I am new to Heroku and an intermediate learner in Python. I have a python script on my pc that uses Twitter's API and tweets after every 2 minutes. Now the script works fine but I was interested in deploying it on Heroku. So my question is that I have installed the Twitter API(using pip) but how will Heroku use that install? I mean Heroku won't be having that dependency installed so how will it read my code? And do I need to upload the Twitter dependency folder also while deploying my app on Heroku?
