In more typical use, to pickle an object to a flat file, we just open the file in write mode and call the dump function: 典型的使用情况是,pickle对象到无格式文件,我们只需以写模式打开文件,并调用dump函数: % python >>> table = {'a': [1, 2, 3], 'b': ['spam', 'eggs'], 'c'...

The Pickle dump() and dumps() functions are used to serialize an object. The only difference between them is that dump() writes the data to a file, while dumps() represents it as a byte object. Similarly, load() reads pickled objects from a file, whereas loads() deserializes them ...

Import pickle module. Use pickle.dump(object, filename) method to save the object into file <filename>: this will save the object in this file in byte format. Use pickle.load(filename): to load back python object from the file where it was dumped before. ...
