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 c…

	fname = input("Enter file name: ")
	fh = open(fname)
	count = 0
	for line in fh:
	line=line.rstrip()
	if line.startswith('From:'):
	continue
	if not line.startswith('From'):
	continue
	words=line.split()

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 alp…

	fh = open(fname)
	lst = list()
	for line in fh:
	line=line.rstrip()
	words=line.split()
	for word in words:
	if not word in lst:
	lst.append(word)
	else:

Write a program that repeatedly prompts a user for integer numbers until the user enters 'done'. Once 'done' is entered, print out the largest and smallest of the numbers. If the user enters anything other than a valid number catch it with a try/except and put out an appropriate message and ignore the number.

	largest = None
	smallest = None

	while True:

	try:
	num = input("Enter a number: ")
	if num == "done":
	break
	n=int(num)

Write a program to prompt the user for hours and rate per hour using input to compute gross pay. Pay should be the normal rate for hours up to 40 and time-and-a-half for the hourly rate for all hours worked above 40 hours. Put the logic to do the computation of pay in a function called computepay() and use the function to do the computation. The…

	if h>40:
	p=(1.5(h-40)r)+(40*r)
	else:

som983 / Write a program to prompt for a score between 0.0 and 1.0. If the score is out of range, print an error. If the score is between 0.0 and 1.0, print a grade using the following table: Score Grade >= 0.9 A >= 0.8 B >= 0.7 C >= 0.6 D < 0.6 F
