Is there a way to check whether a python script has been run with the interactive option -i?

e.g.

if interactive_mode:
    print 'I am in interactive mode!'
else:
    print 'I am in batch mode!'

Then call with

python hello_world.py
I am in batch mode!

python -i hello_world.py
>> I am in interactive mode!

import sys
if sys.flags.interactive:
    print 'I am in interactive mode!'
else:
    print 'I am in batch mode!'
