Python. From the very beginning

[michaelk]

Is there something I need to install before running a Python script?

I'm unable to get any Python script to run, even "Hello, World"

I've tried translating some existing one line scripts with no success.

For example, this is a simple one-liner I often use from VS:

SetPref(44,FALSE);

What would that look like in Python?

Thanks!

Interesting....

Can someone check this?

1. In a VW script editor window, select Python as the language and type in

vs.AlrtDialog('Hello')

2. Run the script. Works Great.

3. Edit the script. Add a space in the wrong place:

vs.Alrt Dialog('Hello')

4. Run the script. Get the error message, click "View Error Output..."

The Script Errors dialog box says:

File "", line 1

vs.Alrt Dialog('Hello')

^

SyntaxError: invalid syntax

5. Click on Edit Script...

Remove the space. Click OK.

6. Run the script again.

I get the same error. If I edit the script by right clicking in the RB and choosing Edit... the edit "sticks". If I choose edit Edit Script... from the Script Errors dialog the edit doesn't "stick".

The lack of indentation in this forum is going to be a problem for python scripts....

[michaelk]

Now that I (maybe) understand why I was unable to edit a script to make it run...

vs.SetPref(44, False) works as a python script.

At first I was trying to use Message instead of AlrtDialog

vs.Message('Hello')

returns the error:

Traceback (most recent call last):

File"", line 1, in

AttributeError: 'module' object has no attribute 'Message'

Any ideas?

thanks

SetPref(44,FALSE);

try:

vs.SetPref(1,True)

Hi Jonathan

I got SetPref to work fine in Python. My problem was what I suspect is an edit bug in the VS editor.

This whole thread started because I couldn't make vs.Message() work (still can't) and I ran in to the editor bug.

Any ideas about vs.Message?

i cant make vs.Message() work

Neither can I. Bug submitted.

[michaelk]

I submitted also.

Is anyone else seeing the Edit bug?

[MullinRJ]

Yes. I did, but only once. I made some other changes and saved them, then pasted the vs.AlrtDialog() statement back and it worked. After that I couldn't make it fail, even in a new file. Perhaps restarting VW might help it fail again.

It's an intermittent bug, at best. Did you file?

Just tried it again after a restart. Same thing. Changes made after a syntax error using the Edit Script... button in the Script Errors dialog box don't work.

Bug filed.

Hello Michael

Python works for me(win xp sp3 and 8), i download PythonSample_Menu2.

I test it(got errors), when i looked at code:

1. i put ui* dir to site-packages dir, because natively there is not such name of class in VW pyAPI

2. modify main(.py) fuction - this, adding execute() to end

* - dir from sample - PythonSample_Menu2\ui\

vs.Message('Hello')

returns the error:

Traceback (most recent call last):

File"", line 1, in

AttributeError: 'module' object has no attribute 'Message'

Any ideas?

Does it has reference to palette gui?, like c4d status

[Vlado]

Hey guys, it seems the vs.Message was not added to python. This omission be fixed in SP2.

[Vlado]

Hi Ilay, you should not copy anything to 'site-packages' from the sample. Unzip the sample in your user's plug-ins folder and that should be all.

when a vsm, vsm, or vst runs, VW adds that folder to the python search path. So, when the scripts does 'import import ui.dlgHandler' the first thing python would do is to look for a folder 'ui' next to the vsm.

Hello Vladislav

Thanks a'lot

Anyway can we use additional math/graphical libs as Numpy an etc.?

honestly i don't like such scheme*:

Currently pyAPI has dependence from vwvs

* - hmm, that why i made several test project, and they did not work properly.

Yes, you should be able to. Those you should install in the side packages.

Neither can I. Bug submitted.

Has anyone else had the same problem with

STRING = vs.GetFldName(h, index)
