💡 Hint

Common Mistakes

Forgetting to put quotes around the text.

Using unquoted text which causes a NameError.

In Python, strings must be enclosed in quotes. Using quotes around 'Hello, world!' makes it a string literal that print() can output.

💡 Hint

Common Mistakes

Putting quotes around numbers, making them strings.

Using words instead of digits for numbers.

To assign a number, write the number without quotes. Quotes make it a string, which is different from a number.

Fix the error in the interactive mode code to correctly print the sum of 2 and 3.

Python

print([1])

Drag options to blanks, or click blank then click option'

A2 + 3

B"2 + 3"

C2 plus 3

Dsum(2, 3)

💡 Hint

Common Mistakes

Putting the expression inside quotes, which prints text instead of calculating.

Using incorrect function calls like sum(2, 3) which causes errors.

In interactive mode, you can write expressions like 2 + 3 directly to get the result 5. Using quotes prints the text, not the sum.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that includes only even numbers from 1 to 5.

Python

evens = {x: x[1]2 for x in range(1, 6) if x [2] 2 == 0}

Drag options to blanks, or click blank then click option'

A**

B%

C//

D+

💡 Hint

Common Mistakes

Using + instead of ** for squaring.

Using // instead of % for checking even numbers.

The expression x**2 squares x. The condition x % 2 == 0 checks if x is even by seeing if the remainder when divided by 2 is zero.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that converts keys to uppercase, keeps values, and filters values greater than 0.

Python

result = { [1]: [2] for k, v in data.items() if v [3] 0 }

Drag options to blanks, or click blank then click option'

Ak.upper()

Bv

C>

Dk

💡 Hint

Common Mistakes

Using k instead of k.upper() for keys.

Using < instead of > for filtering values.

k.upper() converts keys to uppercase. We keep the value v as is. The condition v > 0 filters only positive values.
