Running python script in Blender

Question

I installed Blender 2.6 and I'm trying to run a script called drawcar.py (Which uses PyOpenGL)

I looked around the documentation for importing a script and could only access Blender's python console.

How do I run drawcar.py from the Linux terminal with Blender?

For sake of completeness (since this SO page is high on Googles results) -- there is a comprehensive and canonical introduction page in the official documentation. Just as usual, it is somewhat hidden :-D Python API Overview¶ This page describes how Python is integrated and lists all the ways to start python scripts or integrate as extension. — Ichthyo

You can also execute the following code in the python console to execute an external script without opening it up in the text editor:

filename = "/full/path/to/myscript.py"
exec(compile(open(filename).read(), filename, 'exec'))

The above code comes from the following link:

Waaay easier than the accepted answer and doesn't require constant re-load when making changes

But whenever I try to run the script, it reruns the entire script and doesn't delete the last one and mixing both scripts.

Open a Text Editor view in Blender.
Press Alt + O, or go to Text>Open Text Block and open the .py file
Then simply press Run script :D

P.s. Instead of opening a file in step 2, you can also hit the "+ New" button and create a new script instead.

Note : In newer versions the Run Script button label has been replaced with a Play icon :

Thanks, I just figured this out but I don't see a way to see the output of running the script. I checked Blender's console--nothing!

It's not in the console of blender, unfortunately. It's in the terminal window of Blender. For linux/osx, you'll have to run blender from the terminal. And I think for windows there previously was a commandline window opened up alongside of blender. You can still turn this on in the help menu, as stated by this article: blender.org/documentation/blender_python_api_2_59_2/… It could also be in the File menu though.

Hi, I have press the run script button but unfortunately it gives me error "Python script fails. look in the console for now" And in console there is nothing. So how can i guess what error with script? Tried to run this with python console using this filename = "/Users/sandeepsingh/Desktop/objc.py" exec(compile(open(filename).read(), filename, 'exec')) Traceback (most recent call last): File "<blender_console>", line 1, in <module> File "/Users/sandeepsingh/Desktop/objc.py", line 9, in <module> import Blender ImportError: No module named 'Blender' but here shows me error too ?

In windows you can show the Blender system console by going to the menu Window -> Toggle System Console

Is it possible to pass arguments to the python script?

To run a script by another script or from console:

import bpy

script = bpy.data.texts["script_name.py"]
exec(script.as_string())

It is likely that drawcar.py is trying to perform pyOpenGL commands inside Blender, and that won't work without modification. I suspect you are getting some import errors too (if you look at the command console). Blender has it's own internal python wrapper for opengl called bgl, which does include a lot of the opengl standards, but all prefixed by bgl.

If you have a link to drawcar.py I can have a look at it and tell you what's going on.
