pythonrequires

pythonrequires is a Python package that helps manage package dependencies for Python projects. It allows developers to specify the required Python version and other package dependencies in a structured way. This helps ensure that projects can be reliably installed and run in different environments.

The primary mechanism used by pythonrequires is a `requirements.txt` file, a common convention in the Python ecosystem. However, pythonrequires enhances this by providing additional capabilities for dependency specification. It can be used to define a project's base requirements, as well as optional dependencies that can be installed as needed. This is particularly useful for libraries that have different feature sets or compatibility requirements.

By centralizing dependency information, pythonrequires simplifies the process of setting up a project for development, testing, and deployment. It helps avoid "it works on my machine" scenarios by clearly defining the environment needed for a project to function correctly. When a project is installed, tools that integrate with pythonrequires can read the dependency definitions and install the correct versions of all required packages. This promotes consistency and reproducibility across different development and production environments. The package aims to be a straightforward and effective tool for managing Python project dependencies.
