How to get the external image editor path?

I’d like to know what is the command line to get the external image editor set in the user preferences?

I found this on the documentation : bpy.types.UserPreferencesFilePaths.image_editor but I don’t know how to use it.

Thank you!

bpy.context.user_preferences.filepaths.image_editor

Thank you.

And I realized that I put the topic in the wrong category! Sorry about that!
