# Introduction

Python represents true and false values with the `bool` type.
 There are only two values under that type: `True` and `False`.
  These values can be bound to a variable:

```python
>>> true_variable = True
>>> false_variable = False
```

We can evaluate Boolean expressions using the `and`, `or`, and `not` operators.

```python
>>> true_variable = True and True
>>> false_variable = True and False

>>> true_variable = False or True
>>> false_variable = False or False

>>> true_variable = not False
>>> false_variable = not True
```
