7.9. Glossary
- block
- A group of consecutive statements with the same indentation.
- body
- The block of statements in a compound statement that follows the
header.
- boolean expression
- An expression that is either true or false.
- boolean function
- A function that returns a boolean value. The only possible
values of the
bool
type are False
and True
.
- boolean value
- There are exactly two boolean values:
True
and False
. Boolean
values result when a boolean expression is evaluated by the Python
interepreter. They have type bool
.
- branch
- One of the possible paths of the flow of execution determined by
conditional execution.
- chained conditional
- A conditional branch with more than two possible flows of execution. In
Python chained conditionals are written with
if ... elif ... else
statements.
- comparison operator
- One of the operators that compares two values:
==
, !=
, >
,
<
, >=
, and <=
.
- condition
- The boolean expression in a conditional statement that determines which
branch is executed.
- conditional statement
- A statement that controls the flow of execution depending on some
condition. In Python the keywords
if
, elif
, and else
are
used for conditional statements.
- logical operator
- One of the operators that combines boolean expressions:
and
,
or
, and not
.
- modulus operator
- An operator, denoted with a percent sign (
%
), that works on
integers and yields the remainder when one number is divided by
another.
- nesting
- One program structure within another, such as a conditional statement
inside a branch of another conditional statement.
