1. File Automation

Renaming Files Automatically

import os

folder = "files"

for i, file in enumerate(os.listdir(folder)):
    new_name = f"file_{i}.txt"
    os.rename(
        os.path.join(folder, file),
        os.path.join(folder, new_name)
    )

---

2. File Creation Automation

for i in range(5):
    with open(f"file_{i}.txt", "w") as f:
        f.write("Hello Automation")

---

3. Web Automation

Using requests:

import requests

response = requests.get("https://example.com")

print(response.status_code)

---

4. Web Scraping Automation

from bs4 import BeautifulSoup
import requests

url = "https://example.com"
page = requests.get(url)

soup = BeautifulSoup(page.text, "html.parser")

print(soup.title.text)

---

5. Email Automation

import smtplib

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

server.login("your_email@gmail.com", "password")

server.sendmail(
    "from@gmail.com",
    "to@gmail.com",
    "Hello from Python Automation"
)

server.quit()

---

6. Excel Automation

Using openpyxl:

from openpyxl import Workbook

wb = Workbook()
sheet = wb.active

sheet["A1"] = "Name"
sheet["B1"] = "Score"

wb.save("data.xlsx")

---

7. System Automation

Get system info

import os

print(os.name)
print(os.getcwd())

---

8. Scheduling Automation Tasks

Using schedule:

import schedule
import time

def job():
    print("Running scheduled task")

schedule.every(5).seconds.do(job)

while True:
    schedule.run_pending()
    time.sleep(1)

---

9. Browser Automation (Selenium)

from selenium import webdriver

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

---

10. API Automation

import requests

data = {
    "name": "John"
}

response = requests.post(
    "https://example.com/api",
    json=data
)

print(response.json())

---

11. Real-World Automation Examples

Python automation is used in:

• Data entry automation
• Social media posting
• Report generation
• Email marketing
• Web scraping bots
• DevOps scripts

---

12. Advantages of Automation

• Saves time
• Reduces human error
• Increases productivity
• Works 24/7
• Scalable workflows

---

13. Common Mistakes

Hardcoding paths

folder = "/Users/name/Desktop"

Use dynamic paths instead.

---

Not handling errors

Always use try-except in automation scripts.

try:
    print("Running task")
except Exception as e:
    print(e)

---

Best Practices

• Use virtual environments
• Log automation results
• Handle exceptions properly
• Use scheduling wisely
• Keep scripts modular

---

Summary

Python automation allows developers to eliminate repetitive tasks and increase productivity. With powerful libraries like os, requests, selenium, and openpyxl, you can automate almost anything.

---

Conclusion

Python is one of the best tools for automation. Whether you're working with files, web data, emails, or system tasks, Python helps you build efficient and scalable automation solutions with minimal effort.
