Automating File Management Python's os and shutil modules help you rename, move, or delete files automatically. Example: Rename All .txt Files in a Folder import os

folder_path = '/path/to/your/folder'

for filename in os.listdir(folder_path):
if filename.endswith('.txt'):
new_name = 'renamed_' + filename
os.rename(
os.path.join(folder_path, filename),
os.path.join(folder_path, new_name)
)

Automating Excel Reports with openpyxl Python can read and write Excel files easily using openpyxl. Example: Update Prices in Excel Sheet python CopyEdit from openpyxl import load_workbook

wb = load_workbook('sales_data.xlsx')
sheet = wb.active

for row in sheet.iter_rows(min_row=2, max_col=2):

new_price = price * 1.1 # 10% increase
row[1].value = new_price

wb.save('sales_data_updated.xlsx')
Useful for: Small business owners, accountants, data analysts.

Automate Sending Emails with smtplib Python can send emails using Gmail, Outlook, or other SMTP servers. Example: Send a Custom Email python CopyEdit import smtplib from email.mime.text import MIMEText

sender = 'you@example.com'
receiver = 'client@example.com'
password = 'your_app_password'

message = MIMEText('Hello, this is an automated email!')
message['Subject'] = 'Automated Update'
message['From'] = sender
message['To'] = receiver

with smtplib.SMTP_SSL('smtp.gmail.com', 465) as server:
server.login(sender, password)
server.send_message(message)
Tip: Use an App Password for Gmail (2FA must be enabled).

Automating Web Browsing with Selenium Use Selenium to automate web form submissions, scraping, and testing. Example: Auto-Login to a Website python CopyEdit from selenium import webdriver from selenium.webdriver.common.by import By
