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 casefy
Casefy is also available as an Arch Linux AUR package.
Note: for more details, you can check the API Reference.
import casefy # camelCase string = casefy.camelcase("foo_bar") print(string) # fooBar string = casefy.camelcase("FooBar") print(string) # fooBar string = casefy.camelcase("FOO BAR") print(string) # fooBar # snake_case string = casefy.snakecase("fooBar") print(string) # foo_bar string = casefy.snakecase("fooBARbaz", keep_together=["bar"]) print(string) # foo_bar_baz string = casefy.snakecase("FOO BAR") print(string) # foo_bar # CONST_CASE string = casefy.constcase("fooBar") print(string) # FOO_BAR # kebab-case string = casefy.kebabcase("fooBar") print(string) # foo-bar # separator case string = casefy.separatorcase("fooBar", separator="/") print(string) # foo/bar string = casefy.separatorcase("fooBARbaz", separator="%", keep_together=["bar"]) print(string) # foo%bar%baz # Sentence case string = casefy.sentencecase("fooBar") print(string) # Foo bar

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python-stringcase was flagged-out-of-date in the Arch AUR Repository.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 with
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.
