python 读取、写入 pkl文件

使用pickle这个包，注意pkl是一个二进制文件，因此写入和读取的时候都需要使用wb或rb

案例

import pickle


def write_pkl(write_data, pkl_path):  # 写入pkl
    pickle.dump(write_data, open(pkl_path, 'wb'))


def read_pkl(pkl_file):  # 读取pkl
    my_data = pickle.load(open(pkl_file, 'rb'))
    return my_data


if __name__ == '__main__':
    path = 'dict_data.pkl'
    data = ['1234', 123, 4, {'1': 3}]
    
    # 写入pkl文件
    write_pkl(data, path)
    # 读取pkl文件
    read_pkl_content = read_pkl(path)
    
    print(read_pkl_content)
