PyRequire

A bunch of decorators for checking specific requirements of Python functions at runtime.

Features

• Simple decorators to enforce required Python version or package versions at runtime
• Flexible version specification using standard comparison operators (e.g., >=, <, ==)
• Lightweight, with no runtime dependencies
• Helps ensure reproducibility and compatibility in code execution

Installation

The recommended way to install pyrequire is through the Python Package Index:

pip install pyrequire --user

Otherwise, clone and extract the package, then run from the package location:

pip install . --user

To test the integrity of the installed package, check out this repository and run:

pytest

Examples

from pyrequire import require_package, require_python

@require_python(">=3.9")
@require_package("foo>=1.2.3")
def bar():
    return
