Knowledge Check: Module 8

Instructions:

Answer the following 10 multiple-choice questions.

You need to answer at least 6 questions correctly to pass this knowledge check.

You can attempt this check as many times as you need.

1. Which keyword is used in Python to check an additional condition *only if* the preceding `if` condition was false?

else

elif

if else

otherwise

2. Consider the code:

temp = 25
if temp < 0:
    print("Freezing")
elif temp < 20:
    print("Cool")
elif temp < 30:
    print("Warm")
else:
    print("Hot")

What will be printed?

Cool

Hot

Warm

Cool Warm

3. In an `if`/`elif`/`else` structure, how many blocks of code can be executed at most?

Only one

One or more, depending on the conditions

All blocks whose conditions are true

Zero, if none of the conditions are met (and there's no else)

4. What is the primary role of the `else` block in an `if`/`elif`/`else` chain?

To provide an alternative condition to check.

To always execute after the `if` or `elif` blocks.

To repeat the last `elif` check.

To execute code only when all preceding `if` and `elif` conditions are false.

5. Can you have multiple `elif` statements following a single `if` statement?

No, only one `elif` is allowed.

Yes, you can have as many `elif` statements as needed.

Yes, but only if there is no `else` statement.

Only two `elif` statements are allowed.

6. What is required immediately after the condition in an `elif` statement?

A semicolon (`;`)

Parentheses `()` around the condition

A colon (`:`)

The keyword `then`

7. Consider this code:

score = 75
if score >= 90:
    grade = 'A'
elif score >= 80:
    grade = 'B'
elif score >= 70:
    grade = 'C'
else:
    grade = 'D'
print(grade)

What will the output be?

8. Is an `else` block mandatory when using `if` and `elif`?

Yes, `else` must always be included.

Yes, but only if you have more than one `elif`.

Yes, unless the `if` condition is always true.

No, the `else` block is optional.

9. What happens if the code inside an `elif` block is not indented correctly?

The code runs, but might produce unexpected results.

Python will raise an `IndentationError`.

The `elif` block is simply ignored.

The `else` block (if present) will execute instead.

10. If you have `if condition1: ... elif condition2: ... else: ...`, and both `condition1` and `condition2` are `True`, which block's code will execute?

Only the code block under `if condition1:`

Only the code block under `elif condition2:`

Both the `if` and `elif` code blocks.

The code block under `else:`.
