Using single quotes instead of triple double quotes.

Using comments instead of docstrings.

Not enclosing the docstring properly.

The correct docstring uses triple double quotes to properly format the docstring.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that documents word lengths for words longer than 3 characters.

Python

words = ['apple', 'bat', 'carrot', 'dog']
lengths = {word: [1] for word in words if len(word) [2] 3}

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

Alen(word)

B<=

C>

Dword

💡 Hint

Common Mistakes

Using the wrong comparison operator.

Using the word itself instead of its length.

Not filtering words correctly.

The dictionary comprehension uses len(word) to get length and filters words with length greater than 3.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps uppercase words to their lengths if length is greater than 4.

Python

words = ['tree', 'house', 'car', 'elephant']
result = [1]: [2] for word in words if len(word) [3] 4

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

Aword.upper()

Blen(word)

C>

Dword

💡 Hint

Common Mistakes

Using the word itself instead of uppercase.

Using wrong comparison operator.

Mixing keys and values in the comprehension.

The comprehension maps uppercase words to their lengths, filtering words longer than 4 characters.
