
'2022-09-21T22:31:59+03:00'
That's the original time with a different offset. That's no longer the same time as 2022-09-21T22:31:59Z
I'm taking input that looks like "8-15 14:45" and trying to turn it into a datetime object (and then turn it back into a string). My issue is that it sets the year to 1900, but I need the year set to this year. How do I accomplish this?
So far I have datetime.datetime.strptime('8-15 14:45', '%m-%d %H:%M') which gives me datetime.datetime(1900, 8, 15, 14, 45) but I need datetime.datetime(2021, 8, 15, 14, 45). I'd like to not hardcode 2021 if I can help it.
Apologies if this is answered somewhere, my google-fu has failed me.
Use datetime.replace with datetime.today().year:
this_year = dt.datetime.today().year
dt.datetime.strptime('8-15 14:45', '%m-%d %H:%M').replace(year=this_year)
You can use the method now() of the datetime class and only ask for the property year of the returned datetime object:
from datetime import datetime
t = datetime.now().year
print(t)
>>> 2021
You can do this by replacing the year on the parsed date like this:
from datetime import datetime as dt
date = dt.strptime('8-15 14:45', '%m-%d %H:%M')
date = date.replace(year=dt.now().year)
I'm trying to convert strings in a list to datetime format on Python. I am unable to use pd.DateTime at the moment. The imported datetime package doesn't seem to work. I'm new to this.
Please help.
Cheers.

You should consider using official datetime formats
Example:
from datetime import datetime
#datetime(year, month, day)
date = datetime(2018, 11, 28)
# datetime(year, month, day, hour, minute, second, microsecond)
date = datetime(2017, 11, 28, 23, 55, 59, 342380)
you can use strptime
from datetime import datetime, strptime
my_datetime_list = [strptime(string_date, '%y-%m-%d') for string_date in list_of_string_dates]
I am using dateparser in scrapy to convert the date format.
Original date format: Apr 16, 2019
After using dateparser: 2019-04-16 00:00:00
This is what I wanted to achieve. However, I would still like to remove the time from the date format, so in the end, I only have 2019-04-16. Unfortunately, I am not able to realize this.
This is my line of code:
import dateparser
...
def parse_site(self, response):
def get_with_xpath(query):
return response.xpath(query).get(default='').strip()
yield {
'date': dateparser.parse(get_with_xpath('//meta[#name="date"]/#content'))
}
As I said, it works. But the time stamp I would like to remove. Any ideas?
Dateparser.parse returns datetime representing parsed date if successful. You can use strftime() function to remove the timestamp as shown below
dateparser.parse('Apr 16, 2019').strftime("%Y-%m-%d")
Methods of this library return all values in datetime format. But afterwards you are free to do with them anything you want. Check this example:
>>> import dateparser
>>> dateparser.parse("Apr 16, 2019")
datetime.datetime(2019, 4, 16, 0, 0)
>>> dateparser.parse("Apr 16, 2019").date()
datetime.date(2019, 4, 16)
I have a case in my Django :
Variable 't' get data from database. I print 't' variable and the result is 'datetime.time(16, 59, 59)'. It means at 16:59:59.
I want to combine today's date with these time. Does anyone know?
The result that I want is (for example) : 'datetime.datetime(2014, 10, 22, 16, 59, 59)' which is combine from today's date is '2014-10-22' and specified time like '16:59:59'.
Thank you.
Use datetime.combine:
from datetime import datetime, date, time
datetime.combine(date(2014, 10, 22), time(16, 59, 59)).
its what that datetime.combine is for and date.today() returns todays date :
>>> from datetime import datetime ,date , time
>>> datetime.combine(date.today(), time(16, 59, 59))
datetime.datetime(2014, 10, 22, 16, 59, 59)
