As someone who has spent over a decade in the programming world, I’ve learned that automating repetitive tasks can save a significant amount of time and effort.
Python, with its simple syntax and powerful libraries, is one of the best programming languages for creating automation scripts. Whether you’re a programmer or someone looking to make daily tasks easier, Python has tools that can help you.
In this article, I’ll share 21 Python scripts that I’ve used to automate various tasks. These scripts are perfect for anyone who wants to save time and improve efficiency in their work routine.
1. Renaming Files in Bulk
Renaming files one by one can be a time-consuming task, but with Python, you can easily automate this by using the os module.
Here’s a simple script that renames multiple files in a folder based on a given pattern:
import os def bulk_rename(folder_path, old_name_part, new_name_part): for filename in os.listdir(folder_path): if old_name_part in filename: new_filename = filename.replace(old_name_part, new_name_part) os.rename(os.path.join(folder_path, filename), os.path.join(folder_path, new_filename)) print(f"Renamed {filename} to {new_filename}") folder = '/path/to/your/folder
' bulk_rename(folder, 'old_part
', 'new_part
')
This script searches for files containing old_name_part
in their names and replaces it with new_name_part
.
2. Backing Up Files Automatically
We all know how important it is to back up files regularly, and this task can be easily automated using Python’s shutil
module.
This script will copy all files from one directory to another for backup purposes:
import shutil import os def backup_files(src_dir, dest_dir): if not os.path.exists(dest_dir): os.makedirs(dest_dir) for file in os.listdir(src_dir): full_file_name = os.path.join(src_dir, file) if os.path.isfile(full_file_name): shutil.copy(full_file_name, dest_dir) print(f"Backed up {file} to {dest_dir}") source = '/path/to/source/directory
' destination = '/path/to/destination/directory
' backup_files(source, destination)
You can schedule this script to run daily using task-scheduling tools like cron (Linux) or Task Scheduler (Windows).
3. Downloading Files from the Internet
If you frequently download files from the internet, then you can automate this task using aiohttp
library.
Here’s a simple script to download files from URLs:
import aiohttp import asyncio import aiofiles async def download_file(url, filename): async with aiohttp.ClientSession() as session: async with session.get(url) as response: async with aiofiles.open(filename, 'wb') as file: await file.write(await response.read()) print(f"Downloaded {filename}") urls = { 'https://example.com/file1.zip': 'file1.zip', 'https://example.com/file2.zip': 'file2.zip' } async def download_all(): tasks = [download_file(url, filename) for url, filename in urls.items()] await asyncio.gather(*tasks) asyncio.run(download_all())
This script downloads the file from the specified URL and saves it to your specified folder.
4. Automating Email Reports
If you’re required to send email reports regularly, you can automate it using smtplib
library, which allows you to send emails from a Gmail account easily:
import smtplib from email.mime.text import MIMEText from email.mime.multipart import MIMEMultipart def send_email(subject, body, to_email): sender_email = '[email protected]' sender_password = 'yourpassword' receiver_email = to_email msg = MIMEMultipart() msg['From'] = sender_email msg['To'] = receiver_email msg['Subject'] = subject msg.attach(MIMEText(body, 'plain')) try: server = smtplib.SMTP('smtp.gmail.com', 587) server.starttls() server.login(sender_email, sender_password) server.sendmail(sender_email, receiver_email, msg.as_string()) server.quit() print("Email sent successfully!") except Exception as e: print(f"Failed to send email: {e}") subject = 'Monthly Report' body = 'Here is the monthly report.' send_email(subject, body, '[email protected]')
This script will send a simple email with a subject and body to a specified recipient. Make sure to enable less secure apps in Gmail if you use this method.
5. Task Scheduler (Task Automation)
Scheduling tasks can be done easily using the schedule
library, which allows you to automate tasks like sending an email or running a backup script at specific times:
import schedule import time def job(): print("Running scheduled task!") # Schedule the task to run every day at 10:00 AM schedule.every().day.at("10:00").do(job) while True: schedule.run_pending() time.sleep(1)
This script will keep running and trigger tasks at the specified time, in this case, 10:00 AM every day.
