Python – 使用pickle库对变量进行序列化存储

import pickle

data = {'a': 1, 'bb': 2, 'cc': 3}

with open('tmp.pk', 'wb') as f:
    pickle.dump(data, f)

import pickle

data = {'a': 1, 'bb': 2, 'cc': 3}

with open('tmp.pk', 'wb') as f:

pickle.dump(data, f)

import pickle

with open('tmp.pk', 'rb') as f:
    data = pickle.load(f, encoding='bytes')

    print(data)
    '''结果为 {'a': 1, 'bb': 2, 'cc': 3} '''

import pickle

with open('tmp.pk', 'rb') as f:

data = pickle.load(f, encoding='bytes')

print(data)

'''结果为 {'a': 1, 'bb': 2, 'cc': 3} '''
