Purpose of if statements:

when you need to make decisions/choices in your program, allows you to execute the code only if the statement is true.

for or they have to be?

Only ONE Of them has to be true.

What is the purpose of an elif statement?

It allows you to check multiple conditions after an initial if. Only the first true elif block will execute.

What happens if none of the if or elif conditions are true and there is no else?

The program simply skips the conditional block and continues with the rest of the code.

What is the difference between = and ==?

= assigns a value to a variable, while == checks if two values are equal.

How can you combine multiple conditions in one if statement?

Using logical operators like and, or, and not.

What does the not operator do in a conditional?

It reverses the Boolean value (True becomes False, False becomes True).

True or False: The code inside an if block will always run.

False. It only runs if the condition is True.

Can you write an if statement without elif or else?

Yes. elif and else are optional.

What is short-circuit evaluation in Python?

In and or or statements, Python stops evaluating as soon as the outcome is determined.

Which operator has higher precedence: and or or?

and has higher precedence than or.

What is a nested if statement?

An if statement placed inside another if statement; allows checking multiple layers of conditions.

in and not inWhat does the in operator do?

Checks if a value exists in a sequence

How do you check if "banana" is NOT in a list ["apple", "orange", "grape"]?

"banana" not in ["apple", "orange", "grape"]
