Need to 'import datetime' and 'from datetime import datetime' but this causes an-CodePudding

I am trying to do both import datetime and from datetime import datetime, however I am getting a redefinition unused error.

Is there anyway just to import either of them? I tried to delete one, but based on my code it seems I need both?

Here is my code:

import datetime
from datetime import datetime
from typing import Union


def to_date(date: Union[str, int]) -> datetime.date:
    """Convert `date` from `20201130`/`"20201130"`/`"2020-11-30"`to a datetime.date object."""
    date = str(date)
    try:
        yyyy, mm, dd = date.split("-")
    except ValueError:
        yyyy, mm, dd = date[:4], date[4:6], date[6:]
    return datetime.date(int(yyyy), int(mm), int(dd))


def epoch_nanoseconds_to_human_date(date):
    """"Convert an EPOCH nanosecond date to a human readable date"""

    # Converting EPOCH nanoseconds to datetime in seconds
    datetime_in_seconds = datetime.fromtimestamp(date // 1000000000)

    # Convert datetime to human readable date
    return datetime_in_seconds.strftime('%Y%m%d')

When I run the above, I get redefinition of unused 'datetime' from line 1

If I remove the first datetime import, then the return statement of the first function int(mm) and int(dd) is flagged and causes an error.

if I remove the second datetime import, then in the second function fromtimestamp causes an error.

Any idea how I can just import one- from my understanding I need both.

CodePudding user response：

You can do something like import datetime as dt or remove the from datetime import datetime line and use it as datetime.datetime instead.

Cheers.

You can only use

import datetime

Where you need the datetime class inside datetime module you can use

datetime.datetime
