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

Acknowledgements
This project started when I saw that the package python-stringcase was flagged-out-of-date in the Arch AUR Repository.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.
