5 Things You Can Automate With Python: Practical Examples

 5 Things You Can Automate With Python: Practical Examples for Beginners

Introduction

Have you ever spent hours doing the same computer tasks again and again?

Maybe you rename files, organize folders, update Excel spreadsheets, prepare reports, or send the same type of email every day.

These tasks may look simple, but they can take a lot of time when you perform them regularly.

What if your computer could handle these tasks automatically?

This is where Python automation becomes useful.

Python is a popular programming language that allows you to create small programs called scripts. These scripts can perform repetitive tasks automatically, helping you save time and reduce manual work.

The best part is that you don't need to be an expert programmer to start using Python for automation. Even beginners can create simple scripts to organize files, process spreadsheets, and perform other useful tasks.

In this article, we will explore 5 things you can automate with Python, along with practical examples, useful libraries, simple code, and project ideas.

Let's get started!

---

What Is Python Automation?

Python automation means using Python scripts to perform tasks automatically instead of completing every step manually.

In simple words, you give Python a set of instructions, and it performs those instructions for you.

For example, imagine you have 100 PDF files in one folder. You want to rename them using a particular naming format.

Renaming each file manually can take time.

Instead, you can write a Python script that renames all the files automatically.

This is a simple example of Python automation.

Python can automate many types of activities, including:

• File and folder management.
• Excel and spreadsheet operations.
• Email notifications.
• Web browser tasks.
• Data processing.
• Report generation.
• Image processing.
• Database operations.

Now, let's explore five practical things you can automate using Python.

---

1.Automate File and Folder Management

One of the easiest and most useful things you can automate with Python is file and folder management.

Think about your Downloads folder.

It may contain hundreds of files, including:

• PDF documents.
• Excel spreadsheets.
• Word documents.
• Images.
• Videos.
• Text files.

Finding a particular file becomes difficult when everything is stored in one location.

You may spend several minutes searching for the right document or moving files into different folders.

Python can make this process much easier.

What Can You Automate?

Using Python, you can:

• Rename multiple files.
• Move files between folders.
• Copy files automatically.
• Create new folders.
• Organize files by extension.
• Find specific files.
• Check whether a file exists.
• Create backup copies.

Real-World Example

Imagine you work in an office and receive multiple files every day.

You receive:

sales_report.xlsx
invoice.pdf
product_image.jpg
company_logo.png
meeting_notes.txt
presentation.docx

You want to organize these files into separate folders.

The final structure should look like this:

My_Files/
│
├── Documents/
│   ├── invoice.pdf
│   ├── meeting_notes.txt
│   └── presentation.docx
│
├── Images/
│   ├── product_image.jpg
│   └── company_logo.png
│
└── Excel/
    └── sales_report.xlsx

Instead of moving every file manually, Python can identify file extensions and organize them automatically.

Python Code Example: List Files in a Folder

Let's start with a simple example.

import os

folder_path = "My_Files"

files = os.listdir(folder_path)

for file in files:
    print(file)

How Does This Code Work?

• import os imports Python's operating system module.
• folder_path stores the folder location.
• os.listdir() gets the names of files and folders.
• The for loop displays each item.

This is a basic example of reading folder contents.

You can expand this script to organize files based on their extensions.

Useful Python Libraries

Library	Purpose
os	Access files and folders
shutil	Copy and move files
pathlib	Manage file paths
glob	Find files using patterns

Why Is File Automation Useful?

File automation is helpful for office employees, data analysts, developers, e-commerce sellers, and anyone who regularly handles large numbers of files.

It saves time and keeps documents organized.

2. Automate Excel and Spreadsheet Tasks

Excel is one of the most commonly used tools in offices and businesses.

Employees use Excel for sales reports, attendance records, inventory management, financial calculations, and data analysis.

However, working with multiple spreadsheets manually can become time-consuming.

For example, imagine you receive five Excel files every day from five different departments.

You need to:

1. Open every Excel file.
2. Copy the data.
3. Combine all records.
4. Remove duplicate entries.
5. Calculate totals.
6. Prepare a final report.

Doing everything manually can take a lot of time.

Python can automate many of these steps.

What Can You Automate in Excel?

With Python, you can:

• Read Excel files.
• Create new spreadsheets.
• Combine multiple Excel files.
• Remove duplicate records.
• Find missing values.
• Calculate totals.
• Filter data.
• Generate summaries.
• Update spreadsheet information.
• Create automated reports.

