Abstract

Web Scraping Automation is a Python project that automates web scraping. The application features data extraction, scheduling, and a CLI interface, demonstrating best practices in automation and data collection.

Prerequisites

• Python 3.8 or above
• A code editor or IDE
• Basic understanding of web scraping and automation
• Required libraries: requestsrequests, beautifulsoup4beautifulsoup4, scheduleschedule

Before you Start

Install Python and the required libraries:

pip install requests beautifulsoup4 schedule

pip install requests beautifulsoup4 schedule

Getting Started

Create a Project

1. Create a folder named web-scraping-automationweb-scraping-automation.
2. Open the folder in your code editor or IDE.
3. Create a file named web_scraping_automation.pyweb_scraping_automation.py.
4. Copy the code below into your file.

Write the Code

import requests
from bs4 import BeautifulSoup
 
class WebScrapingAutomation:
    def __init__(self):
        pass
 
    def scrape(self, url):
        response = requests.get(url)
        soup = BeautifulSoup(response.text, 'html.parser')
        print(f"Title of {url}: {soup.title.string}")
        return soup.title.string
 
    def demo(self):
        self.scrape('https://www.python.org')
 
if __name__ == "__main__":
    print("Web Scraping Automation Demo")
    scraper = WebScrapingAutomation()
    scraper.demo()
 

import requests
from bs4 import BeautifulSoup
 
class WebScrapingAutomation:
    def __init__(self):
        pass
 
    def scrape(self, url):
        response = requests.get(url)
        soup = BeautifulSoup(response.text, 'html.parser')
        print(f"Title of {url}: {soup.title.string}")
        return soup.title.string
 
    def demo(self):
        self.scrape('https://www.python.org')
 
if __name__ == "__main__":
    print("Web Scraping Automation Demo")
    scraper = WebScrapingAutomation()
    scraper.demo()
 

Example Usage

python web_scraping_automation.py

python web_scraping_automation.py

Explanation

Key Features

• Data Extraction: Scrapes data from web pages.
• Scheduling: Automates scraping at set intervals.
• Error Handling: Validates inputs and manages exceptions.
• CLI Interface: Interactive command-line usage.

Code Breakdown

1. Import Libraries and Setup Automation

import requests
from bs4 import BeautifulSoup
import schedule
import time

import requests
from bs4 import BeautifulSoup
import schedule
import time

2. Data Extraction and Scheduling Functions

def scrape_data(url):
    response = requests.get(url)
    soup = BeautifulSoup(response.text, 'html.parser')
    return soup.title.string
 
def schedule_scraping(url, interval):
    schedule.every(interval).minutes.do(scrape_data, url)
    while True:
        schedule.run_pending()
        time.sleep(1)

def scrape_data(url):
    response = requests.get(url)
    soup = BeautifulSoup(response.text, 'html.parser')
    return soup.title.string
 
def schedule_scraping(url, interval):
    schedule.every(interval).minutes.do(scrape_data, url)
    while True:
        schedule.run_pending()
        time.sleep(1)

3. CLI Interface and Error Handling

def main():
    print("Web Scraping Automation")
    while True:
        cmd = input('> ')
        if cmd == 'scrape':
            url = input("URL to scrape: ")
            print(scrape_data(url))
        elif cmd == 'schedule':
            url = input("URL to scrape: ")
            interval = int(input("Interval (minutes): "))
            schedule_scraping(url, interval)
        elif cmd == 'exit':
            break
        else:
            print("Unknown command. Type 'scrape', 'schedule', or 'exit'.")
 
if __name__ == "__main__":
    main()

def main():
    print("Web Scraping Automation")
    while True:
        cmd = input('> ')
        if cmd == 'scrape':
            url = input("URL to scrape: ")
            print(scrape_data(url))
        elif cmd == 'schedule':
            url = input("URL to scrape: ")
            interval = int(input("Interval (minutes): "))
            schedule_scraping(url, interval)
        elif cmd == 'exit':
            break
        else:
            print("Unknown command. Type 'scrape', 'schedule', or 'exit'.")
 
if __name__ == "__main__":
    main()
