Purity validator for Python code.

Pure validator

Purity validator for Python code.

Overview

Pure validator is a static analysis tool for checking the purity of Python functions and modules. It analyzes Python source code and reports on side effects, global state usage, and other purity-related concerns.

Suppose you have the following code:

def impure_function(): # pragma: pure
    print("This is impure!")

Running the purity checker, will report an error similar to:

example.py:3: Function 'impure_function' is marked as pure but has side effects (print statement)

Features

• Recursively analyzes Python files in directories
• Reports purity violations and messages
• CLI and module entry point (python -mpure_validator)
• Easy integration with CI/CD

Installation

You can install Pure via pip:

$ pip install pure-validator
