Here's a neutral, objective, and interesting summary of the text in one paragraph: Twilio has introduced its Programmable Messaging service, which allows developers to send scheduled SMS, MMS, and WhatsApp messages with a single API call. This eliminates the need for custom schedulers, making it easier to automate message sending. To use this feature, developers need to set up a Twilio account, purchase a phone number, create a messaging service, and install the Twilio Python helper library. The library is used to retrieve configuration variables from an environment file and interact with the Twilio API. A sample Python script demonstrates how to send a scheduled WhatsApp message using this library. Once installed, developers can use the `python-decouple` library to handle environment variables and schedule messages at a specific time. By following these steps, developers can integrate messaging into their applications and automate communication with users.
