使用python脚本运行xfce4-terminal下拉菜单，而不会立即关闭它

Question

我创建了以下脚本

#!/bin/bash

import subprocess
import sys
from datetime import datetime
from curtsies import Input

locale = datetime.now()
locale = locale.strftime("%m %Y")
locale = locale.split(' ')
MONTH = locale[0]
YEAR = locale[1]

subprocess.Popen(['clear'], shell=False)
subprocess.Popen(['cal', MONTH, YEAR], shell=False)

while True:
    with Input(keynames='curses') as input_generator:
        for key in input_generator:
            if (key is '') or (key is 'q'):
                sys.exit()
            elif (key is 'KEY_UP') or (key is 'w'):
                YEAR = str(int(YEAR)+1)
            elif (key is 'KEY_DOWN') or (key is 's'):
                YEAR = str(int(YEAR)-1)
            elif (key is 'KEY_RIGHT') or (key is 'd'):
                if (MONTH == '12'):
                    MONTH = '1'
                    YEAR = str(int(YEAR)+1)
                else:
                    MONTH = str(int(MONTH)+1)
            elif (key is 'KEY_LEFT') or (key is 'a'):
                if (MONTH == '1'):
                    MONTH = '12'
                    YEAR = str(int(YEAR)-1)
                else:
                    MONTH = str(int(MONTH)-1)
            subprocess.Popen(['clear'], shell=False)
            subprocess.Popen(['cal', MONTH, YEAR], shell=False)

如果我打开一个终端窗口并输入python3 /path/ to /file.py，它就能完美地工作。然而，我很贪婪，我想用一个命令来打开它，在这个终端运行的情况下创建一个下拉终端。我尝试了以下命令：

xfce4-terminal --geometry 135x40-0+0 --command "python3 ~/.config/polybar/polybar-scripts/calendar-polybar.py" --hide-menubar --hide-toolbar --hide-scrollbar --hide-borders --drop-down --title Calendar

但它会立即打开和关闭。由于我的脚本中有一个无限循环，我以为它会一直打开，直到我强制关闭它或简单地按下退出键，但终端在欺骗我。我做错了什么？

好吧，我不知道为什么终端在你的情况下不阻塞并等待程序返回，但以下替代方案如预期的那样工作：

xfce4-terminal --geometry 135x40-0+0 --command "sh -c 'python3 ~/.config/polybar/polybar-scripts/calendar-polybar.py'" --hide-menubar --hide-toolbar --hide-scrollbar --hide-borders --drop-down --title Calendar

xfce4-terminal --geometry 135x40-0+0 --hide-menubar --hide-toolbar --hide-scrollbar --hide-borders --drop-down --title Calendar --execute python3 ~/.config/polybar/polybar-scripts/calendar-polybar.py
