Python 中变量的保存和读取

1. 保存为matlab可读的.mat文件

from scipy.io import savemat
savemat(\'ab.mat\', {\'a\': a, \'b\': b}) 

 2. 使用numpy保存为.npy或者.npz文件

import numpy as np

np.save(\'a\', a = a)
data = np.load(\'a.npy\')
a = data[\'a\']

np.savez(\'a\', a=a, b=b)
data = np.load(\'a.npz\')
a = data[\'a\']
b = data[\'b\']

 3. 使用numpy保存字典

import numpy as np

a = [1, 2, 3]
b = [4, 5, 6]

ab = {\'a\': a, \'b\': b}
np.save(\'data.npy\', ab)

data = np.load(\'data.npy\', allow_pickle=True)
a = data.item()[\'a\'] 
b = data.item()[\'b\']
