You can download the sample data at  http://www.py4e.com/code3/mbox-short.txt Solution:- fname =input("Enter file name: ") fh = open(fname) count = 0 for line in fh:     line = line.rstrip()     if not line.startswith('From '):         continue     words = line.split()     print (words[1])     count += 1 print ("There were", count, "lines in the file with From as the first word") Cou...

Coursera : Python data structures Assignment 8.4 Week 4 8.4  Open the file  romeo.txt  and read it line by line. For each line, split the line into a list of words using the  split()  method. The program should build a list of words. For each word on each line check to see if the word is already in the list and if not append it to the list. When the program completes, sort and print the resulting words in alphabetical order. You can download the sample data at  http://www.py4e.com/code3 Solution: fname = input("Enter file name: ") fh = open(fname) lst = list() for line in fh:     for i in line.rstrip().split(' '):         lst.append(i) lst = list(set(lst)) lst.sort() print(lst) Coursera official website: https://www.coursera.org/learn/python-data/home/welcome
