The following template is a program implementing a dictionary in Python where the keys are a couple of countries. The values are their corresponding capitals. Within the notebook, it is demonstrated how to retrieve keys and values from the dictionary, how to create a new key: value pair and how to loop through the keys and the values using a for-loop.

Who is it for?
Machine Learning Engineers, Data Scientists, Data Analysts, Data Architects, and BI Developers and anyone who wants to organize data using key: value pairs will find this free template helpful.
How can it help you?
Dictionaries are a very useful datatype that helps organize data using key:value pairs. Each value could consist of one or more items - this divides dictionaries into one- and multi-dimensional ones. This template gives an example of a one-dimensional dictionary storing countries as keys and their respective capitals as values.
