Timezone in HH:MM Format

Hello,

How can I convert a date, usually datetime.now(), into a format where
the timezone is in hours:minutes format. I was able to get that format
in shell:

$ date +%Y-%m-%dT%H:%M:%S%:z
2024-06-18T19:24:09-04:00

The closest I got in python is

from datetime import datetime
from zoneinfo import ZoneInfo

s = datetime.strftime(datetime.now(ZoneInfo("America/New_York")),
"%Y-%m-%dT%H:%M:%S%z")
print(s)

This prints the same as the shell command above except the last column:
2024-06-18T19:28:56-0400

Any help will be appreciated.

Regards
Ivan
