String Case Converter

1.2.0 · active · verified Thu Apr 09

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.

Warnings

gotcha The `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`.
gotcha All `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)`).
gotcha The 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.

Install

pip install stringcase Install stable version

Imports

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

Quickstart

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
