Is there a way to call a Python code in Excel-VBA?

Question

I have an Excel file (Main.xlsm) containing macros. I have a Python file (python.py) to generate a subsidiary Excel file (sub.xlsx) which I would further call in the macros

Answer 1

There are multiple ways tu run a python script with VBA depending on whether you need to wait for the end of the execution and know if it went without error.

With Shell, asynchronous with console:

Public Sub RunPython(file As String, ParamArray args())
  Shell "python.exe """ & file & """ " & Join(args, " ")
End Sub

With Shell, synchronous without console:

Public Function RunPython(file As String, ParamArray args())
  Shell "pythonw.exe """ & file & """ " & Join(args, " ")
End Function

With WScript.Shell, synchronous without console and with exit code:

Public Function RunPython(file As String, ParamArray args()) As Long
  Dim obj As Object
  Set obj = CreateObject("WScript.Shell")
  RunPython = obj.Run("pythonw.exe """ & file & """ " & Join(args, " "), 0, True)
End Function
