在服务器上运行python，执行来自计算机的命令

Question

我用python制作了一个登录系统。它完美的工作，但我想在服务器或网络上运行脚本。例如：Steam。 Steam需要用户名和密码才能登录。所以我想为我的脚本做同样的事情。我怎样才能做到这一点？

我的代码：

import os 
import string 
import time 

version = "1.0 Alfa" 

def login(): 
    print ("----------------------------------------") 
    print ("    Login     ") 
    print ("----------------------------------------") 
    k_name = input("Enter username: ") 
    if os.path.exists(k_name + ".txt") == False: 
     print ("Username not found.") 
     create() 
    else: 
     k_pass = input("Enter password: ") 
     with open(k_name + ".txt", "r") as f: 
      if k_pass == f.read(): 
       print("Welcome %s!"%k_name) 
       f.close() 
       input() 
      else: 
       print("Password is wrong!") 
       create() 



def create(): 
    print("You using login system %s" % version) 
    print("----------------------------------------") 
    print("|     Lobby    |") 
    print("----------------------------------------") 
    starting = input("To create user type R, to login type L").upper() 
    if starting == "R": 
     name = input("Enter username: ") 
     password = input("Enter password: ") 
     password2 = input("Enter password again: ") 
     if password == password2: 
      newfile = open(name + ".txt", "w") 
      newfile.write(password) 
      newfile.close() 
      print("User created. Redirecting you to login.") 
      time.sleep(2) 
      login() 
     elif password != password2: 
      print("Passwords doesn't match.") 
      input() 
      create() 
    elif starting == "L": 
     login() 
    else: 
     print("\nWrong button\n") 
     create()

这里是一个可以运行该脚本：蟒蛇test.py用户通过 如果没有找到文件，它会保存数据并进行登录

#!/usr/bin/env python 
import sys, getopt

    print ("----------------------------------------") 
    print ("    Login     ") 
    print ("----------------------------------------") 
    if username: 
     k_name = username 
    else: 
     k_name = input("Enter username: ") 
    if os.path.exists(k_name + ".txt") == False: 
     print ("Username not found.") 
     create(username, password, "R") 
    else: 
     if password: 
      k_pass = password 
     else:

     with open(k_name + ".txt", "r") as f:
