在CLI中创建可单击项

Question

因此，我正在创建一个小型python程序，它将使用subprocess.call()函数启动其他程序。我想知道是否有任何方法可以在CLI中共同创建可单击的框，以帮助用户知道他/她有什么选项，并使其更易于选择。你知道吗

目前我只使用input()函数和if/elif/else函数来确定要启动什么。我想把它转换成CLI上的一个可点击的界面，这样除了点击之外就不需要任何输入了。你知道吗

这是我目前正在使用的。还没有找到任何关于这样一个选择的材料，也许我找得不够仔细。你知道吗

import getpass
import subprocess
import os
OSPath = "/SYS64 3.7/"
full_path = os.getcwd()
CurrentPath = ""
dir_path = os.path.dirname(os.path.realpath(__file__))
answer = input("INPUT BOOT PARAMETER ")
if answer == "jdos":
    subprocess.call(["python3",dir_path + OSPath + "bootthingy.py"])
    subprocess.call(["python3",dir_path + OSPath + "jdosos.py"])
elif answer == "jdos.fboot":
    subprocess.call(["python3",full_path + OSPath + "jdosos.py"])
elif answer == "jdos.admin":
    user = getpass.getpass("username: ")
    password = getpass.getpass("password: ")
    bootcheck = 0
    with open('userpass.txt', 'r') as file:
        for line in file:
            line = line.strip('\n')
            login = line.split(',')
            if login[0] == user and login[1] == password:
                subprocess.call(["python3",full_path + OSPath + "jdososadmin.py"])
                bootcheck = 1
        if bootcheck == 0:
            print("Incorrect user or password.")
elif "jdos.exp" in answer:
    subprocess.call(["python3",full_path + OSPath + "jdosexperimentail.py"])
elif answer == "cancel":
    print("")
else:
    print("invalid")

与用户在input()中键入jdos不同的是，您将有4个包含4个不同选项的可单击框，它们看起来像这样：[jdos] [jdos.fboot] [jdos.admin] [jdos.exp]，如果单击，每个框都运行subprocess.call()

我尝试过使用npyscreen包，但未能成功运行

这就是我使用提供的npyscreen代码时的样子。你知道吗

NPYScreen code works!

这就是当我选择一个框并点击OK时发生的情况

Python program does not launch properly...

如您所见，程序确实在运行，它只是覆盖了最上面的文本，并且我无法在input('C:/SYS64 3.7> ')函数中输入任何内容，我认为这可能会导致npyscreen应用程序无法关闭。我对npyscreen还是个新手，我不知道它到底是怎么工作的。你知道吗

Answer 1

Npyscreen允许您制作控制台应用程序，您可以要求用户提供一些信息。你知道吗

你可以继续使用这个模板，我只是用基本的方法。我建议你阅读这个图书馆的文献。你知道吗

        self.parentApp.setNextForm(None)

    def on_cancel(self):
