CommonPy: A Collection of Useful Utility Functions for Python Projects

Are you tired of reinventing the wheel with every Python project? Do you find yourself repeatedly writing the same utility functions and classes? Look no further than CommonPy, an invaluable collection of commonly used utilities that will streamline your Python development process.

Features and Functionality

CommonPy offers a wide range of utility functions and classes, carefully designed to simplify common programming tasks. Some of the key features include:

Data Structures: The data_structures module provides data classes such as CaseFoldDict and CaseFoldSet, which allow for case-insensitive key comparison in dictionaries and sets.
Data Utilities: The data_utils module offers a variety of functions for common data operations, such as expanding ranges, flattening lists or dictionaries, parsing datetimes, pluralizing words, and more.
File Utilities: The file_utils module provides simple yet powerful functions for working with files and directories, including operations like copying, deleting, renaming, checking file readability, and more.
Interruptible Wait and Interruption Handling: The interrupt module introduces functions like wait and interrupt that allow for interruptible waiting and graceful program termination.
Module Utilities: The module_utils module is particularly useful for working with module-related paths, making it easier to find internal data files and resources.
Network Utilities: The network_utils module offers a set of functions for common network operations, such as downloading files, extracting hostnames from URLs, checking network availability, and more.
String Utilities: The string_utils module provides handy functions like antiformat for safely quoting curly braces in format strings and print_boxed for printing messages with ASCII art borders.
System Utilities: The system_utils module includes a function to generate a string describing the system running the Python program.

With these and many other utility functions and classes, CommonPy simplifies and accelerates your Python programming, allowing you to focus on the core logic of your projects.

Target Audience and Use Cases

CommonPy has been designed with Python developers in mind. It caters to a wide range of use cases, including:

Data Manipulation: Use CommonPy’s data utilities to efficiently process and transform data, whether you’re working with ranges, nested structures, or date parsing.
File and Directory Operations: Simplify common file and directory tasks, such as copying, deleting, renaming, checking file readability, and more, with CommonPy’s file utilities.
Network Operations: CommonPy’s network utilities provide essential functions for downloading files, handling network availability, and checking URLs.
Module and System Operations: Leverage CommonPy’s module and system utilities to work with internal module resources and generate system-level information.

Whether you’re a beginner or an experienced Python developer, CommonPy offers an accessible and powerful toolkit to enhance your development workflow and increase your coding efficiency.

Technical Specifications and Innovations

What sets CommonPy apart from other utility libraries is its comprehensive collection of diverse and well-documented functions and classes. These utilities have been carefully crafted by the team at the Caltech Library, drawing on their expertise and experience in Python development.

CommonPy is compatible with Python 3.6 and higher, ensuring compatibility with the latest versions of Python. It can be easily installed using pip from the Python Package Index (PyPI) or directly from the CommonPy GitHub repository.

CommonPy leverages several open-source packages, including boltons, dateparser, h2, httpx, and more, to provide a robust and reliable set of utilities. It also ensures a high level of code quality and maintainability by utilizing tools like pytest for testing and twine for packaging and publishing to PyPI.

Competitive Analysis and Key Differentiators

While there are several utility libraries available for Python, CommonPy stands out for its comprehensive coverage of various domains and its focus on usability and simplicity. Some key differentiators include:

Diverse Functionality: CommonPy covers a wide range of areas, from data manipulation to file handling, network operations, and more. It aims to be a one-stop solution for common utility needs, reducing the need for developers to search for and integrate multiple libraries.
Ease of Use: CommonPy prioritizes user-friendliness and simplicity. Each function and class is well-documented, making it easy for developers to understand and use the utilities effectively.
Community Support: CommonPy is actively maintained by the team at the Caltech Library, ensuring timely updates, bug fixes, and community support. Contributions from the open-source community are also welcome, enhancing the library’s functionality and ensuring its continued growth.
Integration with Existing Workflow: CommonPy seamlessly integrates with your existing Python workflow. Its compatibility with popular Python packages and adherence to best practices means that you can incorporate it into your projects without disruption.

Example Code

Here’s a brief code excerpt showcasing the usage of the readable function from the file_utils module:

#python
from commonpy.file_utils import readable

if readable('/path/to/some/file'):
    # Perform actions on the readable file
    ...
