Question1: The output result is an address or line?
Its your assignment,. you tell me.
But from your previous mails I'm assuming you want addresses?
Question2: Why are there 54 lines as compared to 27 line in the desired
output?
Because the set removes duplicates? So presumably there were 27
duplicates? (Which is a suspicious coincidence!)
fname = raw_input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"
fh = open(fname)
count = 0
addresses = set()
for line in fh:
if line.startswith('From'):
line2 = line.strip()
line3 = line2.split()
line4 = line3[1]
addresses.add(line4)
count = count + 1
print addresses
print "There were", count, "lines in the file with From as the first word"
That looks right in that it does what I think you want it to do.
The output result:
set(['stephen.marqu...@uct.ac.za', 'lo...@media.berkeley.edu', '
zq...@umich.edu', 'rjl...@iupui.edu', 'c...@iupui.edu', 'gsil...@umich.edu',
'wagne...@iupui.edu', 'antra...@caret.cam.ac.uk','
gopal.ramasammyc...@gmail.com', 'david.horw...@uct.ac.za', '
r...@media.berkeley.edu']) ← Mismatch
That is the set of unique addresses, correct?
There were 54 lines in the file with From as the first word
And that seems to be the number of lines in the original file
starting with From. Can you check manually if that is correct?
The desired output result:
stephen.marqu...@uct.ac.za
lo...@media.berkeley.edu
zq...@umich.edu
rjl...@iupui.edu
zq...@umich.edu
rjl...@iupui.edu
...
Now I'm confused again. This has duplicates but you said you
did not want duplicates? Which is it?
...
c...@iupui.edu
c...@iupui.edu
There were 27 lines in the file with From as the first word
And this is reporting the number of lines in the output
rather than the file (I think). Which do you want?
Its easy enough to change the code to govre the output
you demonstrate, but that's not what you originally asked
for. So just make up your mind exactly what it is you want
out and we can make it work for you.
