Python Lists, Dictionaries, and Sets

Overview

A data structure is a way of organizing, managing, and storing data that allows efficient modification and access. Different data structures support different functions more efficiently than others. The data structure represents a group of data values, relationships between the values, and the operations and functions that can be used with the data. An example of how a data structure is used is the use of a b-tree index data structure for retrieving data from a relational database. A hash table data structure is used to look up identifiers.

In this assignment you create three data structure types and populate them with data.

Exercise 1 - Create a List to Sum Values

Write a script that sums the values in a list called add_list that contains the following values: (10, 2, -4, 8). Make sure you include a for loop when iterating through the list to sum the values.

Take screenshots of the code and output.

Exercise 2 - Create a Dictionary

Write a script that prints a dictionary where the key numbers are 1, 2, 3, 4, and 5 and the values are the key number times 2. Be sure to use an appropriate loop to iterate through the dictionary when printing the dictionary.

Take a screenshot of your code and the output.

Exercise 3 - Sets and Set Operations

Imagine you have two grocery lists:

Write scripts that do the following:

1.Prints names of products common to both lists.

2.Prints names of products that are in at least one of the two lists.
