Enregistrement et suppression d'un compte

Question

Je déteste venir avec un autre problème le même jour, encore moins deux, mais maintenant j'ai besoin d'un moyen d'enregistrer et de supprimer des comptes. Voici le script entier:

accounts={'Robrajow':'password', 'Hacker':'hack', 'Noob':'lololol1'} 
option1=0 
option2=0 
loop=1 
while loop==1: 
    print "Welcome to Telemology! You can login, register, delete an account, or exit." 
    loginchoice = raw_input("What would you like to do? ") 
    if loginchoice=='login': 
     choice = raw_input("What is your username? ") 
     choice2 = raw_input("What is your password? ") 
     if (choice in accounts): 
      option1=1 
     else: 
      option1=0 
     if (choice2 == accounts[choice]): 
      option2=1 
     else 
      option2=0 
     if option1==1 and option2==1: 
      print "Welcome to Telemology,", choice 
     else: 
      print "The username or password you entered is incorrect. Please try again or register." 
    elif loginchoice=='register': 
     newuser=raw_input("What is your new username? ") 
     if (newuser in accounts): 
      newuser=raw_input("That account name is already taken. Please enter another: ") 
     newpass=raw_input("What is your new password? ") 
     print newuser,", welcome to Telemology!" 
     print newpass, "is your new password!" 
     print "Write it down and hide it!" 
    elif loginchoice=='delete': 
     unsure=raw_input("Do you really want to delete your account? It will never return! ") 
     if unsure=='yes': 
      choice = raw_input("What is your username? ") 
      choice2 = raw_input("What is your password? ") 
      if choice in accounts: 
       option1=1 
      else: 
       option1=0 
      if choice2 in password: 
       option2=1 
      else: 
       option2=0 
      if option1==1 and option2==1: 
       print "Goodbye forever,", choice 
      else: 
       print "The username or password you entered is incorrect." 
     elif unsure=='no': 
      print "I hoped so." 
     else: 
      print "Invalid input." 
    elif loginchoice==exit: 
     print "Goodbye!" 
     loop=0 
    else: 
     print "What? You can only input login, delete, register, or exit." 

Veuillez ignorer les nombreuses erreurs et les lignes de code complexes qui pourraient être remplacées par une seule. J'ai seulement besoin d'un moyen d'enregistrer et de supprimer des comptes (par exemple les entrées du dictionnaire).

En cas de doute que vous décidez de réécrire le script ENTIER pour moi, beaucoup obligé.

Answer 1

Eh bien, vous utilisez un dictionnaire pour stocker des comptes. Pour ajouter un élément à un dictionnaire, vous faites:

accounts["newusername"] = "newpassword" 

Et pour supprimer un élément, il ressemble à:

del accounts["usernametodelete"] 

(Mais je vous suggère de faire passer un peu de temps à travailler sur vos « lignes complexes Par exemple, lorsque vous avez l'ensemble complexe d'instructions if/else définissant option1 et option2, pourquoi ne pas utiliser quelque chose comme:

if choice in accounts and choice2 == accounts[choice]: 

Answer 2

Fixez votre code, il y a beaucoup d'erreurs. Je suppose que c'est ce que vous voulez faire.

>>> if username in accounts: # if the username is in accounts 
    if accounts[username] == password: # check whether the password is same 
     del accounts[username] # if it is, delete the user 
    else: 
     print 'Password invalid' # else tell the user the password is invalid 

Sinon, commentez et je mettrai à jour.

Answer 3

est ici une ré-écriture assez complète:

import hashlib 
import getpass 

class Auth(object): 
    class UserNameTakenError(Exception): 
     pass 

    def __init__(self, userDict): 
     self._users = {name:self.hash(pwd) for name,pwd in userDict.iteritems()} 

    def hash(self, pw): 
     return hashlib.sha256(pw+"&@#salt)(string)846!^").digest() 

    def validate(self, name, pwd): 
     return (name in self._users) and (self._users[name]==self.hash(pwd)) 

    def create(self, name, pwd): 
     if name in self._users: 
      raise Auth.UserNameTakenError() 
     else: 
      self._users[name] = self.hash(pwd) 

    def delete(self, name, pwd): 
     if self.validate(name, pwd): 
      del self._users[name] 

def getYes(msg): 
    return raw_input(msg).lower() in ('y','yes') 

class App(object): 
    def __init__(self): 
     self.auth = Auth({'Robrajow':'password', 'Hacker':'hack', 'Noob':'lololol1'}) 
     self.actions = { 
      'login': self.doLogin, 
      'l':  self.doLogin, 
      'register': self.doRegister, 
      'r':  self.doRegister, 
      'delete': self.doDelete, 
      'd':  self.doDelete, 
      'exit':  self.doExit, 
      'e':  self.doExit, 
      'x':  self.doExit, 
      'q':  self.doExit 
     } 

    def welcome(self): 
     return raw_input("\nWelcome to Telemology! You can Login, Register, Delete an account, or Exit.\nWhat would you like to do? ") 

    def doLogin(self): 
     name = raw_input("What is your username? ") 
     pwd = getpass.getpass("What is your password? ") 
     if self.auth.validate(name, pwd): 
      print "Welcome to Telemology, {0}".format(name) 
     else: 
      print "The username or password you entered is incorrect. Please try again or register." 
     return False 

    def doRegister(self): 
     name = raw_input("What is your new username? ") 
     pwd = getpass.getpass("What is your new password? ") 
     try: 
      self.auth.create(name, pwd) 
      print "{0}, welcome to Telemology!".format(name) 
     except Auth.UserNameTakenError: 
      print "That account name is already taken. Please try again." 
     return False 

    def doDelete(self): 
     name = raw_input("What is your username? ") 
     pwd = getpass.getpass("What is your password? ") 
     if self.auth.validate(name, pwd): 
      if getYes("Do you really want to delete your account? It will never return! "): 
       self.auth.delete(name, pwd) 
       print "Goodbye forever, {0}".format(name) 
      else: 
       print "I hoped so." 
     else: 
      print "The username or password you entered is incorrect." 
     return False 

    def doExit(self): 
     print "Goodbye!" 
     return True 

    def run(self): 
     while True: 
      act = self.welcome().lower() 
      if act in self.actions: 
       if self.actions[act](): 
        break 
      else: 
       print "What? You can only input login, delete, register, or exit." 

def main(): 
    myapp = App() 
    myapp.run() 

if __name__=="__main__": 
    main()
