Scripting: Blender Window

There is a hierarchical setup for a blender window with the Window Manager on the bottom.

• Window Manager
• Window
  • Workspace
  • Screen (Screen Operators)
    • Area
    • Regions

import bpy

# Get Windows
wm = bpy.context.window_manager
for win in wm.windows:
    print(win)

# Get Areas
for area in bpy.context.screen.areas:
    print(f"{area.type:<13} at {area.x:>4}, {area.y:>4} and {area.width:>4}, {area.height:>4} size")

Splitting an area

Works from Blender 3.2 on:

import bpy

for area in bpy.context.screen.areas:
    if area.type == 'IMAGE_EDITOR': # 'VIEW_3D', 'CONSOLE', 'INFO' etc. 
        with context.temp_override(area=area):
            bpy.ops.screen.area_split(direction='VERTICAL', factor=0.3)
        break

(from stackexchange)

Joining two areas

Sadly this isn't working up to Blender 3.3 according to Harleya from the blender forums.
