详解Python list和numpy array的存储和读取方法

import numpy as np
numpy_array = np.array([1,2,3])
np.save('log.npy',numpy_array )

import numpy as np
numpy_array = np.load('log.npy')

list_log = []
list_log.append([1,2,3])
list_log.append([4,5,6,7])
file= open('log.txt', 'w') 
  for fp in list_log:
    file.write(str(fp))
    file.write('\n')
file.close()

file=open('log.txt', 'r')
list_read = file.readlines()

label_path = 'C:/Users/leex/Desktop/label.txt'
file = open((label_path),'r')
label = [int(x.strip()) for x in file]
file.close()

import numpy as np
label_path = 'C:/Users/leex/Desktop/label.txt'
label = np.loadtxt(label_path, dtype=np.int64)
