### Average3 is renamed to AverageN.
###
### A Variable Number of Parameters is allowed, indicated by the "*" prefix
### for the NumbersParameter.
### 
### The variable *Numbers is used as a List to construct a For Loop to sum all Arguments.
###
### Note that the built in Function "len" works on Lists (and tuples),
### returning the Number of List elements.
### 
### return the Sum of all the Arguments, divided by the Number of Arguments ... also known
### as "The Average".

    Total = 0 # Initialise Variable to store the Sum of all Arguments.

    for Number in Numbers: # For each Argument,
        Total += Number    # increment the Total.

    return (Total / len(Numbers))  # Return the Average.
