如何在Python中运行程序。

Question

I am trying to make a script which would run an .exe file from my computer. I think I am using the wrong command. I tried all the other commands like import os, os.startfile , but they aren't working.

Here is my code:

loop=0
while loop==0:
    answer=raw_input("coded by: Narralol\n\n"
    "Pick a task:\n"
    "1) Start Minecraft.exe\n"
    "2) Start Minecraft_Server.jar\n"
    "3) Backup your server\n"
    "4) Copy the backup to your desktop\n"
    "5) Exit\n")
    if answer==1:
        execfile('D:\Games\Minecraft\Minecraft.exe')
    elif answer==2:
        execfile('D:\Games\Minecraft\Minecraft_server.jar')
    elif answer==5:
        loop=1

Answer 1

Use the subprocess module to run external commands:

import subprocess

    subprocess.call('D:\Games\Minecraft\Minecraft.exe')

Answer 2

You can use os.system() like so (note: it is usually better to use subprocess for doing things like this):

answer = 0
while answer < 5:
    answer = int(raw_input("coded by: Narralol\n\n"
    "Pick a task:\n"
    "1) Start Minecraft.exe\n"
    "2) Start Minecraft_Server.jar\n"
    "3) Backup your server\n"
    "4) Copy the backup to your desktop\n"
    "5) Exit\n").strip())
    if answer == 1:
        os.system('D:\Games\Minecraft\Minecraft.exe')
    elif answer == 2:
        os.system('D:\Games\Minecraft\Minecraft_server.jar')
    elif answer == 5:
        break

Changed a few other minor things in the code like checking an int against another int (instead of string against an int), etc.
