Casefy (/keɪsfaɪ/) is a lightweight Python package to convert the casing of strings. It has no third-party dependencies and supports Unicode.
The latest release can be installed using pip:
pip install -U casefyCasefy is also available as an Arch Linux AUR package.
Note: for more details, you can check the API Reference.

This project started when I saw that the package python-stringcase was flagged-out-of-date in the Arch AUR Repository. The project stringcase seems not to be actively maintained anymore, so I decided to address its issues and pull requests and solve them in this new package. I kept the API as similar as possible, in order to facilitate any possible migration. I thank Taka Okunishi (author of stringcase) and its contributors for their work.

case-conversionoffers a very similar functionality as this project. I probably wouldn't have written this package if I had known of it before. However, the code of Casefy is more lightweight and just enough for most cases. If you need more functionality, e.g., detecting the case of a string, go withcase-conversion. -
Inflection presents some overlap with this project as well, allowing the transformation of strings from CamelCase to underscored_string, but also singularizing and pluralizing English words.
