🐍 Lesson 29: Python Automation – Automate Files, Folders, Emails & More

Welcome to Lesson 29! Today we’ll explore how Python can automate daily tasks — file management, sending emails, working with folders, and more. Automation helps you save time, remove repetitive work, and build powerful scripts for real-world usage.

💡 Quick Benefits of Python Automation

• Save hours of repetitive work
• Automate daily office tasks (files, emails, screenshots)
• Automate reports, data collection, and emails
• Build powerful bots and assistants for personal or work use
• Control your computer programmatically for streamlined workflows

🗂 1. Automating Files & Folders

📦 Create Folders Automatically

import os

os.makedirs("my_folder", exist_ok=True)
print("Folder created!")

📦 List All Files in a Directory

import os

files = os.listdir(".")
print(files)

📦 Moving & Renaming Files

import os

os.rename("old.txt", "new.txt")
print("File renamed!")

📧 2. Sending Emails with Python

Use Python’s smtplib module to send emails.

import smtplib

sender = "youremail@example.com"
password = "YOUR_PASSWORD"
receiver = "friend@example.com"

message = """Subject: Hello from Python
This email was sent using Python automation!
"""

with smtplib.SMTP("smtp.gmail.com", 587) as server:
    server.starttls()
    server.login(sender, password)
    server.sendmail(sender, receiver, message)

print("Email sent!")

Note: Gmail requires special app passwords or security settings.

📄 3. Reading Text from PDFs

pip install PyPDF2

import PyPDF2

with open("example.pdf", "rb") as file:
    reader = PyPDF2.PdfReader(file)
    text = reader.pages[0].extract_text()
    print(text)

---

🖼 4. Automating Screenshots

pip install pyautogui

import pyautogui

screenshot = pyautogui.screenshot()
screenshot.save("screenshot.png")

---

🌐 5. Automating Website Actions

Using Selenium, you can automate clicking, typing, scraping, and browsing.

pip install selenium

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://google.com")
print(driver.title)

🧠 Why Python Automation Is Powerful

• Save hours of repetitive work
• Automate office tasks
• Automate email reports
• Build bots and assistants
• Control your computer programmatically

---

🧪 Practice

1. Create a script that renames all files in a folder.
2. Write a program that takes a screenshot every 10 seconds.
3. Automate sending an email (use a test email for safety).
4. Extract text from a PDF and save it into a text file.

---

❓ Common Mistakes

• Forgetting to handle errors in file operations (e.g., missing files or permissions)
• Not setting proper security settings when sending emails (e.g., app passwords)
• Overcomplicating the script—keep automation tasks simple and efficient

❓ Frequently Asked Questions (FAQ)

1. How do I use automation for file management?

Automation can be used to organize files, rename, move, or delete them based on specific conditions or tasks.

2. Can I automate sending emails with attachments?

Yes! You can use Python’s smtplib along with email.mime to send emails with attachments. It is great for automating reports or newsletters.

3. How can I automate web actions?

You can use the selenium library to control a web browser, fill out forms, scrape data, and more.
