source venv/bin/activate

prerequisitions:

open twitter and slack dev user and get credential for api and use the credential in .env file for intearacting with their services.

need to have .env file :

ACCESS_TOKEN = 'something...' will be use like:
os.environ['something...']

in current project in twitter_communicator.py file will use:
os.environ['ACCESS_TOKEN']
os.environ['ACCESS_TOKEN_SECRET']
os.environ['CONSUMER_KEY']
so prepare corrosponding vars in .env

and in slack_communicator.py :
