open 4 panes in the same window using the current session and execute a command there. This is super handy when working in a project with multiple steps required to run and monitor it. Check out here how to use it: https://iterm2.com/python-api/tutorial/running.html

4panes.py

import iterm2

WORKING_DIRECTORY = "/path/to/your/folder"

async def main(connection):
    app = await iterm2.async_get_app(connection)
    window = app.current_terminal_window

    if window is not None:
        # Get the current session (pane)
        session = window.current_tab.current_session

        # Step 1: Split the current pane vertically (left and right panes)
        left_pane = session
        right_pane = await session.async_split_pane(vertical=True)

        # Step 2: Split the left pane horizontally (top-left and bottom-left)
        top_left_pane = left_pane
        bottom_left_pane = await top_left_pane.async_split_pane(vertical=False)

        # Step 3: Split the right pane horizontally (top-right and bottom-right)
        top_right_pane = right_pane
        bottom_right_pane = await top_right_pane.async_split_pane(vertical=False)
        
        # Step 4: Send 'cd' commands to set the working directory for each pane
        await top_left_pane.async_send_text(f"cd {WORKING_DIRECTORY}\n")
        await bottom_left_pane.async_send_text(f"cd {WORKING_DIRECTORY}\n")
        await top_right_pane.async_send_text(f"cd {WORKING_DIRECTORY}\n")
        await bottom_right_pane.async_send_text(f"cd {WORKING_DIRECTORY}\n")

        # Step 5: Send commands to each pane
        await top_left_pane.async_send_text("echo 'Top Left Pane'\n")
        await bottom_left_pane.async_send_text("echo 'Bottom Left Pane'\n")
        await top_right_pane.async_send_text("echo 'Top Right Pane'\n")
        await bottom_right_pane.async_send_text("echo 'Bottom Right Pane'\n")
