How to sleep on rate limit in Python?
Python-Twitter tries to abstract away the details of Twitter’s rate limiting by allowing you to globally respect those limits or ignore them. If you wish to have the application sleep when it hits a rate limit, you should instantiate the API with sleep_on_rate_limit=True like so:
