Calling Python Script from LabVIEW

[Avni]

Hello Everyone,

I want to call the Python script from LabVIEW.

I tried with using at the command line but i am unable to run that script file..

i have gone through LabPython but i am unable to call the scripts from there also..

If someone has an example of a VI which invokes a python script, it will be very helpful...

Thanks a lot in advance

Regards

Avni

Did you search the forums? A search turned up this example. It's old, but it might still work.

Hi

Thanks a lot for your reply.

I have tried the example which you have shown, but it asks for some python20.dll which i dont have .

I actually need to invoke some scripts at a click of one button and then display the results of that script on one string indicator.

I need to call the scripts at the command prompt only.

If possible if any one has an example of this, it will be of great help.

Thanks a lot in advance.

I think Python needs to be installed in the system or maybe its framework. But I dont know clearly whether aw framework for Python really exists like the one for .Net.

Hi Wiebe,

Thanks a lot for replying.

I have already installed that but that is not helping in my example
I have to invoke the Script file at command prompt.

If you any example in context with this please help me..

Can you descriobe your restriction(s) concerning "invoke the script at the command prompt"?  There may be ways around that.

Sorry 'bout that. It way mentioned a few times. At least it got things going
again.

What is not clear is that you want to run scripts from LabVIEW, but want to
start them from the command line?

I'm not sure how I got LabPython to work. I did it only a few weeks ago. Got
it working, ran the example, and didn't use it anymore. Is your problem
still getting anything to work with Python (including running a script from
the command line)?

Regards,

Wiebe.

Did you try uninstalling Python & reinstalling it?  Barring that, try looking for the missing DLLs online and register them on your system.  I did a quick google of python20.dll and found http://www.processlibrary.com/directory/files/python20/307363.
