This is a list within a list problem. Write a Python program to do the following:Calculate the average for a list of numbersUse a for loop to iterate through the weekly$\_$sales list, and calculate the average sales number and printthe name of the sales person followed by the average.Here is the sales summary to use as input:weekly$\_$sales $=[[\text{'}$John Sellall', $[10000,9250,1900,8009,8059,7500]],[\text{'}$Sarah Marketer', $[9990,9120,6100,10000,8500,9900]],[\text{'}$Frank Deal', $[7500,7055,10000,8020,8500,9100]],[\text{'}$Bill Discount', $[9500,7000,1100,8500,9000,7050]],[\text{'}$Betty Budget', $[10000,10000,11100,12000,10000,9900]],[\text{'}$Charles Closing', $[8800,8500,8370,9000,7900,9100]]]$Your output should look like this:John Sellall $7453$Sarah Marketer $8935$Frank Deal $8362$Bill Discount $7025$Betty Budget $10500$Charles Closing $8612$Basically all you need is a for loop that loops through weekly$\_$sales, gets the average and prints the name and the average. You can use sum, len, and round to do that.
