# Functions and Lists Mixed-Up Code QuestionsΒΆ

Create a function called `second_half`

that takes in `lst`

as a parameter and returns the second half of `lst`

.
For example, `second_half([1])`

should return `[1]`

, `second_half([1, 2, 3])`

should return `[2, 3]`

, and `second_half([1, 2, 3, 4])`

should return `[3, 4]`

.

as a parameter and returns the second half of `lst`

.
For example, `second_half([1])`

should return `[1]`

, `second_half([1, 2, 3])`

should return `[2, 3]`

, and `second_half([1, 2, 3, 4])`

should return `[3, 4]`

.

Create a function called `sum_of_split_num`

that takes in `str_num_with_hyphens`

as a parameter and returns the sum of the integers that
are split up by hyphens. For example, `sum_of_split_num('978-876-4908')`

should return `6762`

because 978 + 876 + 4908 = 6762.
(Note: Integers are 0 or greater.)

Create a function called `sort_descending`

that takes in `lst_of_nums`

as a parameter and returns `lst_of_nums`

in descending order.
For example, `sort_descending([100, 2000, -50])`

should return `[2000, 100, -50]`

.

should return `[2000, 100, -50]`

.

Create a function called `extend_two_lists_sort`

that takes in `lst1`

and `lst2`

as parameters, sorts both lists, and extends `lst1`

with `lst2`

.
For example, `extend_two_lists_sort(['string', 'hello'], ['my', 'goodness'])`

should return `['hello', 'string', 'goodness', 'my']`

.

.

Create a function called `sort_and_get_median_num`

that takes in `lst_of_nums`

as a parameter, sorts `lst_of_nums`

, and returns the median
of `lst_of_nums`

. For example, `sort_and_get_median_num([200, -5, 0, 75, 80, 60])`

should return `67.5`

, and
`sort_and_get_median_num([200, -5, 0, 75, 80])`

should return `75`

.
