Logical operators are used to check the logical truthfulness in one or multiple statements. Python support these three logical operators:

**And (and) operator**

The 'and' logical operator evaluates two expressions and return True is and only if both expressions are True. Examples:

`print (2 < 3 and 4 < 5)`

will output True since 2 is less than 3 and 4 is less than 5.

`print (2 > 3 and 4 < 5)`

will output False since one of the expressions (2 > 3) evaluates to False.

**Or (or) operator**

The 'or' logical operator evaluates two expressions and return True is at least one of the expressions is True. So

`print (2 > 3 or 4 < 5)`

will evaluate to True since the right expression (4 < 5) evaluates to True.

**Not (not) operator**

The 'not' logical operator is a unary operator (operator with only one operand) that complements an operand. Example

```
x = True
print (not x)
```

will output False since the complement of True is False.
