In this blog, we will explore how to automate simple daily tasks with Python, making your workflow faster and error-free.

Why Automate?

Automation saves time, reduces human error, and lets you focus on high-value tasks. With Python’s powerful libraries, automating small repetitive tasks becomes very straightforward.

Example 1: Rename Multiple Files

Suppose you have a folder with hundreds of files that you want to rename systematically. Here’s how to do it:

import os

folder_path = 'path_to_folder'

for count, filename in enumerate(os.listdir(folder_path)):
    dst = f"file_{str(count)}.jpg"  # rename logic here
    src = os.path.join(folder_path, filename)
    dst = os.path.join(folder_path, dst)

    os.rename(src, dst)

print("Files renamed successfully.")

Replace path_to_folder with your directory path. This will rename files as file_0.jpg, file_1.jpg, etc.

Example 2: Sending Emails Automatically

You can send automated emails using Python’s smtplib. Example:

import smtplib

server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()

server.login('your_email@gmail.com', 'your_password')
server.sendmail('your_email@gmail.com', 'receiver_email@gmail.com', 'This is an automated email from Python.')

server.quit()

Note: For Gmail, enable less secure app access or use app passwords for security.

Example 3: Convert Multiple Images to PDF

Convert all images in a folder into a single PDF file:

from PIL import Image
import os

folder = 'images_folder'
images = []

for file in os.listdir(folder):
    if file.endswith('.jpg') or file.endswith('.png'):
        img = Image.open(os.path.join(folder, file)).convert('RGB')
        images.append(img)

images[0].save('output.pdf', save_all=True, append_images=images[1:])
print("PDF created successfully.")

Change 'images_folder' to your folder containing images.

Final Thoughts

Python automation scripts can simplify your life. Start with simple file operations and emails, then move towards web scraping, API automation, and real-time data pipelines as your skills grow.
