You just need to indent your last print statement so it is inside the loop and put the heading print statement before the loop. print """ TimestepPE""" for line in cols: ts = line[0] pe = line[1] print "%s %s " % (ts,pe) You might also like to use stroing formatting to force column widths to be constant: print "%20s%20s" % (ts,pe) should illustrate...adjust the size to suit.

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

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()

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()
Put the print statement in the for loop.
for line in cols:
...
print "%s %s " % (ts,pe)

You should print the header before the loop, and the contents inside the
loop. So:
print """
TimestepPE"""
for line in cols:
ts = line[0]
#print line[0]
pe = line[1]
#print line[1]
# The next line is indented so it is included in the loop:
print "%s %s " % (ts,pe)
You probably will want to set the field width in the print format so the columns all line up,
something like this (just guessing on the widths):
print "%10s %10" % (ts,pe)

pretty-printing a table:
