Dictionary Update Assignment a

Write a program that prompts the user for test scores, stores them in a dictionary, and averages the scores.

$-$ Write a function get$\_$test$\_$scores$()$

$-$ Create an empty dictionary scores$\_$dict $\backslash (=\backslash )$ dict$()$

$-$ Prompt the user to input the number of test scores, store in num$\_$scores

$-$ Write a loop to get each of the num$\_$scores test scores

$-$ Prompt the user to input each test score and store in score. $($Validate the input!$)$

$-$ Add score to scores$\_$dict $\backslash$# HINT: update the dictionary

$-$ Write a second function average$\_$scores$()$ that accepts the dictionary as the only parameter and returns the average scores

$-$ Use len$()$ to determine your num$\_$scores for calculation

$-$ Note a dictionary is a set of key, value pairs.

$-$ You can get the keys with $.$keys$()$ function

$-$ You can access the value using a key variable scores$\_$dict.get$($k$)$

$-$ What about testing?

$-$ Write a main to test your functions

$-$ Unit Tests can also help test average$\_$scores$()$
