Learning Python with AI: Building a Tkinter Calculator App (Beginner Journey)

 

Learning Python with AI: Building a Tkinter Calculator App (Beginner Journey)

Learning Python feels exciting—until the moment your code looks perfect but nothing works.

That’s exactly what happened to me.

I built my first Python calculator with the help of AI. The UI looked clean. The buttons were there. Everything felt right. But when I clicked the buttons… nothing happened.

No output. No error. Just silence.

If you are a beginner learning Python with AI and you’ve faced something similar, this blog is for you. This is not a polished tutorial written by an expert. This is my real learning experience, the mistakes I made, the confusion I faced, and how I fixed it by understanding one small but powerful concept: event handling.

This is Day 2 of my series AI with Coding, where I learn Python by building real projects step by step.

Why I Chose to Learn Python by Building Projects

My name is Ramdeo2, and this series is called Building Projects and Learning Python with the Help of AI.

I want to be very clear: I am not a Python expert. I am a learner, just like many of you reading this. Instead of only watching tutorials or reading theory, I decided to learn Python by actually building projects.

The reason is simple:

  • Theory feels easy until you write code
  • Real learning happens when something breaks
  • Debugging teaches more than copying code

That’s why this series exists.

What You Need Before Starting This Project

Before you begin, you don’t need anything fancy.

Basic Requirements

  • Python installed on your PC
  • VS Code or any code editor
  • Internet connection
  • Curiosity to learn

If you don’t know how to install Python or run it on your system, don’t panic. You can ask any AI chatbot like ChatGPT, Claude, or others. That’s exactly how beginners should learn today.

AI is not cheating. It’s a learning partner.

Understanding the Environment and AI Prompts

In this project, I am using a simple cloud-based AI interface. There is no special font, no advanced UI, no hidden tools.

It’s just:

  • Writing prompts
  • Getting responses
  • Testing code in VS Code

One very important lesson here is:

AI will only do exactly what you ask it to do. Nothing more. Nothing less.

If your prompt is unclear, your output will be incomplete.

My First Python Calculator Looked Good — But Didn’t Work

For Day 2, I asked AI to generate a simple calculator using Tkinter, which is Python’s built-in GUI library.

The result looked great.

  • Buttons were visible
  • Layout was clean
  • Entry box was present

But when I clicked the buttons… nothing happened.

The Problem

  • Buttons were clickable visually
  • Keyboard input worked
  • No calculation was performed

At first, I thought something was wrong with Tkinter itself.

But the real issue was much deeper.

The Missing Piece: Event Handling in Tkinter

After carefully checking the code, I discovered that the calculator only had UI code.

There was no event handling.

What Is Event Handling? (Beginner Explanation)

Event handling means connecting a button to a function.

For example:

  • When you click +, something should happen
  • When you press =, calculation should run

Without event handling:

  • Buttons look alive
  • But behave like dead text

Example of the Problematic Code (UI Only)

button = Button(root, text="1")

button.grid(row=1, column=0)

This button exists, but it does nothing.

Fixing the Calculator with Proper Event Handling

I went back to AI and clearly explained the problem:

  • Buttons are not working
  • Calculator has no functionality
  • I want an interactive UI

This time, the AI generated a better version.

What Changed in the Second Code

  • Functions were created for each operation
  • Buttons were connected using command=
  • Event handling was implemented

Example of Working Event Handling Code

def click(value):

    entry.insert(END, value)

Button(root, text="1", command=lambda: click(1))

This small change made everything work.

Comparing First Code vs Second Code (Key Learning)

Feature First Code Second Code
UI Design Yes Yes
Button Click No Yes
Event Handling ❌ Missing ✅ Present
Functionality ❌ Not Working ✅ Working

This comparison helped me understand how GUI applications actually work.

Why Learning with AI Is Powerful (If Used Correctly)

Instead of:

  • Giving up
  • Copy-pasting blindly
  • Asking someone else to fix it

I used AI to:

  • Identify the problem
  • Compare outputs
  • Learn missing concepts

AI didn’t just give me code.

It helped me think like a developer.

Your Day 2 Task (Important)

Now it’s your turn.

Task Requirements

  • Build a calculator using Tkinter
  • Change the UI layout
  • Add at least one extra feature

Feature Ideas

  • Dark mode calculator
  • Percentage button
  • Clear history button

Don’t copy my design.

Make it yours.

Final Output and Result

At the end of Day 2:

  • Calculator UI works
  • Buttons respond
  • Logic is functional

More importantly:

I understand why it works.

What’s Coming Next (Day 3)

In Day 3, I’ll show you how to deploy:

  • This calculator
  • Or any Python project

So you can:

  • Share it online
  • Show it to recruiters
  • Build your portfolio

  My LLM Journey: From Curiosity to Building Real AI Agents 🚀 My LLM Journey: From a Curiosity to Building Real AI Agents 💡 The Big Question: What Skills Are Future-Proof? I'm currently in my first year of BSc Computer Science at FICS, and like many others, I found myself constantly grappling with a central question: What skill won’t be replaced in the future? What will still be in high demand? I spent days searching online, often feeling frustrated. With the AI boom, I saw lots of people fearing that their jobs would disappear. But my focus wasn't on fear; I was trying to find the area that would gain real traction in the future. After much reflection, I realized the world is fundamentally changing. Companies no longer need thousands of workers for routine tasks. This led to a more specific question: What can I create that can’t be easily replaced, that allows me to be my own owner, that people truly value, and that represe...
