3.Required Libraries: Install the necessary Python libraries:

pip install requests BeautifulSoup4

Building a Basic Instagram Scraper

For this tutorial, we'll scrape public posts from a given Instagram profile:

1.Import Necessary Libraries:

1Pythonimport requests
2from bs4 import BeautifulSoup

2.Define the URL and Send a Request:

1Pythonprofile = 'instagram_username' # Replace with the desired Instagram username url = f'https://www.instagram.com/{profile}/' response = requests.get(url)

3.Parse the Response:

1Pythonsoup = BeautifulSoup(response.text, 'html.parser')

4.Extract Data:

1Python# Extracting the profile's bio
2bio = soup.find('div', class_='-vDIg').span.text
3
4# Extracting recent post captions
5scripts = soup.find_all('script', type='text/javascript')
6shared_data_script = [script for script in scripts if 'window._sharedData' in script.text][0]
7shared_data = json.loads(shared_data_script.text.split('window._sharedData = ')[1].rstrip(';'))
8posts = shared_data['entry_data']['ProfilePage'][0]['graphql']['user']['edge_owner_to_timeline_media']['edges']
9
10captions = [post['node']['edge_media_to_caption']['edges'][0]['node']['text'] for post in posts]

5.Display Extracted Data:

1Pythonprint(f"Bio of {profile}: {bio}") print("\nRecent Post Captions:") for caption in captions: print(caption)
