Please help,   So below is the question of the problem for my class.  I have attached a picture of my python program and I keep getting than error message.  I have also attached the list of the friends and age. using python Now write a program named filereader.py that reads and displays the data in friends.txt. This program should also determine and print the average age of the friends on file. That will require an accumulator and a counter. Use a while loop to process the file, print the data, and modify the accumulator and counter. Then close the file and display the average age accurate to one decimal place. See the Sample Output..SAMPLE OUTPUT My friend Denny is 24My friend Penny is 28My friend Lenny is 20My friend Jenny is 24Average age of friends is 24.0   I appreciate the help Kevin

From a list of numbers, calculate the average. The length of the list will vary. -99 will signal the end of the valid input. (Python) Input Format Inputs will be whole numbers. Sample input: 80 90 75 95 -99 Constraints Do not use any functions besides int, input, and print. There will always be at least one valid number input. Output Format Just output the average. Sample output: 85.0 Sample Input 0 80 90 75 95 -99 Sample Output 0 85.0

Design a modular program in Python to process payroll for all hourly paid employees, save all the data into a text file and make a backup file as well. The program should allow user enter each employee's ID, name, hours worked, and hourly pay rate. And then calculate gross pay with overtime hours(hours beyond 40) paid 50% more. And then the program should display pay statement for each employee and store them into a same text file. The program should display total number of employees, total number of hours worked by all employees, and total gross pay and save them at the end of the same text file as well. The program should contain the following functions: main(), get_employee_info(), calc_gross_pay(hours, rate), display_pay_statement(emp_id, emp_name, hours_horked, hourly_pay_rate, gross_pay), save_pay_statement_to_file(file_object, emp_id, emp_name, hours_worked, hourly_pay_rate, gross_pay), save_summary_to_file(file_object, number_of_employees, total_hours_worked, total_gross_pay).…
