Introduction to Automation Scripts
Automation scripts can:
-
Save time
-
Reduce human effort
-
Minimize errors
-
Increase efficiency
- An automation script is a program that automatically performs tasks that would otherwise be done manually.
- Automation scripting is the process of writing programs that perform repetitive tasks automatically without manual intervention.
- Python is one of the most popular languages for automation because of its simple syntax and powerful libraries.
Need and Benefits of Automation
Automation is needed because many computer tasks are:
-
Repetitive
-
Time-consuming
-
Error-prone
1.File Handling Tasks
Automatically organizing downloaded files into folders.
Moving files
Renaming files
Creating files
Types of Tasks that can be Automated
Deleting files
2. System Administration Tasks
A script checks CPU and memory usage every hour and saves the report.
User management
System monitoring
Process management
Backup creation
3. Web Automation
Using Python and Selenium to automatically log in to a website.
User management
Data scraping
Backup creation
4. Network Automation
Automatically pinging multiple servers to check connectivity.
Scanning networks
Monitoring devices
Checking server status
6. Email Automation
Automatically sending exam result notifications to students.
Sending automatic emails
Notifications and alerts
Generating reports
7. Data Processing
Reading sales data from Excel and generating summary reports

Determine which repetitive task needs automation.
Example:- Automatically
renaming files.
2.Identify the Task
Create the Python program to perform the task.
4.Write the Script
3.Choose Required Libraries
Select suitable Python libraries.
Task Scheduler (Windows)
Cron Jobs (Linux)
6.Automate Execution
5.Test the Script
Check whether the script works correctly.
Basic Steps in Writing an Automation Script
1.Analyze the Process
Inputs
Outputs
Required actions
import os
for i in range(1, 6):
folder_name = f"Folder_{i}"
os.mkdir(folder_name)
print("Folders created successfully")Explanation
-
os.mkdir() creates folders
-
Loop creates multiple folders automatically
