Problem 1

Write a program called hw2_1.py that displays a table of temperatures, the left column in Fahrenheit, and the right column in Celsius. The program asks the user for two numbers, a temperature T, and a number of temperatures n, and displays a conversion table showing n lines of temperature conversions.

Here is an example of how your program should work (the user input is in boldface):

Please enter the starting temperature:  30
How many lines do you want for the table?  10
 
30         -1.11111111111
31         -0.555555555556
32         0.0
33         0.555555555556
34         1.11111111111
35         1.66666666667
36         2.22222222222
37         2.77777777778
38         3.33333333333
39         3.88888888889

And here is another example:

Please enter the starting temperature:  32
How many lines do you want for the table?  4
 
32         0.0
33         0.555555555556
34         1.11111111111
35         1.66666666667

• Submit your program on Moodle, in the HW2 PB1 section.

Problem 2

Write a program called hw2_2.py that displays a table of temperatures, the left column in Fahrenheit, and the right column in Celsius. The program asks the user for three numbers:

• a temperature T,
• a number of temperatures n,
• and the step used to skip temperatures.

If the user enters 1 for the step, the output of this program will be the same as the output of the solution program for Problem 1.

Note: we assume that the step will always be positive.

Here is an example of how your program should work (the user input is in boldface):

Please enter the starting temperature:  30
How many lines do you want for the table?  5
What step should be used? 2 

30         -1.11111111111
32         0.0
34         1.11111111111
36         2.22222222222
38         3.33333333333

And here is another example:

Please enter the starting temperature:  38
How many lines do you want for the table?  4
What step should be used? 2 
 
38         3.33333333333
37         2.77777777778
36         2.22222222222
35         1.66666666667

• Submit your program on Moodle, in the HW2 PB2 section.
