Contextual compression in Prompt Engineering / GenAI - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a simple function that compresses text by removing vowels.

Prompt Engineering / GenAI

def compress_text(text):
    vowels = 'aeiouAEIOU'
    return ''.join(char for char in text if [1])

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

Achar.isdigit()

Bchar not in vowels

Cchar in vowels

Dchar == ' '

💡 Hint

Common Mistakes

Using 'char in vowels' will keep vowels instead of removing them.

The function removes vowels by keeping only characters not in the vowels string.

2fill in blank

medium

Complete the code to calculate the compression ratio of original and compressed text lengths.

Prompt Engineering / GenAI

def compression_ratio(original, compressed):
    return len(compressed) / [1]

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

Alen(original) - len(compressed)

Blen(compressed)

Clen(original) + len(compressed)

Dlen(original)

💡 Hint

Common Mistakes

Dividing by compressed length instead of original length.

The compression ratio is the length of compressed text divided by the length of original text.

3fill in blank

hard

Fix the error in the function that compresses text by replacing spaces with underscores.

Prompt Engineering / GenAI

def compress_spaces(text):
    return text.replace(' ', [1])

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

A' '

B'-'

C'_'

D''

💡 Hint

Common Mistakes

Using empty string '' removes spaces instead of replacing them.

Replacing spaces with underscores uses '_' as the replacement string.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps words to their compressed forms by removing vowels.

Prompt Engineering / GenAI

compressed_dict = {word: ''.join(char for char in word if [1]) for word in words if [2]

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

Achar not in 'aeiouAEIOU'

Bchar in 'aeiouAEIOU'

Clen(word) > 3

Dlen(word) < 3

💡 Hint

Common Mistakes

Using 'char in vowels' keeps vowels instead of removing them.

Filtering words shorter than 3 instead of longer.

The comprehension removes vowels from words longer than 3 characters.

5fill in blank

hard

Fill all three blanks to create a function that compresses text by removing vowels, replacing spaces with underscores, and calculating compression ratio.

Prompt Engineering / GenAI

def full_compress(text):
    no_vowels = ''.join(char for char in text if [1])
    replaced = no_vowels.replace(' ', [2])
    ratio = len(replaced) / [3]
    return replaced, ratio

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

Achar not in 'aeiouAEIOU'

B'_'

Clen(text)

D' '

💡 Hint

Common Mistakes

Replacing spaces with spaces instead of underscores.

Dividing by compressed length instead of original length.

The function removes vowels, replaces spaces with underscores, and calculates compression ratio by dividing compressed length by original length.
