[Numpy-discussion] numpy arrays

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
