Using Python modules

Where do I need to copy Python modules to so I can use them in my Python code in Lianja?

Please advice on how I can make use of Python to access/determine the serial number of a USB drive.
I am aware that I can make use of microsoft WMI (Windows Management Instrumentation) but I stumble on how to perform the imports of the modules required. The resources I am looking at is http://timgolden.me.uk/python/wmi/index.html This shows need to use pywin32 that is where I can't figure out how to add to Lianja.

Hi Cox,

C:\lianja\scriptinglanguages\python\Lib

This is the path used by python which is setup in the registry when you install Lianja.

HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.7\ PythonPath
C:\lianja\scriptinglanguages\python\Lib;C:\lianja\ scriptinglanguages\python\DLLs;C:\lianja\scripting languages\python\Lib\lib-tk

I am trying to run a for in range loop python as follows via a command

for num in range(5):
Lianja.writeLog(num)

p.s, there is a tab before th Lianja.writeLog.


not getting any output in the log.
running RC10

Hello Cox,

Try it from the python tab in the console workspace.

Hi,

Lianja.writeLog() takes a string.

I have managed to gather system details using python & vbscript and during this exercise, found that I did need to make use of modules that are not default in the lianja distribution (hence moved to next solution). Could a breakdown on how this is achieved be put forward please since copying a given directory into the python/lib didn't work for me.
Most of the documentations talked about installing the module to the current python on system, but as a distributed python, couldn't figure this out.

Of interest was pywin32.

http://sourceforge.net/projects/pywin32/

Need: To get unique serial number (Manufacture number) associated with a USB key.

Hi Cox,

I was able to use the msi installer for pywin32, but I had to change a couple of the Registry entries created by the Lianja for Python to do so. (I'll get these checked out for final release.)

I'm on Win64, so I have:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python

on Win32 the root will be (applies to the entries that follow):

HKEY_LOCAL_MACHINE\SOFTWARE\Python

The Lianja installer puts InstallPath here:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\Pyt honCore\InstallPath

but I think it should be one level lower, i.e.

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\Pyt honCore\2.7\InstallPath

and the (Default) string value it contains should be the python folder under Lianja. For a default installation, this is:

C:\Lianja\scriptinglanguages\python\

Also, this:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\Pyt honCore\2.7\InstallPath\InstallGroup

should have the (Default) string value of:

Python 2.7

Yvonne

Note: the Forum editor is adding a space in 'PythonCore' - there should be no space.

Please see images, I have made the registry changes as shown,

Attachment 483
and tried to install WMI-1.4.9.win32 (https://pypi.python.org/pypi/WMI/#downloads). as shown in the install pane, the entry for installation directory is as follows (C:\Lianja\scriptinglanguages\python\Lib\site-packages\)
Attachment 484

Have tried at the console to run

import wmi, but getting error

Code:

Hi Cox,

It looks like you don't yet have pywin32 installed and wmi sits on top of it. Once you have pywin32 installed, copy the dlls from C:\Lianja\scriptinglanguages\python\Lib\site-packages\pywin32_system32 into your Windows System folder and you should be up and running.

Thanks, that sort it. just needed to add the dll's to systems directory. Just to confirm now that a published application when moved to a new machine will have these covered...

Hi Cox,

Calling the following as administrator, should also do it (default Lianja installation path used here):

Code:

---

cd c:\lianja\bin
c:\lianja\scriptinglanguages\python\python c:\lianja\scriptinglanguages\python\scripts\pywin32_postinstall.py -quiet -install
