Question

# Load the numbers from a file into an array.
def load_numbers(filename):

    numbers = [] # to hold the list of numbers

    try:
        number_file = open(filename, "r")
        for number in number_file:
            number = int(number) # Convert the read string to an int.
            numbers.append(number)
    except Exception as err:
        print ("An error occurred loading", filename)
        print ("The error returned was", err)
        return numbers

    if (len(numbers) < 1):
        print ("There were no numbers in", filename)
        return numbers

    else:
        return numbers

# Perform the statistics calculations using the values
# in the numbers array.

# The main function that contains what the program is to do!
def main():
    do_evaluate = True
    while(do_evaluate):
        filename = input(' What is the file you would like to evaluate? ')
