Answer: Python Puzzler #737

The answer is D. The program prints:

56

Why?

range(2, 15, 2) starts at 2, goes up in steps of 2, and stops before 15. So the loop adds 2 + 4 + 6 + 8 + 10 + 12 + 14. The total is 56.

Trace table

A trace table follows the program step by step. Here’s this one:

number	total after the loop body
2	2
4	6
6	12
8	20
10	30
12	42
14	56

The code again

total = 0
for number in range(2, 15, 2):
    total = total + number
print(total)
