from os import sep, getcwd, chdir
from subprocess import Popen

from simple_browser import run_browser

if __name__ == "__main__":
    task_list = []
    path = getcwd() + sep + r"notebook"
    chdir(path)
    task = Popen(r"jupyter lab", shell=True)
    task_list.append(task)

    browser = run_browser()
    if browser:
        task.terminate()
        task.kill()
        sys.exit()

最终效果，没有多个title标题栏清爽多了 jupyter client
