Booleans

Booleans can have only one of two values: either False or True. They are used to describe logical operations, for example, tests or conditions. There are a few operations that result in Boolean values:

• First, you can use the equality test for any type of data:

>>> 'World' == 'World'True >>> pi == piTrue

• In the previous section, we ran into another example, which was inclusion test:

>>> “World” in “Hello World!”True

• != is the opposite of equal, not equal:

>>> pi != piFalse

There are more test operators, including greater than (>), less than (<), greater than or equal to (>=), less than or equal to (<=), and nonequal (<>). Those tests will also work with strings by comparing them lexicographically. Python will compare the order ...
