Python Decision Structures Quiz

Operators and Variables

• The relational operator is used to determine if a specific relationship exists between two values.
• A boolean variable references one of two values, True or False.

Decision Structures

• The syntax for a dual alternative decision structure in Python uses the if and else keywords.
• The first line of an if statement in Python is known as the condition or conditional expression.
• The keyword if signifies the start of a conditional statement in Python syntax.
• A diamond shape in a flowchart represents a decision or conditional statement.

Conditional Execution

• If the condition in an if statement is false and there is no else clause, the program will simply skip the if block and continue executing the rest of the code.
• A flag is used in programming to control the flow of a program's execution.
• A boolean variable is used to control the flow of a program's execution.

Flowcharts and Control Structures

• A diamond in a flowchart represents a decision or conditional statement.
• A control structure refers to a logical design that controls the order in which a set of statements execute.
• A decision structure provides two or more alternative paths of execution.
• A conditional structure allows actions to be performed only when a specified condition is true.
• A conditional structure is used to perform a specific action only if a condition exists.

Comparisons and Operations

• The result of the expression $10 = x < 20 is True if x is between 10 and 20, and False otherwise.
• String comparisons using relational operators are case sensitive when comparing strings.
• Relational operators determine if a specific relationship exists between two values.
