Simple Python program to read 'n' numbers from users and calculate the average of those numbers.

 

def calculate_average(numbers):

    return sum(numbers) / len(numbers) if numbers else 0

def main():

    # Read the number of values

    n = int(input("Enter the number of values: "))

   

    if n <= 0:

        print("The number of values should be greater than 0.")

        return

   

    numbers = []

   

    # Read n numbers from the user

    for i in range(n):

        while True:

            try:

                number = float(input(f"Enter number {i + 1}: "))

                numbers.append(number)

                break

            except ValueError:

                print("Invalid input. Please enter a valid number.")

   

    # Calculate and display the average

    average = calculate_average(numbers)

    print(f"The average of the entered numbers is: {average:.2f}")

if __name__ == "__main__":

    main()
