1

Create a list of sentences from the article

Create a list called sentences with these exact sentences as strings: 'Artificial intelligence is changing the world.', 'It helps in many fields like healthcare and education.', 'However, it also raises ethical questions.', 'People need to understand both benefits and risks.', 'Learning about AI is important for everyone.'

Hint

Use square brackets [] to create a list and put each sentence inside quotes separated by commas.

2

Set a threshold for sentence importance

Create a variable called importance_threshold and set it to the number 2. This will help decide which sentences are important enough to include in the summary.

AI for Everyone

sentences = [
    'Artificial intelligence is changing the world.',
    'It helps in many fields like healthcare and education.',
    'However, it also raises ethical questions.',
    'People need to understand both benefits and risks.',
    'Learning about AI is important for everyone.'
]
# Create the variable importance_threshold and set it to 2
# Your code here

Hint

Just assign the number 2 to the variable named importance_threshold.

3

Select sentences that meet the importance threshold

Create a list called important_sentences that includes sentences from sentences which contain the word 'important' or 'raises'. Use a for loop with the variable sentence to check each sentence.

sentences = [
    'Artificial intelligence is changing the world.',
    'It helps in many fields like healthcare and education.',
    'However, it also raises ethical questions.',
    'People need to understand both benefits and risks.',
    'Learning about AI is important for everyone.'
]
importance_threshold = 2
# Create the list important_sentences with sentences containing 'important' or 'raises'
# Your code here

Hint

Use a for loop to check each sentence. Use if to check if the sentence contains the words 'important' or 'raises'. Add matching sentences to important_sentences.

4

Write a short summary using the selected sentences

Create a string variable called summary by joining the sentences in important_sentences with a space ' ' between them.

sentences = [
    'Artificial intelligence is changing the world.',
    'It helps in many fields like healthcare and education.',
    'However, it also raises ethical questions.',
    'People need to understand both benefits and risks.',
    'Learning about AI is important for everyone.'
]
importance_threshold = 2
important_sentences = []
for sentence in sentences:
    if 'important' in sentence or 'raises' in sentence:
        important_sentences.append(sentence)
# Create the summary string by joining important_sentences with spaces
# Your code here

Hint

Use the join method on a space string to combine the sentences into one summary string.
