## What it is
Python4Delphi (P4D) is a set of free Delphi and Lazarus (FPC) components that wrap the Python DLL, enabling execution of Python scripts, creation of Python modules and types, and bi-directional Delphi-Python interaction. It offers low-level Python API access, high-level object interop via custom variants and RTTI wrapping, and the ability to build Python extension modules as DLLs.

## Use cases
- embed python scripting in a delphi application
- call python code from pascal
- create python extension modules in delphi
- expose delphi objects to python scripts
- run python scripts from a lazarus app
- use python as a scripting language for desktop apps

## When to choose
- you are building Delphi or Lazarus/FPC applications and want to embed or interoperate with Python
- you need bi-directional access between native Pascal code and Python objects
- you want to ship Python extension modules written in Delphi

## When to avoid
- your project does not use Delphi, Free Pascal, or Lazarus
- you only need to run Python scripts standalone without native Pascal integration
- you need CPython C-API bindings for C/C++ rather than Pascal
