Python 将Matrix、Dict保存到文件的方法

>>> import numpy>>> mat = numpy.matrix("1 2 3; 4 5 6; 7 8 9")>>> mat.dump("my_matrix.dat")>>> mat2 = numpy.load("my_matrix.dat")

import numpy my_matrix = numpy.loadtxt(open("c://1.csv","rb"),delimiter=",",skiprows=0) 

numpy.savetxt('new.csv', my_matrix, delimiter = ',')
