Submit a well-formatted pull request to our class blog with embedded Trinket programs for the below three exercises from Chapter 3 (use these instead of the ones in the book - I added a few explanations). Complete these on your own, using only the materials in this Chapter. Do not look at other students’ submissions until after you’ve completed your work.

After your programs are done, check other students’ work and other resources online if you had questions. Include a reflection about what you think you’ve learned and any concepts that are still fuzzy to you. Did you encounter frustrating situations? Did you feel a lightbulb turn on?

Exercise 1: Rewrite your pay computation to give the employee 1.5 times the hourly rate for hours worked above 40 hours.

Enter Hours: 45
Enter Rate: 10
Pay: 475.0

Exercise 2: Rewrite your pay program using try and except so that your program handles non-numeric input gracefully by printing a message and exiting the program. The following shows two executions of the program:

Enter Hours: 20
Enter Rate: nine
Error, please enter numeric input

Enter Hours: forty
Error, please enter numeric input

Exercise 3: Write a program to prompt for a score between 0.0 and 1.0. If the score is out of range, print an error message. 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

Enter score: 0.95
A

Enter score: perfect
Bad score

Enter score: 10.0
Bad score

Enter score: 0.75
C

Enter score: 0.5
F

Run the program repeatedly as shown above to test the various different values for input.
