python - 关闭程序后如何保存数据？

Question

我目前正在使用字典制作电话簿目录。我不知道关闭程序后有什么方法可以保存信息。我需要保存变量信息，以便稍后添加更多内容并打印它。

    Information={"Police":911}
    def NewEntry():
        Name=raw_input("What is the targets name?")
        Number=raw_input("What is the target's number?")
        Number=int(Number)
        Information[Name]=Number

    NewEntry()
    print Information

编辑:我现在正在使用 Pickle 模块，这是我当前的代码，但它不起作用:

     import pickle
     Information={"Police":911}
     pickle.dump(Information,open("save.p","wb"))
      def NewEntry():
         Name=raw_input("What is the targets name?")
         Number=raw_input("What is the target's number?")
         Number=int(Number)
         Information[Name]=Number
    Information=pickle.load(open("save.p","rb"))
    NewEntry()
    pickle.dump(Information,open("save.p","wb"))
    print Information

您可以使用Pickle模块:

 import pickle

 # Save a dictionary into a pickle file.    
 favorite_color = { "lion": "yellow", "kitty": "red" }
 pickle.dump( favorite_color, open( "save.p", "wb" ) )

或者:

 # Load the dictionary back from the pickle file.
 favorite_color = pickle.load( open( "save.p", "rb" ) )
