stringcase

library1.2.0pypypi✓ verified 25d ago

Stringcase is a lightweight Python library providing functions to convert strings between various common casing conventions, such as camelCase, snake_case, PascalCase, kebab-case, and more. It is a stable, single-purpose utility with no external dependencies, currently at version 1.2.0, and typically sees infrequent updates unless new casing styles or critical bug fixes are required.

camelcase

snakecase

✓ from stringcase import snakecase

stringcase

✓ import stringcase

Imports the module, functions are then accessed via `stringcase.camelcase()`

Demonstrates basic usage of `stringcase` to convert between camelCase, snake_case, kebab-case, and PascalCase using the module-level functions.

import stringcase # Convert to camelCase camel = stringcase.camelcase('hello_world') print(f"camelcase: {camel}") # Expected: helloWorld # Convert to snake_case snake = stringcase.snakecase('HelloWorld') print(f"snakecase: {snake}") # Expected: hello_world # Convert to kebab-case kebab = stringcase.kebabcase('helloWorld') print(f"kebabcase: {kebab}") # Expected: hello-world # Convert to PascalCase pascal = stringcase.pascalcase('hello-world') print(f"pascalcase: {pascal}") # Expected: HelloWorld

Known issues

gotchaThe `uppercamelcase` function is an explicit alias for `pascalcase`. If you expect a distinction between the two, be aware that they perform the same conversion.

fix

Use `pascalcase` directly or be aware that `uppercamelcase` behaves identically to `pascalcase`.

affects: All versions

gotchaAll `stringcase` functions expect a string as input. Providing non-string types (e.g., `None`, integers, lists) will typically result in a `TypeError` or `AttributeError`.

fix

Ensure inputs are always strings. If inputs might be non-string, pre-process them (e.g., `str(value)` or check `isinstance(value, str)`).

affects: All versions

gotchaThe library primarily focuses on common English-based casing conventions and may not handle complex Unicode characters or non-Latin scripts as expected for all casing transformations. Test thoroughly with internationalized strings.

fix

Validate output with non-ASCII or complex Unicode strings if your application requires global character support. Consider character normalization if specific Unicode behaviors are needed.

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'stringcase'

The `stringcase` library is not installed in the current Python environment.

fix

pip install stringcase

AttributeError: module 'stringcase' has no attribute 'snake_case'

The user attempted to call a function using snake_case for the function name itself (e.g., `snake_case`) instead of the library's convention where function names are lowercase (e.g., `snakecase`).

fix

import stringcase
stringcase.snakecase('hello world')

AttributeError: 'int' object has no attribute 'replace'

A `stringcase` function was called with a non-string input (e.g., an integer or None), leading to internal string manipulation methods being called on an object that does not support them.

fix

Ensure the input to any `stringcase` function is a string: `stringcase.camelcase(str(123))` or `stringcase.snakecase('my input string')`.
