Question

I have a small problem here, I\'m trying to sum up entries from multiple files (50), and each of them contain 3 columns. for example, using the first 3 files: file1.txt, fi

Answer 1

In [1]: import numpy as np

In [2]: from StringIO import StringIO

In [3]: txt ="""2 3 4
   ...: 1 5 6
   ...: 5 4 7"""

In [4]: f = StringIO(txt)

In [5]: arr = np.loadtxt(f,dtype = int)

In [6]: np.sum(arr,axis = 0)
Out[6]: array([ 8, 12, 17])
