Hi Emile,
I hope this answers your question?
Question: How do I remove each duplicate line output?
Here is the raw data code:
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"
The problem is in the output results:
Python 2.7.10 |Anaconda 2.3.0 (64-bit)| (default, May 28 2015, 16:44:52)
[MSC v.1500 64 bit (AMD64)]
