[Tips] python 字典 保存

也可以使用numpy

import numpy as np

# Save
dictionary = {'hello':'world'}
np.save('file.npy', dictionary) 

# Load
read_dictionary = np.load('file.npy').item()
print(read_dictionary['hello']) 

　　

或是pickle

def save_obj(obj, fileName):
    with open('{}.pkl'.format(fileName), 'wb') as f:
        pickle.dump(obj, f, pickle.HIGHEST_PROTOCOL)

def load_obj(fileName):
    with open('{}.pkl'.format(fileName), 'rb') as f:
        return pickle.load(f)
