python pickle，在重新加载时不存储列表元素

Question

我对编码非常陌生，对于这个特定的代码，我迷路了。 该程序的目的是列出用户输入的名称列表，进行存储，然后在程序重新启动时重新加载。 该程序不会引发错误，但也不会在重新加载时存储任何内容。 我的问题是，为什么不保存列表？ 任何帮助将不胜感激。

这是我尝试的代码：

python 2.7

    <pre>
import os
import pickle

def display_title_bar():
    os.system('cls')
    print("\t***  Greeter - Hello old and new friends!  ***")

#user choice
def get_user_choice():
    print('1- list peopel we know: ')
    print('2- add someone new: ')
    print('3- enter q to exit')
    return raw_input('please enter 1 2 or q :')


def show_name():
    print(' here are the people we know\n')
    for name in names:
        print(name.title())

def get_new_name():
    new_name=raw_input(' please enter name: ')
    if new_name in names:
        print(' we allready know %s' %new_name)# test for existing members.
    else:
        names.append(new_name)
        print('%s has been added to the list\n'%new_name)
def load_names():
    try:
        file_object=open('names.pydata','rb')
        pickle.dump( names, file_object)
        file_object.close()
        return names
    except Exception as e:
        print(e)
        return[]
def quit():
    try:
        file_object =open('names.pydata','wb')
        pickle.dump(names,file_object)
        file_object.close()
        print(' i will rmemeber the names')
    except Exception as e:
        print(e)
        print(' sorry something went wrong')

#Setup a loop where users can choose 
names= load_names()
choice=''
display_title_bar()

while choice !='q':
    # Respond to the user's choice.
    choice=get_user_choice()
    display_title_bar()
    if choice=='1':
        show_name()
    elif choice =='2':
        get_new_name()

    elif choice =='q': 
        quit()
        print('thanks see you again soon')
    else:
        print(' i dont know what is this\n')
