On calling myfunction.py from terminal it throws raise CommandError("Unknown command: %r" % command_name)
os.environ['DJANGO_SETTINGS_MODULE'] = 'site.settings'
Inside myfunction.py I have tried setting this, but it still doesn't work. Can someone help me out here, probably I am missing out on some important config

Answer 1

Try adding __init__.py to management/ and commands/ directories.

Answer 2

I have solved the issue by adding the django.setup() call, after configuring the environment variable.
Inside myfunction.py, the following changes should be made
from django.core import management
import os
import django
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'site.settings')
django.setup()
def funcA():
management.call_command('customcommand')
funcA()
django.setup() is essential to include because it registers your applications and commands defined in your settings in a standalone script which the manage.py or django-admin takes care usually
