summary = ” “.join([sent.text for sent in doc.sents][:3])

This line extracts the first three sentences from the document and creates a summary. Here’s the breakdown:

• for sent in doc.sents: Iterates over each sentence in the document doc.
• sent.text: Gets the text of the sentence.
• [:3]: This slices the list to get only the first three sentences.
• " ".join(...): Joins the list of sentence texts into a single string, with each sentence separated by a space.

So, this code takes the first three sentences from the document and combines them into a short summary.

Summary of Both Lines:

• The first line extracts important words (keywords) from the document, filtering out non-alphabetical tokens and stop words.
• The second line creates a summary by extracting and joining the first three sentences of the document.
