How do you want the output files to be formatted? Binary data? Textual representation? This function can do both: http://docs.scipy.org/doc/numpy/reference/generated/numpy.ndarray.tofile.htm... And numpy supports a variety of methods for outputting to files (and reading data back in): http://docs.scipy.org/doc/numpy/reference/routines.io.html --PLR On Fri, Jun 8, 2012 at 11:04 AM, bob tnur <bobtnur78@gmail.com> wrote:

Hi every body! I have a &b numpy arrays a=np.loadtxt('çm1.txt',  dtype=np.float, skiprows=2,usecols=[1]) b=np.loadtxt('çm1.txt',  dtype=('x', np.float64),  skiprows=2,usecols=[2])

1. I want to save or write these two arrays and able to see the output as output file, say cm1.out. what about if I have multiple files like cm1.txt,cm2.txt,cm3.txt etc and to produce their corresponding outputs cm1.out,cm2.out,cm3.out etc.

I appreciate your help
