In the last sessions we have seen that P4D (Python 4 Delphi) is powerful enough to offer components, Python packages or libraries in Delphi or Lazarus (FPC). This time we go the other way of usage and integration; how does the Python or web world in the shell benefit from the VCL components as GUI controls. We create a Python extension module from Delphi classes, packages or functions. Building Delphi’s VCL library as a specific Python module in a console or editor and launching a complete Windows GUI from a script can be the start of a long journey.
