Python BeautifulSoup: Extract Paragraphs by Title with Error Fix

The code is missing an import statement for the `requests` library, which is required to retrieve the HTML content. Here's the updated code with the necessary import statement: \n\npython\nimport requests\nfrom bs4 import BeautifulSoup\n\ndef retrieve_paragraphs_by_title(url):\n response = requests.get(url)\n html = response.content\n soup = BeautifulSoup(html, 'html.parser')\n\n paragraphs = []\n for title in soup.find_all(['h1', 'h2', 'h3', 'h4', 'h5', 'h6']):\n paragraph_text = ''\n for sibling in title.find_next_siblings():\n if sibling.name.startswith('h'):\n break\n elif sibling.name == 'p':\n paragraph_text += sibling.get_text()\n paragraphs.append((title.get_text(), paragraph_text.strip()))\n\n return paragraphs\n\n\nThis code uses the `requests.get()` function to retrieve the HTML content from the specified URL. It then passes the content to BeautifulSoup for parsing. The rest of the code remains unchanged.
