Free Udemy courses everyday!

UdemyPy 🤖

UdemyPy is a bot that hourly searches for Udemy free courses and shares them on:

• Telegram
• Twitter

🔌 How does it work?

For publishing new courses, UdemyPy follows these steps:

1. UdemyPy looks for courses at Discudemy, UdemyFreebies and TutorialBar.
2. The courses found are compared to those previously found. A new_courses list is generated and stored into the database.
3. new_courses are shared on social media.

This process is run hourly, everyday.

🔌 How are repeated courses detected?

Since UdemyPy scrapes different websites constantly, it must remember which courses have already been shared.
Every hour UdemyPy gets a list of free Udemy courses: courses_found. This list contains courses which haven't been shared yet and courses that have. For each course in courses_found, UdemyPy tries to add it to the database. If it fails, the course is already in the database (therefore the course has already been shared). If it success, the course is stored in a courses_added list.
Finally, the courses_added list is shared on social media.
