A programmer has a need to round many numeric values to the nearest integer. Which of the following best explains the benefit of using a list as a data abstraction in this situation

Respuesta :

Answer:

Keeping the numeric values in a list makes it easier to apply the same computation to every data element.

Explanation:

A list or array in programming is a data structure, that has the location for each item it holds indexed. It eliminates the need to constantly create a variable to compute items of the same data types.

The list can store items of the same data type and iterate over them to compute the same calculation on each of them.

Lists are values which are seperated by commas and populated within square brackets. They are mutable and values could be easily accessed, appended, deleted or replaced. Hence, the use of a list for data abstraction is beneficial in that the round function could be easily applied to all the values in the list.

Rounding the values in the list coukd be easily done using for loop which takes each value in the list one at a time, rounds them to the nearest integer and places them into another list.

Using the a python list comprehension thus:

Given a list of numeric Values :

my_list = [1.2, 1.4, 1.5, 1.7]

rounded_int = [round(x) for x in my_list]
