 col = [] img = "test1" img1 = "test2" col.append(img) col.append(img1) data=np.array(col) np.savetxt('/public/home/student6/test/test.csv',data,fmt='%s') col=[] img2 = "test3" img3 = "test4" col.append(img2) col.append(img3) data=np.array(col) i = 1  np.savetxt('/public/home/student6/test/test'+'%d.csv'%i ,data,fmt='%s')

np.savetxt('/public/home/student6/test/test'+'%d.csv'%i ,data,fmt='%s')
