Combining Lists of elements to List of Tuples

Question

How can I combine a List of elements with a List of Tuples (as shown below) ?

a = ['x', 'y', 1234]
b = [('Broad Street', 'NY'), ('Park Street', 'CA')]

Expected output:

[('x', 'y', 1234, 'Broad Street', 'NY'), ('x', 'y', 1234, 'Park Street',  'CA')]

Answer 1

Use extended iterable unpacking to build the tuples of the expected result:

res = [(*a, *bi) for bi in b]
print(res)

Output

[('x', 'y', 1234, 'Broad Street', 'NY'), ('x', 'y', 1234, 'Park Street', 'CA')]

As an alternative, use:

tuple_a = tuple(a)
res = [tuple_a + bi for bi in b]
