Python List Assignment 8.5.py

""" Assignment 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 stephen.marquard@uct.ac.za 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:'. Also look at the last line of the sample output to see how to print the count.

You can download the sample data at http://www.py4e.com/code3/mbox-short.txt  """

givenFile = input("Enter file name: ") # user input
givenFile  = open(givenFile)  # open file
count = 0   # counter
for line in givenFile :    # iterate over the file
  line = line.rstrip()    # remove spaes
  if not line.startswith('From '): continue
  count += 1   # increment counter by one 
  words = line.split()  # split line to small words
  print(words[1])   # print the second word in the line

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