Boolean Data TypeΒΆ
In computer programming, a boolean data type is a data type that
can have one of two values which are usually denoted as true
and false. In Python the syntax for these two values are True
and False. These two values are built into the Python
programming language and are of type boolean or bool
for short.
Create a new Jupyter Notebook and call it booleans_comparison_logical_operators. Type out the code as you read and go through this. Play around with code because it will help you to learn!

They are case sensitive. If you try writing for example, true, or FALSE, or some variation
you will get an error.
So why is this important? Well, often programs are made up
of lots of tiny decisions that depend on various outcomes.
For example, you might want to perform some logic if something is True
or perform different logic if something is False. This is why
boolean data types are so important.
You may be wondering how does something evaluate to True or False?
To start learning more about this we are going to introduce
the Python comparision operators.
