Flask Webcast #3: Circular Dependencies

In this live webcast I explain how to prevent circular dependency errors in Python. Most of this presentation is a live coding session in which I refactor a single-file Flask application into a fully fleshed out structure with multiple packages and modules, demonstrating how I completely avoid circular dependencies.

    How are you testing this with tox flake8? Can you explain it a little when and how it is used for testing dependancies, and whether I can use it on my Windows as well? Thanks

    @Haris: I don't have a copy of the configuration that I used in this video, but I don't use it for anything specifically related to circular dependencies, just to make sure that after I do some refactoring work there are no obvious mistakes. And yes, this works on Windows as well.

    Hola Miguel, Congratulations, your blog is really a reference about Flask. Thank you for sharing.
