将元素列表组合到元组列表

Question

How can I combine a List of elements with a List of Tuples (as shown below)?如何将元素列表与元组列表结合起来（如下所示）？

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

Expected output:预期 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:使用扩展的可迭代解包来构建预期结果的元组：

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

Output Output

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

As an alternative, use:作为替代方案，请使用：

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