Chapter Exercises -

Make a .py file called Ex3_1. Then, 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 (5 pts):

Score Grade

>= 0.9 A

>= 0.8 B

>= 0.7 C

>= 0.6 D

< 0.6 F

~~~

Sample output:

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.

Make a .py file called Ex3_2. Then, write a program to prompt a user for a positive integer using input(). Be sure to make sure the number is an int using int(). If the number is NOT an int, use try/except to tell the user to enter an int and get the input again. If the user fails to enter an int the SECOND time, gracefully exit (Goodbye User/Youre a jerk, user/etc).
