腌制Python错误

Question

我一直在写一个基于文本的文件系统。为了保存数据，我必须将它写入文件，所以我使用了Pickle。在添加第二个泡菜之前，它似乎工作正常。总之它给我这个错误：

当年这里是我的代码：

import datetime 
import time 
import pickle 

file_Name = "testfile" 
file_Name2 = "testfile2" 

accounts = {} 
files = {} 

fileObject2 = open(file_Name2,'r') 
accounts = pickle.load(fileObject2) 

fileObject = open(file_Name,'r') 
files = pickle.load(fileObject) 

def startup(): 
    fileObject2 = open(file_Name2,'wb') 
    pickle.dump(accounts, fileObject2) 
    fileObject2.close() 
    print "\n   -------------------   " 
    print "   FILE SYSTEM MANAGER   "

    if loginornew.lower() == "login": 
     login() 
    elif loginornew.lower() == "account": 
     newaccount() 
    else: 
     startup() 

def newaccout(): 
    print "--------------------------------------------" 
    print "\n Would you like to create a new account?" 
    yesorno = raw_input(" Please enter YES or NO: ") 
    if yesorno.lower() == "no": 
     startup() 
    elif yesorno.lower() == "yes": 
     newusername = raw_input("\n Please enter a username for your account: ") 
     newpassword = raw_input(" Please enter a password for your account: ") 
     newpasswordagain = raw_input(" Please confirm the password for your account: ") 
     if newpassword == newpasswordagain: 
      for username in accounts: 
       if username == newusername: 
        print "\n Username already exists" 
        print " Please try again" 
        newaccount() 
       else: 
        pass 
      accounts[newusername] = newpassword

Answer 1

尝试打开文件与 'RB' 模式。像这样：

... 
fileObject2 = open(file_Name2,'rb') 
... 

告诉我，如果它的工作。
