Say I have the following lists:
list_a = [1, 4, 7]
list_b = [(2, 3), (5, 6), (8, 9)]
How do I combine them so that it becomes
[(1, 2, 3), (4, 5, 6), (7, 8, 9)]

Do you mean that you can't use the `zip` function? – mkrieger1 Feb 03 '23 at 23:10

2`[(a,) + b for a,b in zip(list_a, list_b)]` – Mark Tolonen Feb 03 '23 at 23:11

You can expand the tuple in the second zipped item to build a final tuple
list_a = [1, 4, 7]
list_b = [(2, 3), (5, 6), (8, 9)]
print([(a,*b) for a,b in zip(list_a, list_b)])
Output
[(1, 2, 3), (4, 5, 6), (7, 8, 9)]

list_a = [1, 4, 7]
list_b = [(2, 3), (5, 6), (8, 9)]
# FOR LIST_A TO B
for i in range(len(list_a)):
a = list_a[i]
test = list_b[i] + (a,)
print(test)