6. Web Scraping for Data Collection
Using aiohttp
for asynchronous HTTP requests instead of the synchronous requests
library can make web scraping more efficient.
This example retrieves multiple pages in parallel.
import aiohttp import asyncio from bs4 import BeautifulSoup async def fetch(session, url): async with session.get(url) as response: return await response.text() async def scrape(urls): async with aiohttp.ClientSession() as session: tasks = [fetch(session, url) for url in urls] html_pages = await asyncio.gather(*tasks) for html in html_pages: soup = BeautifulSoup(html, 'html.parser') print(soup.title.string) urls = ['https://example.com/page1
', 'https://example.com/page2
'] asyncio.run(scrape(urls))
7. Automating Social Media Posts
If you manage social media accounts, then you can automate posting by using the libraries like Tweepy
(for Twitter) and Instagram-API
(for Instagram) allow you to post automatically.
Below is an example using the Tweepy
library to post a tweet:
import tweepy def tweet(message): consumer_key = 'your_consumer_key' consumer_secret = 'your_consumer_secret' access_token = 'your_access_token' access_token_secret = 'your_access_token_secret' auth = tweepy.OAuthHandler(consumer_key, consumer_secret) auth.set_access_token(access_token, access_token_secret) api = tweepy.API(auth) api.update_status(message) print("Tweet sent successfully!") tweet("Hello, world!")
This script posts a tweet with the message “Hello, world!
” to your Twitter account.
8. Automating Invoice Generation
If you generate invoices regularly, then you can automate it using libraries like Fpdf
, which will create PDF invoices:
from fpdf import FPDF def create_invoice(client_name, amount): pdf = FPDF() pdf.add_page() pdf.set_font("Arial", size=12) pdf.cell(200, 10, txt="Invoice", ln=True, align='C') pdf.cell(200, 10, txt=f"Client: {client_name}", ln=True, align='L') pdf.cell(200, 10, txt=f"Amount: ${amount}", ln=True, align='L') pdf.output(f"{client_name}_invoice.pdf") print(f"Invoice for {client_name} created successfully!") create_invoice('John Doe', 500)
This script creates a simple invoice and saves it as a PDF.
9. Monitoring Website Uptime
Python can be used to automate monitoring of website uptime using the requests
library, that can periodically check if a website is online or not:
import requests
import time
def check_website(url):
try:
response = requests.get(url)
if response.status_code == 200:
print(f"Website {url} is up!")
else:
print(f"Website {url} returned a status code {response.status_code}")
except requests.exceptions.RequestException as e:
print(f"Error checking website {url}: {e}")
url = 'https://example.com
' while True: check_website(url) time.sleep(3600) # Check every hour
This script checks if the website is online and prints the status code.
10. Auto-Reply to Emails
If you often receive emails and want to set up an auto-reply, then use the imaplib
and smtplib
libraries to automatically reply to emails:
import imaplib import smtplib from email.mime.text import MIMEText def auto_reply(): # Connect to email server mail = imaplib.IMAP4_SSL("imap.gmail.com") mail.login('[email protected]', 'yourpassword') mail.select('inbox') # Search for unread emails status, emails = mail.search(None, 'UNSEEN') if status == "OK": for email_id in emails[0].split(): status, email_data = mail.fetch(email_id, '(RFC822)') email_msg = email_data[0][1].decode('utf-8') # Send auto-reply send_email("Auto-reply", "Thank you for your email. I'll get back to you soon.", '[email protected]') def send_email(subject, body, to_email): sender_email = '[email protected]' sender_password = 'yourpassword' receiver_email = to_email msg = MIMEText(body) msg['From'] = sender_email msg['To'] = receiver_email msg['Subject'] = subject with smtplib.SMTP_SSL('smtp.gmail.com', 465) as server: server.login(sender_email, sender_password) server.sendmail(sender_email, receiver_email, msg.as_string()) auto_reply()
This script automatically replies to unread emails with a predefined message.
