To write a program that keeps names and email addresses in a dictionary as key-value pairs check the code given below.

<h3>What is key-value pairs?</h3>

In a key-value pair, two related data elements are combined: a value, which is a variable that belongs to the set (for example, male/female, green, 100), and a key, which is a constant that defines the data set (for example, gender, color, price).

A key-value pair could look something like this when fully formed:

gender = male

color = green

price > 100
