Create a python program that asks the user for the daily sales for each day of a seven day week, beginning on Sunday. Make sure these are stored in a list. Using separate functions, calculate the sum and average of the daily sales and then display them with proper labels.

$-$ Each function must have one responsibility.$$ Yes, these programs should use functions.

$-$ You can pass lists as arguments to functions.

$-$ A list can be changed inside a function.

$-$ If you have to keep values together, you can use a list like a record and then make a list of lists to keep all the records.
