8.5 Open the file mbox-short.txt and read it line by line. When you find a line that starts with 'From ' like the following line: From [email protected] Sat Jan 5 09:14:16 2008 You will parse the From line using split() and print out the second word in the line (i.e. the entire address of the person who sent the message). Then print out a count at the end. Hint: make sure not to include the lines that start with 'From:'.

fname = input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"

fh = open(fname)
count = 0
for line in fh:
    x=line.rstrip().split()
    if 'From' in x:
        print(x[1])
        count+=1
    else:
        continue
        
print("There were", count, "lines in the file with From as the first word")

fname = input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"
file = open(fname)
count = 0
for line in file:
if line.startswith("From"):
piece = line.strip().split()
print(piece[1])

print("There were", count, "lines in the file with From as the first word")

I typed this code but it repeats the the mail id if there's multiple. how can i prevent that
