This fork has modification which allow to use Python4Delphi together with CrossVcl ( to build VCL application for macOS and Linux using Delphi. Advanced

P4D Logo

Python for Delphi (P4D) is a set of free components that wrap up the Python DLL into Delphi and Lazarus (FPC). They let you easily execute Python scripts, create new Python modules and new Python types. You can create Python extensions as DLLs and much more. P4D provides different levels of functionality:

  • Low-level access to the python API
  • High-level bi-directional interaction with Python
  • Access to Python objects using Delphi custom variants (VarPyth.pas)
  • Wrapping of Delphi objects for use in python scripts using RTTI (WrapDelphi.pas)
  • Creating python extension modules with Delphi classes and functions

P4D makes it very easy to use python as a scripting language for Delphi applications. It also comes with an extensive range of demos and tutorials.

How to use Python4Delphi

The best way to learn about how to use Python for Delphi is to try the extensive range of demos available. Also studying the unit tests for VarPyth and WrapDelphi can help understand what is possible with these two units.
