I follow steps mentioned in the KB article : Getting started with Python to install Python and do configuration to use ZOS-API with Python. But I still cannot make it work.
I did: 

  •  Install 64 bit Python 3.7.4 under C:\ directory  (according to recommendation)
  •  Configure Windows PATH environment 
  •  Install and upgrade pip 
  •  Install corresponding pywin32 module 
  •  Follow instructions under Troubleshooting python section to re-registering the wrappers 
    • Navigate to {Python}\Lib\site-packages\win32com\gen_py\*.* and delete all the filed in that (gen_py) directory.
    • Open a Windows "cmd” window (Windows Key + R -> type “cmd” -> press “Enter”)
    • Change directory to your {PythonEnv}\Lib\site-packages\wind32com\client\ folder (i.e., “cd C:\Python37\Lib\site-packages\win32com\client”)
    • Type “python makepy.py” and press enter.  When the Select Library window pops up, use the Ctrl key to select both the ZOSAPI and the ZOSAPI_Interfaces and click OK.

    Problem of wrappers being broken usually can be fixed by above troubleshooting steps. 
    But Python installation will have influence on imported module path. For my situation: 
    Check generating to path when apply the troubleshooting steps in the Windows 'cmd' window. 
    Note the module is imported into a different path, not under C:\Python37
    Though system path of Python is under C:\ directory in my case, user path is not the right folder.    




    My solution here is reinstall Python follow steps:
    1. Check 'Add Python 3.7 to PATH', click Customize installation: 
     
     
            2. Check all and Next:
            3. Choose folder C:\ by clicking Browse, please don't type in location path by hand :

    4. install pywin32 module and back to CMD window to check if importing success.
