Reading and modification of npy files

npy files are used to store the data, graph, dtype, and other information needed to reconstruct the ndarray. Commonly used IO functions are: The load() and save() functions are the two main functions for reading and writing file array data. By default, the array is saved in a file with the extension .npy in uncompressed raw binary format.

import numpy as np
dict={
   
    
    'name':'typxxn','sex':'girl','lan':'python'
