Answer 1

def make_menubar(frame, textarea):
    menubar = Menu(frame)
    file_menu = Menu(menubar, tearoff=0)
    file_menu.add_command(label="noticeall", command=lambda: noticeall(textarea))
    return menubar


def noticeall(textarea):
    notice_list = ncontroller.select_all()
    textarea.insert(notice_list)

In fact, the best way is to create a class. Pass parameters through self.