Real-World Example

Suppose you work as an MIS Executive or Data Analyst.

Every day, you receive an Excel file containing sales information.

Your manager wants to know the total sales amount.

Instead of opening Excel and calculating everything manually, you can use Python.

Python Code Example: Read an Excel File

import pandas as pd

# Read Excel file
data = pd.read_excel("sales.xlsx")

# Display first five records
print(data.head())

# Calculate total sales
total_sales = data["Sales"].sum()

print("Total Sales:", total_sales)

How Does This Code Work?

• import pandas as pd imports the pandas library.
• read_excel() reads the Excel file.
• head() displays the first five records.
• sum() calculates the total sales amount.

Make sure your spreadsheet contains a column named Sales and that the values are suitable for calculation.

3. Automate Email Notifications

Sending emails is a common activity in almost every organization.

Employees send daily reports, meeting reminders, payment notifications, customer updates, and other business messages.

If you send the same type of email regularly, Python can help automate the process.

For example, imagine you prepare a daily sales report and send it to your manager every evening.

You can create a Python script that prepares an email and sends the report as an attachment through an authorized email service.

What Can You Automate With Email?

Python can help you:

• Send automatic email notifications.
• Send daily reports.
• Attach PDF or Excel files.
• Send reminders.
• Notify employees about completed tasks.
• Send system alerts.
• Prepare scheduled email summaries.

Real-World Example

Imagine a company generates a daily operations report.

After creating the report, the system needs to notify the manager.

The automated process could look like this:

Generate Daily Report
        |
        v
Prepare Email
        |
        v
Attach Report
        |
        v
Send Email
        |
        v
Manager Receives Notification

Instead of manually preparing the same email every day, Python can handle the repetitive steps.

Python Code Example: Create an Email Message

Python provides built-in modules for working with email messages.

Here is a simple example:

from email.message import EmailMessage

message = EmailMessage()

message["Subject"] = "Daily Sales Report"
message["From"] = "sender@example.com"
message["To"] = "manager@example.com"

message.set_content(
    "Hello, please find the daily sales report attached."
)

print(message)

This example creates an email message but does not send it.

To send an email, you can connect it to an authorized SMTP server or use an email provider's API.

Useful Python Libraries

Library	Purpose
email	Create email messages
smtplib	Send emails using SMTP
ssl	Secure network connections
schedule	Schedule simple recurring tasks

1. Open the website.
2. Enter test login details.
3. Click the login button.
4. Check whether the dashboard appears.
5. Record the result.

Python browser automation can perform these steps using an authorized test account.

This makes repeated testing easier.

Python Code Example: Open a Website Using Selenium

First, install Selenium:

pip install selenium

Now write this Python code:

from selenium import webdriver

# Start Chrome browser
driver = webdriver.Chrome()

# Open website
driver.get("https://www.python.org")

# Display website title
print(driver.title)

# Close browser
driver.quit()

How Does This Code Work?

• webdriver imports Selenium's browser automation tools.
• webdriver.Chrome() starts a Chrome browser session.
• get() opens the specified website.
• driver.title retrieves the webpage title.
• quit() closes the browser session.

This is a basic example of browser automation.

More advanced scripts can interact with website elements, fill forms, and test complete workflows.

Real-World Example

Imagine you work in an e-commerce company.

Your team receives daily order information containing:

• Order ID.
• Product name.
• Order amount.
• Delivery status.
• Customer location.
• Return status.

Your manager wants a daily report showing:

• Total orders.
• Delivered orders.
• Cancelled orders.
• Returned orders.
• Total sales.
• Product-wise performance.

Instead of calculating every metric manually, you can use Python to process the data.

Python Code Example: Calculate Order Status

import pandas as pd

# Read order data
data = pd.read_csv("orders.csv")

# Count orders by status
status_summary = data["Status"].value_counts()

# Calculate total order amount
total_amount = data["Amount"].sum()

print("Order Summary:")
print(status_summary)

print("Total Amount:", total_amount)

How Does This Code Work?

• read_csv() reads the CSV file.
• value_counts() counts how many times each order status appears.
• sum() calculates the total amount.
• print() displays the results.

Your CSV file should contain columns named Status and Amount.
