Boolean operation
A Boolean operation combines or transforms truth-valued inputs according to logical rules to produce a truth-valued result.
Get Programming: Learn to code with Python
A logical operator is an operator that performs logical combination or negation of Boolean or truthy and falsy operands.
- How it is used
- Combines Boolean conditions to guide program decisions in `if` statements.
- How deep it goes
- Explains operator truth values with a table and shows combined conditions in an `if` statement.
- Examples
- Uses pasta-and-sauce decisions, jacket-or-sweater choices, and negative-number conditions.
- What you can do after
- Apply Boolean operators to combine conditions in Python `if` statements.

Math and Architectures of Deep Learning
A boolean-valued function over logical inputs, such as AND, OR, NOT, or XOR, used here as an example family of functions that can be emulated by perceptrons or MLPs.
- How it is used
- Uses binary decision components to model logical behavior inside larger systems and neural-network function approximators.
- How deep it goes
- Defines binary operations, gives real-world cases, and derives MLP construction from truth-table rows, stopping short of training details.
- Examples
- Uses cat avoidance, vehicle braking, access alarms, friendship recommendations, and an XOR truth table.
- What you can do after
- Build boolean functions from truth tables by decomposing active rows into perceptrons and combining them in an MLP.

100 Java Mistakes and How to Avoid Them
- How it is used
- Uses Boolean-style operators to combine flags, mask bits, and express conditions in Java.
- How deep it goes
- Explains precedence, parentheses, compiler detection, and shift corner cases without deriving Boolean algebra.
- Examples
- Demonstrates masked-bit updates, flag comparisons, negated instanceof conditions, and least-significant-bit masks.
- What you can do after
- Diagnose precedence and shift errors, then prevent them with parentheses, operand checks, and static-analysis rules.

Clojure: The Essential Reference
A boolean operator is an operator or function that combines or transforms truth-valued expressions.
- How it is used
- Uses boolean operations to combine truth values and express short-circuiting decisions, collection-wide tests, and existential searches.
- How deep it goes
- Explains truthiness, predicate contracts, return behavior, accepted collections, and one input exception, but defers comparison details.
- Examples
- Demonstrates positivity tests, negative-number searches, address-book lookup, bingo-card validation, and prize-ticket matching.
- What you can do after
- Apply boolean logic through Clojure operators and collection functions to test conditions or retrieve the first matching result.
