Build a Square Calculator App with PyQt6 | Python GUI Tutorial for Beginners (VS Code)
📄 Description:
Welcome back to another Python GUI tutorial! 👋 In this video, we're upgrading our skills by building a Square Calculator app using PyQt6 and VS Code. You'll learn step-by-step how to set up your workspace and write Python code that takes a number input, computes its square, and displays the result. Perfect for beginners eager to practice Python GUI development!✨
✅ What You'll Learn:
1️⃣ Set up your workspace:
Open VS Code.
Go to the File menu ➔ Add Folder to Workspace...
Create a new folder named: AI_PyQt6_App.
Open this folder in your workspace.
2️⃣ Create the virtual environment:
Open the Terminal menu ➔ New Terminal.
In the Terminal panel, choose Git Bash (or your preferred terminal).
Type the following command to create a virtual environment:
💻 Windows:
python -m venv .venv_AI
💻 MacOS/Linux:
python3 -m venv .venv_AI
💻 Activate the environment:
source .venv_AI/Scripts/activate
3️⃣ Install PyQt6:
First, upgrade pip:
python -m pip install --upgrade pip
Then install PyQt6:
pip install PyQt6
4️⃣ Check installed libraries:
Verify your setup:
pip list
🚀 Build a Square Calculator App:
We’re creating a simple PyQt6 app that:
Takes a number input (name_input).
Computes the square when you click "Compute Square".
Displays the result in a label (greeting_label).
💻 Full Python Script:
from PyQt6.QtWidgets import QApplication, QWidget, QLabel, QPushButton, QVBoxLayout, QLineEdit
import sys
def compute_square():
try:
num = int(name_input.text())
greeting_label.setText(f"Square = {num * num}")
except ValueError:
greeting_label.setText("Please enter a valid integer")
app = QApplication(sys.argv)
window = QWidget()
window.setWindowTitle("Compute Square App")
Widgets
name_input = QLineEdit()
name_input.setPlaceholderText("Enter a number")
greet_button = QPushButton("Compute Square")
greet_button.clicked.connect(compute_square)
greeting_label = QLabel("")
Layout
layout = QVBoxLayout()
layout.addWidget(name_input)
layout.addWidget(greet_button)
layout.addWidget(greeting_label)
window.setLayout(layout)
window.show()
sys.exit(app.exec())
💡 Tips:
Always validate your input to avoid errors—notice how we handle invalid integers gracefully! ✅
This is a simple math app, but you can expand it to handle more complex calculations next.
