Simple Automation Scripts

Automation means using code to do repeated work for you.

Instead of doing the same task by hand again and again, Python can do it automatically.

What Is Automation?

Automation is when a program completes tasks with little or no manual work.

Examples:

• Rename many files
• Move files into folders
• Create backups
• Read reports
• Save logs
• Clean old files

Why Automation Matters

Automation helps you:

• Save time
• Reduce mistakes
• Handle many files quickly
• Repeat tasks easily

Example 1: Auto Backup File

Copy one file into a backup folder.

import shutil
import os

if not os.path.exists("backup"):
    os.mkdir("backup")

shutil.copy("notes.txt", "backup/notes.txt")
print("Backup complete")

Output

Backup complete

Example 2: Rename Many Files

Rename files using a loop.

import os

files = ["a.txt", "b.txt", "c.txt"]

count = 1

for file in files:
    new_name = f"file_{count}.txt"
    print(file, "->", new_name)
    count += 1

Output

a.txt -> file_1.txt
b.txt -> file_2.txt
c.txt -> file_3.txt

(Use os.rename() in a real folder.)

Example 3: Move Text Files

Move all .txt files into a folder.

import os
import shutil

files = ["notes.txt", "photo.jpg", "tasks.txt"]

for file in files:
    if file.endswith(".txt"):
        print("Move:", file)

Output

Move: notes.txt
Move: tasks.txt

(Use shutil.move() in a real folder.)

Example 4: Read Many Files

files = ["day1.txt", "day2.txt"]

for file in files:
    print("Reading", file)

Output

Reading day1.txt
Reading day2.txt

Build an Automation Mindset

Ask:

• What task repeats often?
• Can Python do it?
• Can a loop handle many items?
• Can files be organized automatically?

Code Along

Build a report creator.

with open("report.txt", "w") as file:
    file.write("Daily Report Ready")

print("Report created")

Output

Report created

Mini Challenge

Build a file organizer.

Steps:

• Create a list:

["notes.txt", "photo.jpg", "tasks.txt", "music.mp3"]

• Use a loop
• Print only files ending with .txt
• Print message:

Move notes.txt
Move tasks.txt

Expected output:

Move notes.txt
Move tasks.txt

Real World Use Case

Companies use automation for backups, reports, email lists, file cleanup, data exports, and scheduled tasks.
