💡 Hint

Common Mistakes

Passing the function name 'sorted' instead of the list variable.

Passing 'list' or 'range' which are not the list to sort.

The sorted() function takes an iterable like a list and returns a new sorted list. Here, we pass the list numbers to it.

Complete the code to sort the list in descending order.

Python

fruits = ['banana', 'apple', 'cherry']
sorted_fruits = sorted(fruits, [1]=True)
print(sorted_fruits)

💡 Hint

Common Mistakes

Using 'key=True' which is incorrect.

Using 'order=True' or 'descending=True' which are not valid parameters.

The sorted() function has a reverse parameter. Setting reverse=True sorts the list in descending order.

Fix the error in the code to sort words by their length.

Python

words = ['cat', 'elephant', 'dog']
sorted_words = sorted(words, key=[1])
print(sorted_words)

💡 Hint

Common Mistakes

Using 'length', 'size', or 'count' which are not built-in functions.

The key parameter expects a function. The built-in function len returns the length of each word, which is used for sorting.

4fill in blank

hard

Fill both blanks to create a dictionary of words and their lengths, including only words longer than 3 characters.

Python

word_lengths = {word: [1] for word in words if [2] > 3}

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

Alen(word)

Bword

Attempts:

💡 Hint

Common Mistakes

Using the word itself instead of its length for the dictionary value.

Checking the word string directly instead of its length in the condition.

The dictionary comprehension maps each word to its length using len(word). The condition filters words with length greater than 3.

5fill in blank

hard

Fill all three blanks to create a dictionary with uppercase words as keys, their original words as values, including only words longer than 4 characters.

Python

result = [1]: [2] for word in words if [3] > 4

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

Aword.upper()

Bword

Clen(word)

Dword.lower()

💡 Hint

Common Mistakes

Using word.lower() instead of uppercase for keys.

Using the length of the word as the value instead of the word itself.

Checking the word string directly instead of its length in the condition.

The dictionary comprehension uses the uppercase word as the key (word.upper()), the original word as the value, and filters words longer than 4 characters using len(word) > 4.
