Perform the following steps in the file you created above (lastname_firstname_lab4.py):

Create a program to calculate statics for quarterly sales

Specifications:

Create a function to display the "Header/Greeting"

Create a function named "get_quarterly_sales()" to ask the user to input a numeric value for each quarters sales totals. Store the information in a List. The function should return the list

Create a function named "process_sales()" to process the sales data and display information about the sales figures. The function should take a single list as a parameter and then do the necessary calculations to be able to print the "Total, Average, Maximum, and Minimum values" as shown in the sample output below

Create a Main function to call these functions in order. Note you'll need to store the returned value from the get_quarterly_sales() function in order to pass it as a parameter to the process_sales() function.

Sample input / output:
