use repl.it or python3 to write these including the optional one.

Write a utility to convert raw scores into letter grades

1. Write a program to prompt the user to enter a raw score as a decimal (float) 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 [add a personalized statement of encouragement]

Your program should indicate whether the input is bad with Your Name reports data is in incorrect format

Hint: try a nested conditional structure

2. Run the program repeatedly to test the various different values for input to check to see if your program handles bad input correctly.

Ex.

Enter score: 0.95

A

Enter score: perfect

Your Name reports data is in incorrect format

Enter score: 10.0

Your Name reports data is in incorrect format

Enter score: 0.75

C

Enter score: 0.5

F, a personalized statement of encouragement

3. Add comments to your program (using #) that explain what the key lines of your program are doing

4. Optional: to add greater realism and relevance for this class, add plus and minus grades, with a minimum of ._4 for the whole grades and ._7 for the plus grades (the ._0 grades are now minus grades) [earns up to +10% on lab grade]
