According

to Herzberg's two-factor theory, satisfiers will make the major difference as

to which brand the customer buys.

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.

A student wants to calculate: 

result = mean([2, 4, 9]) + 1 

They suggest replacing the function’s final line with: 

print(total / len(values)) 

Explain why printing the mean is not a suitable replacement for returning it in this use of the function. [2 marks] 

After a successful call to the original function, a student adds: 

print(total) 

outside the function. 

They argue: “The function has run, so total now exists and can be printed here.” 

Explain why this reasoning is incorrect, and identify which variable outside the function holds the returned mean. [2 marks]
