4.10. Glossary¶
- Body¶
The sequence of statements within a compound statement.
- Boolean Expression¶
An expression whose value is either
TrueorFalse.- Branch¶
One of the alternative sequences of statements in a conditional statement.
- Chained Conditional¶
A conditional statement with a series of alternative branches.
- Comparison Operator¶
One of the operators that compares its operands:
==,!=,>,<,>=, and<=.- Conditional Statement¶
A statement that controls the flow of execution depending on some condition.
- Condition¶
The boolean expression in a conditional statement that determines which branch is executed.
- Compound Statement¶
A statement that consists of a header and a body. The header ends with a colon (:). The body is indented relative to the header.
- Guardian Pattern¶
Where we construct a logical expression with additional comparisons to take advantage of the short-circuit behavior.
- Logical Operator¶
One of the operators that combines boolean expressions:
and,or, andnot.- Nested Conditional¶
A conditional statement that appears in one of the branches of another conditional statement.
- Traceback¶
A list of the functions that are executing, printed when an exception occurs.
- Short Circuit¶
When Python is part-way through evaluating a logical expression and stops the evaluation because Python knows the final value for the expression without needing to evaluate the rest of the expression.
