[Tutor] Printing columns of data

[Kooser, Ara S]

Hello all,

   I am writing a program to take a data file, divide it up into columns
and print the information back with headers. The data files looks like
this

      0.0 -3093.44908 -3084.59762   387.64329    26.38518  0.3902434E+00
-0.6024320E-04  0.4529416E-05
      1.0 -3094.09209 -3084.52987   391.42288   105.55994  0.3889897E+00
-0.2290866E-03  0.4187074E-03
      2.0 -3094.59358 -3084.88826   373.64911   173.44885  0.3862430E+00
-0.4953443E-03  0.2383621E-02
	etc...
	10.0 ...

So I wrote the program included below and it only prints the last line
of the file.

Timestep    PE
10.0      -3091.80609 

I have one question. Do I need to put ts and pe into a list before I
print then to screen or I am just missing something. Thanks.

import string

inp = open("fort.44","r")
all_file = inp.readlines()
inp.close()

outp = open("out.txt","w")

cols = map(string.split,all_file)
##print cols

Data = {}
for line in cols:
    ts = line[0]
#    print line[0]
    pe = line[1]
#    print line[1]

print """

Timestep    PE"""
print "%s      %s     " % (ts,pe)


outp.close()
