Python Function to Calculate Average of List Numbers

Here's a Python function that calculates the average value of a given list of numbers, including handling empty lists to prevent division by zero errors:

def compute_average(numbers):
    if len(numbers) == 0:
        return 0  # Return 0 if the list is empty to avoid division by zero error
    total = sum(numbers)
    average = total / len(numbers)
    print('The average value is:', average)
    return average

You can use this function by passing a list of numbers as an argument. For example:

my_list = [1, 2, 3, 4, 5]
compute_average(my_list)

Output:

The average value is: 3.0

This function gracefully handles the scenario where the input list is empty by returning 0, preventing any division by zero errors. This makes it a robust and reliable solution for calculating the average of a list of numbers in Python.
