def automate_file_management(directory_path):
    # List all files in the directory
    files = os.listdir(directory_path)

    # Perform automated operations on files
    for file in files:
        # Your custom logic here
        pass

Web Scraping Automation

Web scraping is a common task for extracting valuable information from websites. Python excels in this domain with its rich ecosystem of libraries, and the automation script for web scraping is no exception. The BeautifulSoup library, coupled with requests, empowers developers to scrape and parse HTML effortlessly.

The automation script allows you to specify the target website, define the data you want to extract, and even schedule periodic scrapes. Whether you’re gathering market data, monitoring competitors, or extracting research insights, Python’s web scraping automation script is a valuable addition to your toolkit.

    # Connect to the SQLite database
    conn = sqlite3.connect(database_path)
    cursor = conn.cursor()

    # Execute SQL queries
    cursor.execute("SELECT * FROM table_name")

    # Process the results
    results = cursor.fetchall()
    # Your custom logic here

    # Close the connection
    conn.close()

Python’s network automation script empowers developers to streamline tasks related to network devices, configuration management, and monitoring. The paramiko library, for instance, facilitates SSH connectivity, allowing for secure communication with devices.

This automation script enables developers to automate routine network tasks, such as configuring routers, switches, and firewalls. Additionally, it supports the retrieval of network statistics and status information, making it an invaluable tool for network administrators and developers alike.

import paramiko

def network_automation(hostname, username, password):
    # Create an SSH client
    ssh = paramiko.SSHClient()

    # Connect to the device
    ssh.connect(hostname, username=username, password=password)

    # Execute commands on the device
    stdin, stdout, stderr = ssh.exec_command('show interfaces')

    # Process the command output
    output = stdout.read()
    # Your custom logic here

    # Close the SSH connection
    ssh.close()

Automate Email Communication?

Python’s automation script for email communication simplifies the process of sending, receiving, and managing emails. The smtplib library, along with email.message, allows developers to send emails programmatically.

This script is particularly useful for applications requiring automated email notifications, newsletters, or batch email processing. By integrating Python’s email automation script, developers can enhance communication workflows and keep users informed.

import smtplib
from email.mime.text import MIMEText

def email_automation(sender_email, recipient_email, subject, message):
    # Create the MIME message
    mime_message = MIMEText(message)
    mime_message['Subject'] = subject
    mime_message['From'] = sender_email
    mime_message['To'] = recipient_email

    # Connect to the SMTP server
    with smtplib.SMTP('smtp.example.com', 587) as server:
        # Login to the email server
        server.login('your_username', 'your_password')
