This script allows you to send text messages right from your computer using www.24sms.net. It's a very short script and very easy to understand.
Selenium for Python (Google it).
This entire script only has 1 function, "SendText". It will return true if your message was sent successfully. Otherwise, it will return false.
This code was originally included in Trello-Notification-Alert, but I decided to make it a project of its own.
