二維及其以下陣列利用np.savetxt(filename,ndarray,fmt='',delimiter=' ',newline='/n')輸出很方便，當陣列超過2維，需要將陣列進行切片，變成二維陣列才可以輸出，如：

import numpy as np

if not path is None:
              with file(os.path.join(outpath,ctime+'_synopticscale_front_location.dat'), 'w') as outfile:
                    for slice_2d in path:
                        np.savetxt(outfile, slice_2d,fmt='%0.8f')
                with file(os.path.join(outpath,ctime+'_synopticscale_front_type.dat'),'w')as outfile:
                    for slice_2d in smask:
                        np.savetxt(outfile,slice_2d,fmt='%8d')

                np.savetxt(os.path.join(outpath,ctime+'_synopticscale_flont_influence_area.dat'), np.transpose(frontregion), fmt='%8d', delimiter=' ')
