Need to add a return statement:

In the backwards technique, we work from the end.

We know from the specification that second$\_$in$\_$list is a fruitful function,

so the last thing to do is to return the result.

Add a return statement to the body of second$\_$in$\_$list.

Pick a variable name to return $($other than s$,$ which does not contain the answer$).$

It can be anything you want, though it is standard to name the return variable result.

Do not add any other lines of code to your function body.

Now that you have added this line of code, it is time to run the

test script that we have provided $($always test after you write new code$).$

import introcs

def second$\_$in$\_$list$($s$)$:

$"""$

Returns: the second item in comma$-$separated list

The final result should not have any whitespace around the edges.

Example: second$\_$in$\_$list$(\text{'}$apple$,$ banana, orange'$)$ returns 'banana'

Example: second$\_$in$\_$list$(\text{'}$ do $,$ re $,$ me $,$ fa $\text{'})$ returns $\text{'}$re$\text{'}$

Example: second$\_$in$\_$list$(\text{'}$z$,$y$,$x$,$w$\text{'})$ returns $\text{'}$y$\text{'}$

Parameter s: The list of items

Precondition: s is a string of at least three items separated by commas.
