import numpy as np

data = np.array([[1,2], [3,4]])

np.savetxt('out.txt', data, fmt="%d") #保存为整数

np.savetxt('out1.txt', data, fmt="%.2f", delimiter=',') #保存为2位小数的浮点数，用逗号分隔

with open('out.txt') as f:

    for line in f:

        print(line, end='')

1、python保存numpy数据：

numpy.savetxt("result.txt", numpy_data)

2、保存list数据：

file=open('data.txt','w') 

file.write(str(list_data)); 

file.close()
