用于打开所需软件应用程序的菜单驱动Python程序

在本文中，我们将创建一个菜单驱动的Python程序，该程序将在用户以文本形式提供输入时执行所需的用户工具。

我们可以通过GUI（图形用户界面）和CLI（命令行界面）与 OS 进行交互。我们也可以通过编程语言向操作系统下达指令。在这个程序中，您可以使用Python向操作系统发出指令。该程序提供了我们如何制作基于规则的 ChatBot 的想法。

在这个程序中，我们将使用os.system() 的方法 操作系统模块。此方法在子shell 中执行命令（字符串）。

Syntax: os.system(command)

Return : On Unix, the return value is the exit status of the process and on Windows, the return value is the value returned by the system shell after running command.
 

让我们看看实现：

Python3

# import os library
import os
 
# infinite while loop
while True:
    print("Hello! user choose your tool")
    print("Choose your tool :-\n")
    print("-> mousepad")
    print("-> chrome")
    print("-> vlc")
    print("-> virtualbox")
    print("-> camera")
    print("-> telegram")
    print("-> firefox")
    print("-> codeblocks")
    print("-> screenshot")
    print("-> task-manager")
    print("-> libreoffice impress / presentation")
    print("-> libreoffice writer / text editor / notepad")
    print("-> libreoffice clac / spreadsheets")
    print("-> libreoffice")
    print("-> jupyter notebook\n")
    print("chat with system:-",end=' ')
     
    # take input from user
    p = input()
       
    # check conditions
    if (("do not" in p) or ("dont" in p) or ("don't" in p)):
        print("OK user\n")
         
    elif (("open" in p) or ("start" in p) or ("run" in p) or ("execute" in p) or ("launch" in p) or ("activate" in p)):
         
        if (("mousepad" in p) or ("editor" in p)):
           
            # run mention application
            os.system("mousepad")
             
        elif (("vlc" in p) or ("media player" in p)):
            os.system("vlc")
             
        elif (("virtualbox" in p) or ("virtual machine" in p) or ("virtual tool" in p)):
            os.system("virtualbox")
             
        elif (("camera" in p) or ("cheese" in p)):
            os.system("cheese")
             
        elif ("telegram" in p):
            os.system("telegram-desktop")
             
        elif ("codeblocks" in p):
            os.system("codeblocks")
             
        elif ("taskmanager" in p):
            os.system("xfce4-taskmanager")
             
        elif ("screenshot" in p):
            os.system("xfce4-screenshooter")
             
        elif (("jupyter" in p) or ("notebook" in p)):
            os.system("jupyter notebook")
             
        elif (("libreoffice impress" in p) or ("presentation tool" in p)):
            os.system("libreoffice --impress")
             
        elif (("libreoffice writer" in p) or ("text editor" in p)):
            os.system("libreoffice --writer")
 
        elif ("notepad" in p):
            os.system("notepad")
             
        elif (("libreoffice calc" in p) or ("spreadsheet" in p)):
            os.system("libreoffice --calc")
             
        elif ("libreoffice" in p):
            os.system("libreoffice")
             
        elif ("chrome" in p):
            os.system("google-chrome-stable")
             
        elif (("firefox" in p) or ("mozilla" in p)):
            os.system("firefox")
             
        else :
            print("don't support")
     
    # terminating infinite while loop
    elif (("quit" in p) or ("exit" in p) or ("stop" in p) or ("close" in p) or ("deactivate" in p) or ("terminate" in p)):
        print("Thnank You!")
        break
         
    else :
        print("don't support")

输出：
