Python Type Checker

A Python Type Checker is a programming language type checker that operates on python code.

• Context:
  • It can perform Static Analysis through python source code parsing.
  • It can enable Type Inference through abstract interpretation.
  • It can validate Type Annotation through python typing syntax.
  • It can detect Type Error through type compatibility checking.
  • It can maintain Type Safety through code flow analysis.
  • ...
  • It can (often) facilitate Development Process through IDE integration.
  • It can (often) provide Error Detection through real-time analysis.
  • It can (often) implement Type Checking Strategy through configuration options.
  • It can (often) support Code Quality through automated verification.
  • ...
  • It can range from being a Simple Type Validator to being an Advanced Type Analyzer, depending on its analysis capability.
  • It can range from being a Standalone Checker to being an Integrated Development Tool, depending on its deployment mode.
  • ...
  • It can integrate with Build System for continuous integration.
  • It can connect to Code Editor for development workflow.
  • It can support Version Control for collaborative development.
  • ...
• Examples:
  • Python Type Checker Implementations, such as:
    • Static Type Checkers, such as:
      • Mypy for standard python type checking.
      • Pyright for microsoft python ecosystem.
      • Pyre for facebook python infrastructure.
      • Pytype for google python codebase.
    • Runtime Type Checkers, such as:
      • Typeguard for runtime type validation.
      • Beartype for performance-oriented checking.
  • ...
• Counter-Examples:
  • Python Linter, which focuses on code style validation.
  • Python Formatter, which handles code formatting.
  • Python Debugger, which performs runtime debugging.
