The Python DLL is integrated into Delphi using a free collection of components called Python for Delphi that is P4D. They make it easier to run Python programmes and build new Python types and modules. DLLs can be made for a variety of tasks, including Python extensions.
Python GUIs can be easy to develop and use with a native Windows development tool like Delphi or C++Builder. The Python4Delphi library enables easy interfacing between Python and the rich native VCL framework available in Delphi and C++Builder. Delphi and C++ are powerful programming languages that mesh well with Python.
