Spring is all\u00a0about cleaning, the saying goes, so why don’t apply the same principle also the the accounts I follow on Twitter?\u00a0Why? Because I would like to maintain their number under 400 and because I\u00a0would like to grow my very limited Python skills.<\/p>\n
With the help of\u00a0TweetPony<\/a>\u00a0(among the many), the task was pretty straightforward. Final result is a simple script<\/a> that checks for the people I follow, verifies their last tweet date and alert me if it is older than four months.<\/p>\n I don’t want to pollute my system-wide Python installation with libraries and dependencies related to a single project, so I created a virtual environment<\/a>. Still not a master on that, so forgive my errors:<\/p>\n From now ongoing, all the pip commands will be execute inside the (build_dir)<\/em> virtualdev, and not at system-wide level. Time to install the TweetPony library:<\/p>\n Once installed, I tried some examples from the GitHub repo<\/a>, to check if it worked. And yes, it did (even without api key and permission, see later), but a boring console message appeared every time the script made a call to Twitter API, caused probably by the old Python 2.7.6 version or libs I was using:<\/p>\n In order to solve it<\/a>, I installed some dev libraries required to compile some other Python libraries (again, inside the virtualenv only)<\/p>\n and added these lines of code at the beginning of the main function of the script, before any Twitter API call:<\/p>\n They made the trick! But, as I said, probably you may not need all of these.<\/p>\n The script itself it’s pretty simple. I took the basic code to create the TweetPony API object from the repo’s example folder<\/a> and I was able to get user’s friends_id (the account the user follows). Then, cycling thru each one, I checked the status of that friend, watching for last tweet date. Some cornercases management (like private tweets or no tweets at all) and voila’, I had all I needed.<\/p>\n Regarding authentication, all Twitter’s libraries require a consumer key and consumer secret to work, in addition to an OAuth access_token and access_token_secret. What made me preferred TweetPony to other libs, like tweepy<\/a> or python-twitter<\/a>, was that TweetPony doesn’t required anything. Test consumer key and secret are gently embedded into the lib source, while OAuth tokens are created on the fly for you and persisted over a file, .auth_data.json<\/em>. To use new credentials, simply delete the file and add somewhere, at the beginning of your code, these two lines, with key and secret obtained from Twitter Dev Console:<\/p>\n Final consideration about Twitter API usage: there is a limit<\/a> of 180 calls every 15 minutes, so I added a sleep after every check. Slow, but it worked with my 500+ followers :) Spring is all\u00a0about cleaning, the saying goes, so why don’t apply the same principle also the the accounts I follow on Twitter?\u00a0Why?
