[Python知识库]每日学习--python pickle模块

任意复杂的对象《==》对象的文本或二进制表示（双向转换）

1. 序列化
   pickle.dump()，二进制的形式（’wb’）序列化到文件fw

  with open(vocab_path, 'wb') as fw:
        # 序列化到文件fw
        pickle.dump(word2id, fw)

	w_file = open("../Data/weibo/word_embedding.pickle", "wb")
    pickle.dump([W, W2, word_idx_map, vocab, max_l], w_file)
    w_file.close()

pickle.dumps()，不需要写入文件，直接返回一个序列化的bytes对象

pickle.dumps(obj, protocol=None,*,fix_imports=True)

2. 返序列化
   pickle.load()

    with open(vocab_path, 'rb') as fr:
        #反序列化方法加载输出
        word2id = pickle.load(fr)
