Define a function list$\_$sum$()$ that takes three arguments: a list $L,$ a start index s$\_$idx

and and end index eids. The function assumes that the list contains numbers either of type float. The

function returns the sum of the values between index s$\_$idx and c$-$idx inclusive. You do not need to write

code to call the function, you only need to define the function. You must include a docstring and

parameter annotations to demonstrate proficiency on this standard.

The following are examples of calling the function:

$1$st$\_$sum $([1,6,7,8,5,4,5],2,5)$

$24$

$)$ list$\_$sum $([1,1,1,1,1],0,4)$

$5$