11. File Cleanup
Python provides an effective way to automate file cleanup, particularly for deleting or moving old files to maintain organized directories.
Below is a simple script that deletes files older than a specified number of days using the os
and time
modules.
import aiofiles import os import asyncio import time async def clean_up(folder_path, days_old): now = time.time() cutoff_time = now - (days_old * 86400) for filename in os.listdir(folder_path): file_path = os.path.join(folder_path, filename) if os.path.getmtime(file_path) < cutoff_time: await aiofiles.os.remove(file_path) print(f"Deleted {filename}") folder = '/path/to/your/folder' asyncio.run(clean_up(folder, 30))
12. Generate Passwords Automatically
Creating strong, unique passwords is essential for security, and Python can help automate this process using the random
module.
Below is a simple script that generates random passwords of a specified length, incorporating letters, digits, and special characters to enhance security.
import random import asyncio import string async def generate_password(length=12): characters = string.ascii_letters + string.digits + string.punctuation password = ''.join(random.choice(characters) for _ in range(length)) return password async def generate_multiple_passwords(n, length=12): tasks = [generate_password(length) for _ in range(n)] passwords = await asyncio.gather(*tasks) print(passwords) asyncio.run(generate_multiple_passwords(5))
13. Task Tracker/Reminder
Creating a task tracker or reminder system in Python can be accomplished using the datetime
and asyncio
modules.
import asyncio from datetime import datetime async def task_reminder(task_name, interval): while True: print(f"Reminder: {task_name} - {datetime.now()}") await asyncio.sleep(interval) async def main(): await asyncio.gather( task_reminder("Drink Water", 7200), # Remind every 2 hours task_reminder("Take a Break", 3600) # Remind every 1 hour ) asyncio.run(main())
This script sends a reminder about the task at a scheduled time.
14. Auto-Generate Daily Reports
Automate daily reports by using Python to collect data and format it into a report:
import datetime import aiofiles import asyncio async def generate_report(data): today = datetime.date.today() filename = f"daily_report_{today}.txt" async with aiofiles.open(filename, 'w') as file: await file.write(f"Report for {today}\n") await file.write("\n".join(data)) print(f"Report generated: {filename}") data = ["Task 1: Completed", "Task 2: Pending", "Task 3: Completed"] asyncio.run(generate_report(data))
15. Monitor System Resources
If you’re a system administrator, you can use Python to monitor your system’s resources like CPU and memory usage, with the help of psutil
library.
import psutil def monitor_resources(): cpu_usage = psutil.cpu_percent(interval=1) memory_usage = psutil.virtual_memory().percent print(f"CPU Usage: {cpu_usage}%") print(f"Memory Usage: {memory_usage}%") monitor_resources()
16. Batch Image Resizing
If you need to resize images in bulk, Python makes it easy with the Pillow
library.
from PIL import Image import os import asyncio from concurrent.futures import ProcessPoolExecutor def resize_image(filename, width, height): img = Image.open(filename) img = img.resize((width, height)) img.save(f"resized_{filename}") return f"Resized {filename}" async def resize_images(folder_path, width, height): with ProcessPoolExecutor() as executor: loop = asyncio.get_event_loop() tasks = [] for filename in os.listdir(folder_path): if filename.endswith('.jpg'): tasks.append(loop.run_in_executor( executor, resize_image, os.path.join(folder_path, filename), width, height)) results = await asyncio.gather(*tasks) print(results) folder = '/path/to/your/images' asyncio.run(resize_images(folder, 800, 600))
This script resizes all .jpg
images in a folder to the specified dimensions.
17. Automating Data Backup to Cloud
Automating backups to cloud services like Google Drive is made possible with Python using libraries such as pydrive
.
