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
