Hi Alan,
I rewrote the code as follows:
fname = raw_input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"
fh = open(fname)
count = 0
for line in fh:
if not line.startswith('From'): continue
line2 = line.strip()
line3 = line2.split()
line4 = line3[1]
print line4
count = count + 1
print "There were", count, "lines in the file with From as the first word"
Question: How do I remove the duplicates:
stephen.marqu...@uct.ac.za
stephen.marqu...@uct.ac.za← Mismatch
lo...@media.berkeley.edu
lo...@media.berkeley.edu
zq...@umich.edu
zq...@umich.edu
rjl...@iupui.edu
rjl...@iupui.edu
Regards,
Hal

What makes you think so?
>>No count = count +1
If you get an error(as I suspect) please post the entire error message.
>>OK
I would expect a name error on the last line of the loop since there is
no variable fn defined.
I don't know what you think the seek() is doing, but (assuming
you meant fh) it will reset the file to the first line each time
so you never finish the loop.

Splitting on whitespace will ensure the bit you want is
in the second element
