Final answer:
The code segment that would complete this function is 'for i in range(start, finish+1, 2)'. This code uses the range() function with a step size of 2 to print every other number from start to finish.
Step-by-step explanation:
The code segment that would complete this function is:
for i in range(start, finish+1, 2)
This code uses the built-in range() function to create a sequence of numbers starting from the 'start' value and ending at the 'finish' value (inclusive). The third argument of range() is the step size, which in this case is 2. This ensures that every other number is printed.
