## GeneralScraper.py

Our beginner-friendly scraper designed for individuals new to web data extraction. It leverages popular libraries such as `requests`, `BeautifulSoup`, and `urllib` to deliver essential functionalities while keeping things simple.

**Features:**

- User-friendly interface guiding users through each step
- Four primary data extraction methods:
  - Extract post contents (`<p>` tags)
  - Collect internal and external links (`<a>` tags with `href` attributes)
  - Aggregate all visible text contents
  - Perform query-based searches across the entire website

**Getting Started:**

1. Make sure you have Python installed.
2. Install necessary packages:

   ```

**Required Packages:**

2. Choose a data extraction method based on the provided options:
   * 0: Extract post contents (typically `<p>` tags)
   * 1: Gather internal & external links (`<a>` tags with `href` attribute)
   * 2: Collect all visible text contents
   * 3: Conduct a query-based search across the whole website; enter the desired query when requested
