详解Python list和numpy array的存储和读取方法

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

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