call-datetime-today (DTZ002)#
Derived from the flake8-datetimez linter.
What it does#
Checks for usage of datetime.datetime.today()
.
Why is this bad?#
datetime
objects are "naive" by default, in that they do not include
timezone information. "Naive" objects are easy to understand, but ignore
some aspects of reality, which can lead to subtle bugs. Timezone-aware
datetime
objects are preferred, as they represent a specific moment in
time, unlike "naive" objects.
datetime.datetime.today()
creates a "naive" object; instead, use
datetime.datetime.now(tz=)
to create a timezone-aware object.
Example#
Use instead:
Or, for Python 3.11 and later:
