BetterClaw

What this is

BetterClaw is a Python library used for web scraping and data extraction. It provides an efficient and easy-to-use way to extract data from websites. BetterClaw is designed to handle common web scraping tasks, such as handling different types of content, rotating user agents, and avoiding anti-scraping measures.

Installation

pip install betterclaw

Key concepts

The most important APIs and patterns in BetterClaw include:

• betterclaw.Client: The main entry point for making HTTP requests and extracting data.
• betterclaw.Parser: Used to parse HTML and XML content.
• betterclaw.RotationPolicy: Defines how user agents are rotated to avoid anti-scraping measures.

Example:

from betterclaw import Client

client = Client()
response = client.get("https://www.example.com")
print(response.text)

Correct usage patterns

When using BetterClaw, make sure to handle exceptions and errors properly:

from betterclaw import Client
from betterclaw.exceptions import RequestException

client = Client()
try:
    response = client.get("https://www.example.com")
    print(response.text)
except RequestException as e:
    print(f"An error occurred: {e}")

Common mistakes to avoid

• Not handling exceptions and errors properly
• Not rotating user agents, leading to IP blocks
• Not checking the library's documentation for updates and changes

File and folder conventions

• Configuration files should be named betterclaw.cfg and placed in the root directory of the project.
• Log files should be named betterclaw.log and placed in the logs directory.
• User-defined parsers and rotation policies should be placed in separate modules and imported as needed.
