Sometimes, we want to convert a UTC datetime to a local datetime using only standard library with Python.
In this article, we’ll look at how to convert a UTC datetime to a local datetime using only standard library with Python.
How to convert a UTC datetime to a local datetime using only standard library with Python?
To convert a UTC datetime to a local datetime using only standard library with Python, we can use the pytz module.
For instance, we write
import pytz
local_tz = pytz.timezone('Europe/London')
def utc_to_local(utc_dt):
local_dt = utc_dt.replace(tzinfo=pytz.utc).astimezone(local_tz)
return local_tz.normalize(local_dt)
to create the utc_to_local function that takes the utc_dt datetime.
In it, we call utc_dt.replace with the tzinfo argument set to pytz.utc to parse the datetime as UTC.
Then we call astimezone with local_tz to convert the UTC datetime to the local_tz time zone.
And then we call local_tz.normalize with the local_dt to return the local datetime.
Conclusion
To convert a UTC datetime to a local datetime using only standard library with Python, we can use the pytz module.
