BeautifulSoup Documentation

There are four main objects in BeautifulSoup:

- BeautifulSoup
- Tag
- NavigableString
- Comment

BeautifulSoup Objects

To get started, we need to import BeautifulSoup from bs4, then parse our file by passing it into the BeautifulSoup constructor.
```Python
from bs4 import BeautifulSoup

with open('filename.html') as f:
    soup = BeautifulSoup(f, 'html.parser')

```
A "soup" object can also be created by getting HTML content directly from a website using the Requests module:
```Python
import requests

response = requests.get("https://example.com")
soup = BeautifulSoup(response.content, "html.parser")

```

Creating the "soup"

Installing Beautiful Soup is easiest if you have pip or another Python installer already in place. If you don’t have pip, run through a quick tutorial on installing python modules to get it running. Once you have pip installed, run the following command in the terminal to install Beautiful Soup:
```Python
$ pip install beautifulsoup4
```
