This week you will create a program which has a variety of functions and will demonstrate your usage of loops. You will use both a while loop and a for loop for this assignment.Your program must have a header. Your program should adhere to PEP$8$ guidelines especially as it pertains to variable names.This program will perform various calculations $($addition$,$ subtraction, multiplication, division, and average calculation$)$This program will contain a variety of loops and functions.The program will add, subtract, multiply, divide two numbers and provide the average of multiple numbers input by the user.Define a function named performCalculation which takes one parameter. The parameter will be the operation being performed $(+,-,*,/).$This function will prompt the user user for two numbers then perform the expected operation depending on the parameter that's passed into the function.This function will print the calculated value for the end user.Define a function named calculateAverage which takes no parameters.This function will ask the user how many numbers they wish to input.This function will use the number of times to run the program within a for loop in order to calculate the total and average.This function will print the calculated average.This program will have a main method which contains a while loop. The while loop will be used to allow the user to run the program until they enter a value which ends the loop.The main method should prompt the user for the operation they wish to perform.The main method should evaluate the entered data using if statements. The main method should call the necessary function to perform the calculation.
