Exercise 1. Advanced pay computation (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. Advanced pay computation (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 (use the command raise instead of quit() ). 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. Convert scores to grades

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.

Exercise 4. Check the age of your participant

Write a program to prompt a user for their name and age. If the person is younger than 18 provide a message that the person is too young. If the person is older than 30 provides a message that the person is too old. If the value is between 18 and 30, provide a personalized welcome message, that says “Hello xx, welcome to this experiment.” (replace the xx).
