translating nodes in PAFEC

Given a data file, with nodes defined:

a = file('ct1b.DAT')
b = a.readlines()
c = b[36:500]  # only node entries
d = [i.strip('\n').split(' ') for i in c]
e = []
for i in d:
    tmp = [float(j) for j in i]
    e.append(tmp)
f = array(e)
f[:, 2] = f[:, 2] + 0.001  # apply offset
for i in f:
    print str(i).strip('[]')  # copy and paste.
