Which statement about the given code is true?

The code will execute the else block if x is less than or equal to 5. (correct)

The code will not execute if x is assigned a value of 5.

The code will always print 'Greater than 5'.

Study Notes

Syntax of if-else Statement in Python

A basic if-else structure consists of a condition followed by two separate code blocks: one for when the condition is true and another for when it is false.

An example of the basic if-else structure is:

if condition:
    # Code to execute if condition is True
else:
    # Code to execute if condition is False

Handling Multiple Conditions

To evaluate more than two conditions, use elif (else if) to define additional conditions.

The structure allows for sequential checks, ensuring that the first true condition executes its corresponding code block:

if condition1:
    # Code for condition1
elif condition2:
    # Code for condition2
else:
    # Code if none of the above conditions are True

Comparison Operators

Logical conditions can incorporate various comparison operators to establish true/false evaluations:
- == checks for equality between two values
- != checks for inequality
- > evaluates whether the left operand is greater than the right
- < assesses if the left operand is less than the right
- >= checks if the left operand is greater than or equal to the right
- <= checks if the left operand is less than or equal to the right
