CSIT111 Decisions and Conditionals Quiz Ultimate Study Guide

Boolean

A data type that has two possible values: True and False.

Truthy Value

A value that evaluates to True in a conditional context.

Falsy Value

A value that evaluates to False in a conditional context.

Comparison Operators

Operators that compare two values and return a Boolean result, such as ==, !=, >,

if Statement

A control structure that executes a block of code if its condition evaluates to True.

else Statement

A control structure that executes a block of code if the preceding if condition evaluates to False.

elif Statement

A control structure that provides an additional condition to test if the preceding if condition was False.

Logical Operators

Operators that combine conditional statements: and (both must be True), or (at least one must be True), not (inverts the Boolean value).

Ternary Operator

A concise way to write an if-else statement in a single line, formatted as: value_if_true if condition else value_if_false.

Operator Precedence

The rules that determine the order in which operations are performed in expressions.

Nested Decisions

When an if statement contains another if statement within its block, requiring multiple conditions to be checked.

Chained Decisions

Multiple if statements joined with elif, allowing for more than two possible execution paths.

SyntaxError

An error that occurs when the code is not properly formatted according to Python syntax rules.

IndentationError

An error that occurs when there is inconsistent or incorrect use of indentation in Python.

Control Flow

The order in which individual statements, instructions, or function calls are executed in a program.

bool() Function

A built-in function that converts a value to a Boolean (True or False) based on its truthiness.

Type Casting

The process of converting one data type into another, such as converting a string to an integer.

Execution Path

The specific sequence of executed code based on conditional tests.

Input Conversion Trap

The scenario where input from the user is treated as a string, even if it represents a number, unless explicitly converted.

Boolean Evaluation.

Determining the truth value of an expression using Boolean logic.

Short-Circuit Evaluation

The process where Python evaluates conditions only as far as necessary, stopping early if the result is determined.
