For Python Intermediate, Object-Oriented Python - Step 2/13: the answer is missing the print(odd_trinum) part.

**EXPECTED:**

tri_num_sequence = [1, 3, 6, 10, 15, 10, 6, 3, 1]

odd_numbers = [1, 3, 5, 7, 9, 11, 13, 15, 17, 19]

trinum_5 = set(tri_num_sequence)

odd_20 = set(odd_numbers)

odd_trinum = set(trinum_5.intersection(odd_20))

print(odd_trinum)

**What DQ.io answer shows:**

tri_num_sequence = [1, 3, 6, 10, 15, 10, 6, 3, 1]

odd_numbers = [1, 3, 5, 7, 9, 11, 13, 15, 17, 19]

trinum_5 = set(tri_num_sequence)

odd_20 = set(odd_numbers)

odd_trinum = set(trinum_5.intersection(odd_20))

Would someone add that in, thank you.
