How to use SAP GUI Scripting inside Python Programming Language

[Stefan-Schnell]

The programming language Python offers many possibilities. Also it supports with py32win ActiveX automation, and therefore SAP GUI Scripting. The following example shows, how easy it is to take the recorded VBScript code and to use it inside Python.

In the comment lines you see the recorded VBScript code as a direct comparison. Here an example which opens TAC SE16, enters table TADIR and execute the TAC:

#-Begin-----------------------------------------------------------------



#-Includes--------------------------------------------------------------

import sys, win32com.client



#-Sub Main--------------------------------------------------------------

def Main():



  try:



    SapGuiAuto = win32com.client.GetObject("SAPGUI")

    if not type(SapGuiAuto) == win32com.client.CDispatch:

      return



    application = SapGuiAuto.GetScriptingEngine

    if not type(application) == win32com.client.CDispatch:

      SapGuiAuto = None

      return



    connection = application.Children(0)

    if not type(connection) == win32com.client.CDispatch:

      application = None

      SapGuiAuto = None

      return



    session = connection.Children(1)

    if not type(session) == win32com.client.CDispatch:

      connection = None

      application = None

      SapGuiAuto = None

      return



   #session.findById("wnd[0]").resizeWorkingPane 173, 36, 0

    session.findById("wnd[0]").resizeWorkingPane(173, 36, 0)

   #session.findById("wnd[0]/tbar[0]/okcd").text = "/nse16"

    session.findById("wnd[0]/tbar[0]/okcd").text = "/nse16"

   #session.findById("wnd[0]").sendVKey 0

    session.findById("wnd[0]").sendVKey(0)

   #session.findById("wnd[0]/usr/ctxtDATABROWSE-TABLENAME").text = "TADIR"

    session.findById("wnd[0]/usr/ctxtDATABROWSE-TABLENAME").text = "TADIR"

   #session.findById("wnd[0]").sendVKey 0

    session.findById("wnd[0]").sendVKey(0)

   #session.findById("wnd[0]/tbar[1]/btn[8]").press

    session.findById("wnd[0]/tbar[1]/btn[8]").press()



  except:

    print(sys.exc_info()[0])



  finally:

    session = None

    connection = None

    application = None

    SapGuiAuto = None



#-Main------------------------------------------------------------------

if __name__ == "__main__":

  Main()



#-End-------------------------------------------------------------------

 

And after all we see that it is very easy to use SAP GUI Scripting inside Python. The recorded VBScript code can use almost always unchanged, sometimes it is necessary to set some brackets.

As IDE I use VS Code with Python extension, here a look at it:
