我需要用 pickle 来保存字典

Question

我想在字典中保存键和值并在明天或下周使用它 我读过书“A byte of Python”

import os
import pickle

addressbook = {}
home = os.environ['HOME']
path = home + '/.local/share/addressbook'
addressbookfile = path + '/' + 'addressbook.data'
if not os.path.exists(path):
    os.mkdir(path)
    
while True:
    print("What to do?: ")
    print("1 - full list")
    print("2 - add a contact")
    print("3 - remove contact")

    answer = int(input("Number of answer: "))

    if answer == 1:
        f = open(addressbookfile, 'rb')
        storedlist = pickle.load(f)
        print(storedlist)
    elif answer == 2:
        namecontact = str(input("Enter the name of cantact: "))
        name = str(input("Enter the name: "))
        lastname = str(input("Enter the lastname: "))
        number = int(input("Enter the number: "))
        addressbook[namecontact] = [name, lastname, number]
        f = open(addressbookfile, 'wb')
        pickle.dump(addressbookfile, f)
        f.close()

Answer 1

Python pickle 序列化和反序列化对象，可用于将变量保存到文件中供以后使用。

正如您所做的那样，变量保存在

pickle.dump(addressbook , f)

您可以使用加载数据

addressbook = pickle.load(f)

其中 f 是您的文件句柄
