Intersystems Iris - embedded python


I'm starting testing embedded python and external libraries.

When I try to use the win32api-library I get the following error :

<THROW> *%Exception.PythonException  230 ^^0^ <class 'ModuleNotFoundError'>: No module named 'win32api' -

This is my code :

ClassMethod CreateDocument(path As %String) [ Language = python ]
import win32api


The librarie is visible in C:\InterSystems\IRIS\mgr\python\win32.

Am I doing something wrong ?

Hello @Kurt Hofman ,

I experienced a similar problem the last week while testing a library.

To solve it, I created the PYTHONPATH system environment variable with C:\InterSystems\IRISHealth\lib\python\Lib\site-packages\win32;C:\InterSystems\IRISHealth\lib\python\Lib\site-packages\win32\lib.
IRIS need to be restarted to consider any change in an environment variable.

Check If pythoncom39.dll and pywintypes39.dll exist in the directory C:\InterSystems\IRISHealth\lib\python\Lib\site-packages\win32. If they don't exist, copy them. I don't remember the initial directory of these dll files (maybe C:\InterSystems\IRISHealth\mgr\python\pywin32_system32).

I'm a beginner in Python, so maybe a more simple and clean solution exists...

Hope this help.
