I am using PythonAnywhere for my Python programming class for two years as suggested by the textbook that I used. I have a good experience with its user interfaces. The student is also enjoying it. It is literally anywhere because you can use it on your phone, tablet, or desktop. I also love their customer support. They are very friendly to accommodate my needs as a teacher/professor.

Being able to run Python code directly in the cloud is an excellent option. In addition, being able to test the same code with different versions of Python greatly facilitates programming time.

The deployment process is very quick and hassle free, better than anything I've come across. You get one server and two consoles for free per account. You can git clone your project or upload it manually to the file system and even perform text edits afterwards. Deploying Django projects are as easy as selecting your virtual environment, project directory, static and media files directory and configuring the wsgi file. You can also choose between MySQL/PostgreSQL if needed. The whole process can be done in less than 30 minutes if you're experienced enough. And since you get a free tier, this is almost the perfect place to test out your project before putting it in production. And the pricing to scale up your project is very generous
