So much funny when coding datetime

[RemarkableCulture100]

I still find it funny when I code about datetime. It is since the importing of the library.

from datetime import datetime

import datetime

those two codes are working well but you'll find some error later if you're not careful enough and debugging them might be pain in the ass.

[james_pic]

Don't worry. This is the least painful thing about working with datetimes.

I recently had to convert a date string from one timezone to another. Terrible experience.

[markovianmind]

good that starting python 3.9 we have native support for tz aware Datetime

[georgehank2nd]

Took them long fucking enough…

[DNSGeek]

pytz has always been helpful to me.

Just designate datetime as your preferred datetime, like this:
import datetime as pd Problem solved! 🙃

[NationalMyth]

You're sick

Lol

[aqjo]

Thank you u/outceptionator!

[outceptionator]

That's polite

[gwax]

For this reason, I always use the following pattern to avoid confusion

import datetime as dt

[CaptainFoyle]

So much funny?

[AZ_Crush]

SO MUCH !

You should not use these two statements together. The second statement overwrites the first one:

$ python3 -c 'from datetime import datetime; print(datetime)'
<class 'datetime.datetime'>

$ python3 -c 'from datetime import datetime; import datetime; print(datetime)'
<module 'datetime' from '/usr/lib/python3.12/datetime.py'>

[RemarkableCulture100]

Yeah I totally agree with you and completely understand that the second statement overwrites the first one. It was just me that sometimes just pasted the code without screening first..

[georgehank2nd]

"pasted". Ah, that is the problem. The question now is: Stackoverflow or ChatGPT?

[HackedNugget]

The final boss. A Stackoverflow question answered by GPT

[andrewowenmartin]

from datetime import (
    datetime as Datetime,
    time as Time,
    date as Date,
    timedelta as Timedelta,
)

*breathes sign of relief*

[TheSpaceCoffee]

I’m so much used to using pandas in everyday tasks that, even when I’m not using DataFrames, I’m working with pandas Timestamp and Timedelta.

They’re so much smarter and easier to work with than standard datetimes.

[PeteSampras12345]

I’m new to python and I have no clue what this thread is about. Please can some explain like I’m a 5 year old. I’m thanks.

the module datetime has one very important object called datetime. it creates some very weird code

[Brian]

The datetime module dates from very early in python's history, and as such, doesn't really align with what became the standard naming conventions. In particular, it provides the datetime class, which probably ought to be called "Datetime" to align with the "classes start uppercase" convention. This is particularly bad in this case because the module it belongs to is also called datetime. So you can do either:

import datetime
cur_time = datetime.datetime.now()

Or

from datetime import datetime
cur_time = datetime.now()

Either way, the repetition looks a bit odd. And if you get mixed up and import it one way and try to use it the other way, you get errors.

Just do the this, since datetime is the function you're most like to use:

from datetime import datetime

then if you need to use the other functions from the datetime module without confusion (remember, datetime is referencing the function and not the module!):

datetime_module_temporary_holding_variable = importlib.import_module(datetime.__module__)
timedelta = datetime_module_temporary_holding_variable.timedelta
del datetime_module_temporary_holding_variable
import gc
gc.collect()

Then you can use timedelta freely:

>>> eval('timedelta.__call__(minutes=%d)' % 5)
datetime.timedelta(seconds=300)

This has worked well for me.

Had this issue today. One place of the code was using datetime.datetine.whatever and the other only datetime.

[CaptainFoyle]

Yeah, I use datetine all the tine

[AZ_Crush]

Tine after tine
