Consider: 

def mean(values): 

    """Return the arithmetic mean of the supplied values.""" 

    total = 0 

    for value in values: 

        total = total + value 

    return total / len(values) 

result = mean([2, 4, 9]) 

print(result) 

State the exact printed output. In your explanation, identify: 

• the value supplied to values;
• the final value of total;
• what len(values) returns.
