And the winner is...
As you may know, requires.io is all about being notified of outdated dependencies on PyPI packages.
Therefore we are a privileged observer of the Python community, and it was high time we release some data!
We'll share some more in the upcoming weeks, but let's start with the most popular packages expressed as the percentage of repositories (followed by requires.io) that depends on them:
The result will not come as a surprise: Django is number one with almost 33% of the projects depending on it. We were also quite happy to notice that quality related tools (like coverage, mock, flake8, etc.) rank quite high on the list, evidence that the Python community cares a lot about code quality!
To package maintainers: not on the list? Send us an email and we'll share figures with you.