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
def backup_to_google_drive(file_path):
gauth = GoogleAuth()
gauth.LocalWebserverAuth()
drive = GoogleDrive(gauth)
file = drive.CreateFile({'title': 'backup_file.txt'})
file.Upload()
print("Backup uploaded successfully!")
file = '/path/to/your/file.txt
' backup_to_google_drive(file)
18. Creating Daily Reminders
Setting daily reminders is easy with the time
module, which will remind you to drink water every 2 hours:
import time def water_reminder(): while True: print("Time to drink water!") time.sleep(7200) # Remind every 2 hours water_reminder()
19. Automating Data Entry to Excel
If you frequently enter data into Excel, Python can help automate this task with the openpyxl
library:
from openpyxl import Workbook def create_excel(data): wb = Workbook() ws = wb.active for row in data: ws.append(row) wb.save('data.xlsx') print("Excel file created successfully!") data = [ ["Name", "Age", "City"], ["John", 30, "New York"], ["Anna", 25, "London"], ] create_excel(data)
20. Automating Data Cleaning
If you work with large datasets, Python can automate data-cleaning tasks, which will remove empty rows from a CSV file:
import csv
def clean_csv(file_path):
with open(file_path, 'r') as infile:
reader = csv.reader(infile)
rows = [row for row in reader if any(row)]
with open(file_path, 'w', newline='') as outfile:
writer = csv.writer(outfile)
writer.writerows(rows)
print("Empty rows removed from CSV")
file = '/path/to/your/data.csv
' clean_csv(file)
21. Text Extract from Images
Python can be used to extract text from images using the pytesseract
library, which can be useful when you need to digitize printed content or extract text from scanned documents.
from PIL import Image import pytesseract def extract_text_from_image(image_path): # Open the image file img = Image.open(image_path) # Use pytesseract to extract text text = pytesseract.image_to_string(img) return text image_path = 'path_to_your_image.jpg' extracted_text = extract_text_from_image(image_path) print("Extracted Text:\n", extracted_text)
Conclusion
These are just a few examples of what Python can do to automate your daily tasks. With its simple syntax and powerful libraries, Python can handle almost any task you throw at it.
Whether you’re managing files, sending emails, or generating reports, Python can save you time and improve your productivity. So, get started with Python automation today, and let it handle your daily chores!
Loved It!!
Pathetic. All of this can be done using PowerShell or CMD. This is a perfect example of how, when your tool is a hammer, driving in screws can still be done with a hammer.
It’s been long since I read a blog that I liked. This is a good blog worth sharing.
Keep it up!
I want to execute your activity to learn a new technique in Python. I love Python.
@Shane,
That’s great to hear! Enjoy learning the new technique in Python!
Very informative article on Python…
Very nice and powerful blog!
The step-by-step approach makes each Python automation example clear and easy to follow…
Please avoid providing outdated programming examples. All your code uses synchronous and blocking calls, which is inefficient for modern, asynchronous Python applications. Using the
requests
library for network calls, for example, is no longer ideal—consider usingaiohttp
for asynchronous HTTP requests. Similarly, for file operations,aiofiles
is a more suitable choice, as it avoids blocking the event loop.It’s important to become familiar with
asyncio
to handle asynchronous programming in Python. And with Python 3.13 potentially removing the GIL (Global Interpreter Lock), learning about threading and concurrency will be even more essential.In summary, please update your examples to reflect current best practices and to make use of asynchronous libraries where appropriate.
@Syle,
Thank you for your feedback! I appreciate you highlighting the importance of using asynchronous libraries. I’ve updated the examples in the article to incorporate
aiohttp
for HTTP requests andaiofiles
for file operations, following modern asynchronous best practices.Additionally, I included a section on using
asyncio
to handle concurrency, which aligns with the upcoming changes in Python 3.13 regarding the GIL.Your input has been invaluable in improving the content. Thanks again for helping me make it better!
Why your answers seems very similar to chatgpt? Maybe because they are!?!
@Bostjan,
Thanks for your comment!
My goal is to provide helpful and clear answers, and yes, I use AI tools like ChatGPT to assist in generating accurate and informative content. However, I make sure to personalize and refine the information to suit your needs. I hope you find the Python scripts useful for your daily tasks!
As a beginner, this was eye-opening! I didn’t know aiohttp or aiofiles were better for async tasks, or about Python 3.13 possibly removing the GIL. This makes me excited to explore modern Python practices and improve my understanding of concurrency!
