word4 = "no"
word5 = "play"
word6 = "makes"
word7 = "Jack"
word8 = "a"
word9 = "dull"

2.A program that will compute MPG for a car. Prompt the user to enter the number of miles driven and the number of gallons used. Print a nice message with the answer. For stye points, cue the message printed off of how efficient (or not) the car is.
Code:

11
12
mile = int(raw_input("Please enter the number of miles driven?"))
gallon = int(raw_input("Please enter the number of gallons used?"))
mpg = mile / gallon
print "You entered miles: ", mile
print "You entered gallons: ", gallon
print "The mpg: ", mpg
if mpg > 25:
print "Congratuation, you got a efficient car!"
else: print "Your car is not a efficient car!"
Output:
1
2
3
4
You entered miles: 150
You entered gallons: 5
The mpg: 30.0
Congratuation, you got a efficient car!
3. A program that will convert a user-input number of degrees celsius to degrees fahrenheit.
Code:
1
2
3
4
5
6
deg_c = int(input("What is the temperature in Celsius? "))
# formula to convert C to F is: (degrees Celcius) times (9/5) plus (32)deg_f = deg_c * (9 / 5) + 32
print (deg_c, "degrees Celsius is", deg_f, "degrees Farenheit.")
Output:
1
15 degrees Celsius is 59 degrees Farenheit.
4.A program that will convert a user-input number of degrees degrees fahrenheit to degrees celsius.
Code:
1
2
3
4
5
deg_f = int(input("What is the temperature in Farenheit? "))
deg_c= (deg_f - 32)/ 1.8
print (deg_f, "degrees Farenheit is", deg_c, "degrees Celsius.")
Output:
1
59 degrees Farenheit is 15 degrees Celsius.
5.A program that will convert degrees or celsius as above, depending on the users' choice.
Code:

flag = raw_input('If convert C to F, please enter "y", if convert F to C, please enter"n".')
if flag == "y":
deg_c = int(input("What is the temperature in Celsius? "))
# formula to convert C to F is: (degrees Celcius) times (9/5) plus (32) deg_f = deg_c * (9 / 5) + 32
print deg_c, "degrees Celsius is", deg_f, "degrees Farenheit."
elif flag == "n":
deg_f = int(input("What is the temperature in Farenheit? "))
deg_c= (deg_f - 32)/ 1.8
print deg_f, "degrees Farenheit is", deg_c, "degrees Celsius."
else : print "Wrong Input"
Output:
If you enter y and the temperature in Celsius:
1
15 degrees Celsius is 59 degrees Farenheit.
If you enter y and the temperature in Farenheit:
1
59 degrees Farenheit is 15 degrees Celsius.
If you enter other characters:
1
Wrong Input
