How to enable Background Processing in python idle outside of Arcmap

[NaimeCelik]

Hello,

I know from arcmap under geoprocessing options you can enable background processing.  Does anyone knoe how to do that with python idle by using python code?

If you are looking to run your Python script outside of an ArcGIS for Desktop session using the 64-bit geoprocessing installation, you simply need to run your script in 64-bit Python.

If you are trying to run your Python script without a visible window, simply change the file extension of your script from .py to .pyw. Double-clicking on a pyw file runs the script without a visible shell/command-prompt window.

Replying to this old thread.

Does checking the box Enable for Background Geeporcessing have ArcMap use pythonw.exe instead of python.exe behind the scenes?
