Python Automation Projects

# Python Automation Projects

Welcome to Chapter 27! Automation is Python's superpower. In this chapter, you'll build real projects that automate repetitive tasks — saving hours of manual work.

---

1. Learning Objectives #

• Automate file and folder management.

• Send automated emails.

• Schedule tasks programmatically.

• Work with PDFs and Excel files.

• Build practical automation scripts.

---

2. Project 1: Automatic File Organizer #

Organizes files in a folder by their extensions:

```python id="py27project1" import os import shutil from pathlib import Path

def organizefiles(directory): """Organize files into folders by extension""" extensionmap = { "Images": [".jpg", ".jpeg", ".png", ".gif", ".svg", ".bmp", ".webp"], "Documents": [".pdf", ".doc", ".docx", ".txt", ".xlsx", ".csv", ".pptx"], "Videos": [".mp4", ".avi", ".mkv", ".mov", ".wmv"], "Audio": [".mp3", ".wav", ".flac", ".aac", ".ogg"], "Archives": [".zip", ".rar", ".7z", ".tar", ".gz"], "Code": [".py", ".js", ".html", ".css", ".java", ".cpp"], } dirpath = Path(directory) movedcount = 0 for file in dirpath.iterdir(): if file.isfile(): ext = file.suffix.lower() foldername = "Others" for category, extensions in extensionmap.items(): if ext in extensions: foldername = category break targetdir = dirpath / foldername targetdir.mkdir(existok=True) shutil.move(str(file), str(targetdir / file.name)) movedcount += 1 print(f" 📁 {file.name} → {foldername}/") print(f"\n ✅ Organized {movedcount} files!")

# Usage: organizefiles("/path/to/messy/folder") print("=" * 40) print(" 📁 FILE ORGANIZER") print("=" * 40) folder = input(" Enter folder path: ") if os.path.isdir(folder): organize_files(folder) else: print(" ❌ Invalid directory!")

---

## 3. Project 2: Email Sender

python id="py27project2" import smtplib from email.mime.text import MIMEText from email.mime.multipart import MIMEMultipart

def sendemail(sender, password, recipient, subject, body): """Send an email using SMTP""" msg = MIMEMultipart() msg["From"] = sender msg["To"] = recipient msg["Subject"] = subject msg.attach(MIMEText(body, "html")) try: # Gmail SMTP server with smtplib.SMTP("smtp.gmail.com", 587) as server: server.starttls() # Enable encryption server.login(sender, password) server.sendmessage(msg) print(" ✅ Email sent successfully!") except Exception as e: print(f" ❌ Error: {e}")

# Usage (use App Password for Gmail, not regular password) # sendemail( # "youremail@gmail.com", # "yourapp_password", # "recipient@example.com", # "Hello from Python!", # "<h1>Automated Email</h1><p>Sent with Python!</p>" # )

---

## 4. Project 3: Bulk File Renamer

python id="py27project3" import os from pathlib import Path

def bulkrename(directory, prefix="file", start=1): """Rename all files with a sequential prefix""" dirpath = Path(directory) files = sorted([f for f in dirpath.iterdir() if f.isfile()]) print(f"\n Renaming {len(files)} files...") for i, file in enumerate(files, start): newname = f"{prefix}{i:03d}{file.suffix}" newpath = dirpath / newname file.rename(newpath) print(f" {file.name} → {newname}") print(f"\n ✅ Renamed {len(files)} files!")

# Usage: bulk_rename("/path/to/photos", prefix="vacation", start=1)

---

## 5. Project 4: System Monitor

python id="py27project4" import os import platform import shutil from datetime import datetime

def systemreport(): """Generate a system information report""" print("=" * 45) print(" 💻 SYSTEM MONITOR REPORT") print("=" * 45) # System info print(f"\n {'System':<15}: {platform.system()} {platform.release()}") print(f" {'Machine':<15}: {platform.machine()}") print(f" {'Processor':<15}: {platform.processor()[:30]}") print(f" {'Python':<15}: {platform.pythonversion()}") # Disk usage total, used, free = shutil.diskusage("/") print(f"\n Disk Usage:") print(f" {'Total':<15}: {total // (230)} GB") print(f" {'Used':<15}: {used // (230)} GB") print(f" {'Free':<15}: {free // (2**30)} GB") print(f" {'Usage':<15}: {used/total*100:.1f}%") # Report time print(f"\n Generated: {datetime.now().strftime('%Y-%m-%d %H:%M:%S')}") print("=" * 45)

system_report()

---

## 6. Project 5: Password Generator

python id="py27project5" import random import string

def generatepassword(length=16, uppercase=True, digits=True, special=True): """Generate a secure random password""" chars = string.asciilowercase if uppercase: chars += string.asciiuppercase if digits: chars += string.digits if special: chars += "!@#$%^&*" password = ''.join(random.choice(chars) for in range(length)) # Ensure at least one of each required type required = [random.choice(string.asciilowercase)] if uppercase: required.append(random.choice(string.asciiuppercase)) if digits: required.append(random.choice(string.digits)) if special: required.append(random.choice("!@#$%^&*")) pwdlist = list(password[:length - len(required)] + ''.join(required)) random.shuffle(pwdlist) return ''.join(pwdlist)

print("=" * 40) print(" 🔐 PASSWORD GENERATOR") print("=" * 40)

for i in range(5): pwd = generate_password(16) print(f" {i+1}. {pwd}")

---

## 7. Task Scheduling

python id="py27ex1" import time from datetime import datetime

def runscheduler(task, intervalseconds, maxruns=5): """Simple task scheduler""" run = 0 while run < maxruns: run += 1 timestamp = datetime.now().strftime("%H:%M:%S") print(f" [{timestamp}] Run {run}: ", end="") task() time.sleep(intervalseconds)

# Example task def checkstatus(): print("System status: OK ✅")

# Run every 3 seconds, 5 times # runscheduler(checkstatus, 3, 5) ``

Q3: Path.mkdir(existok=True) does: A) Always creates B) Creates if doesn't exist C) Deletes and creates D) Error Answer: B

Q4: os.listdir() returns: A) File sizes B) File names C) File paths D) File types Answer: B

Q6: pathlib.Path is: A) Deprecated B) Modern path handling C) Only for Linux D) Only for Windows Answer: B

Q7: shutil.diskusage() returns: A) CPU usage B) Disk total/used/free C) Memory usage D) Network usage Answer: B

Q8: string.asciiletters contains: A) Digits B) Lowercase only C) Letters a-z + A-Z D) Special chars Answer: C

Q9: time.sleep(5) pauses for: A) 5 milliseconds B) 5 seconds C) 5 minutes D) 5 hours Answer: B

1. 2. How to schedule Python scripts? schedule library, cron (Linux), Task Scheduler (Windows), APScheduler.

• Use pathlib and shutil for file management.

• Use smtplib for sending emails.

• Use os and platform` for system information.

• Always handle errors and edge cases in automation scripts.
