Creating .lyr with Python script

[NicolasRoux2]

Hello everyone, 
  
I'm short to give you my ultimate goal of importing into a MXD file a symbology from a Python
script.  

In the wait, the script must scan a series of "image" objects, list them, integrate them into a .lyr file and complete the process by integrating it into the famous .MXD file.   
I managed to list the pictures. To create a lyr file from an existing toc. 
But I do not see how to turn them into .Lyr and inject everything into the MXD.   

I am available for any exchange on this subject.

Hi Nicolas,

Would you be able to share your current script?

Also, to confirm, you would like to add a layer file to an MXD via python or you would like to apply the symbology from a layer file to a layer in an MXD?  

Best of luck,

Marisa

Hi Marisa,

I'd like to add new symbology items (PNG files for example) on an empty layer on ArcMap. I don't have at first a .style element or anything else.

On docs, arcmap could read or update list of items via Python by creating an array. And I don't understand how to convert this array on a .style or .lyr file. And add this on an MXD file.

I can create a list :

I don't understand to create it in a Python array...

And at the end, is this example from ArcGIS Doc a good thinking way ?

Thanks for your reading.

Nicolas
