Get path to Blender executable How to get Blender executable's file path in a Python script?

__file__ gives me my addon's path, but I cannot be sure Blender is in the same folder tree, I guess.
You can get it using bpy.app.binary_path

Blender's API docs say:


  bpy.app.binary_path:
  The location of blenders executable, useful for utilities that spawn new instances`
