Topic: Python – Create IP Address Tracker GUI using Tkinter

---

### What You'll Build

A desktop app that allows the user to:

• Enter an IP address or domain
• Fetch geolocation data (country, city, ISP, etc.)
• Display it in a user-friendly Tkinter GUI

We'll use the requests library and a free API like ip-api.com.

---

### Step-by-Step Code

import tkinter as tk
from tkinter import messagebox
import requests

# Function to fetch IP information
def track_ip():
    ip = entry.get().strip()
    if not ip:
        messagebox.showwarning("Input Error", "Please enter an IP or domain.")
        return

    try:
        url = f"https://ip-api.com/json/{ip}"
        response = requests.get(url)
        data = response.json()

        if data["status"] == "fail":
            messagebox.showerror("Error", data["message"])
            return

        # Show info
        result_text.set(
            f"IP: {data['query']}\n"
            f"Country: {data['country']}\n"
            f"Region: {data['regionName']}\n"
            f"City: {data['city']}\n"
            f"ZIP: {data['zip']}\n"
            f"ISP: {data['isp']}\n"
            f"Timezone: {data['timezone']}\n"
            f"Latitude: {data['lat']}\n"
            f"Longitude: {data['lon']}"
        )

    except Exception as e:
        messagebox.showerror("Error", str(e))

# GUI Setup
app = tk.Tk()
app.title("IP Tracker")
app.geometry("400x400")
app.resizable(False, False)

# Widgets
tk.Label(app, text="Enter IP Address or Domain:", font=("Arial", 12)).pack(pady=10)

entry = tk.Entry(app, width=40, font=("Arial", 12))
entry.pack()

tk.Button(app, text="Track IP", command=track_ip, font=("Arial", 12)).pack(pady=10)

result_text = tk.StringVar()
result_label = tk.Label(app, textvariable=result_text, justify="left", font=("Courier", 10))
result_label.pack(pady=10)

app.mainloop()

---

### Requirements

Install the requests library if not already installed:

pip install requests

---

### Exercise

• Enhance the app to export the result to a .txt or .csv file
• Add a map preview using a web view or link to Google Maps
• Add dark mode toggle for the GUI

# 📚 PyQt5 Tutorial - Part 1/6: Introduction to GUI Programming
#PyQt5 #Python #GUI #BeginnerFriendly #Qt

Welcome to Part 1 of our comprehensive PyQt5 series! This lesson will introduce you to GUI development with Python and PyQt5, perfect for beginners.

---

## 🔹 What is PyQt5?
PyQt5 is a set of Python bindings for Qt (a powerful C++ GUI framework). It lets you create:
- Desktop applications
- Cross-platform GUIs
- Professional-looking interfaces
- Apps with databases, networking, and multimedia

Key Features:
✔️ 620+ classes
✔️ 6,000+ functions
✔️ Windows, Mac, Linux support
✔️ Open-source (GPL/commercial licenses)

---

## 🔹 Installation
Install PyQt5 and tools:

pip install PyQt5 PyQt5-tools

Verify Installation:

import PyQt5
print(PyQt5.__version__)  # Should show version like 5.15.4

---

## 🔹 Your First PyQt5 App
Let's create a simple window:

import sys
from PyQt5.QtWidgets import QApplication, QLabel, QWidget

# 1. Create the application object
app = QApplication(sys.argv)

# 2. Create main window
window = QWidget()
window.setWindowTitle("My First App")
window.setGeometry(100, 100, 400, 200)  # x, y, width, height

# 3. Add a label
label = QLabel("Hello PyQt5!", parent=window)
label.move(150, 80)  # x, y position

# 4. Show the window
window.show()

# 5. Run the application
sys.exit(app.exec_())

Code Breakdown:
1. QApplication: Manages app control flow
2. QWidget: Base class for all UI objects
3. QLabel: Displays text/images
4. exec_(): Starts the event loop

---

## 🔹 Core PyQt5 Components
### 1. Main Window Types
| Class | Purpose |
|-------|---------|
| QWidget | Basic empty window |
| QMainWindow | With menu bar, status bar, toolbars |
| QDialog | Popup dialog windows |

### 2. Common Widgets

from PyQt5.QtWidgets import (
    QPushButton,  # Clickable button
    QLineEdit,    # Single-line text input
    QTextEdit,    # Multi-line text area
    QCheckBox,    # Toggle option
    QRadioButton, # Exclusive choice
    QComboBox,    # Dropdown menu
    QSlider       # Value selector
)

### 3. Layout Managers

from PyQt5.QtWidgets import (
    QVBoxLayout,  # Vertical arrangement
    QHBoxLayout,  # Horizontal arrangement
    QGridLayout   # Grid arrangement
)

---

## 🔹 Creating a Functional App
Let's build a temperature converter:

import sys
import csv
from PyQt5.QtWidgets import *
import database as db # Import our database module

class WarehouseApp(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("Warehouse ERP System")
        self.setGeometry(100, 100, 1000, 700)
        db.setup_database() # Ensure tables are created

        self.tabs = QTabWidget()
        self.setCentralWidget(self.tabs)
        
        # Create tabs
        self.inventory_tab = QWidget()
        self.purchase_tab = QWidget() # Incoming
        self.sales_tab = QWidget()    # Outgoing
        self.production_tab = QWidget()
        self.reports_tab = QWidget()

        self.tabs.addTab(self.inventory_tab, "Inventory")
        # Add other tabs later...

        self.setup_inventory_ui()
        self.load_inventory_data()

    def setup_inventory_ui(self):
        layout = QVBoxLayout()
        # Table view
        self.inventory_table = QTableWidget()
        self.inventory_table.setColumnCount(4)
        self.inventory_table.setHorizontalHeaderLabels(['ID', 'Name', 'Quantity', 'Price'])
        self.inventory_table.setEditTriggers(QAbstractItemView.NoEditTriggers)
        layout.addWidget(self.inventory_table)
        
        # Form for adding new items
        form = QFormLayout()
        self.item_name = QLineEdit()
        self.item_qty = QSpinBox()
        self.item_qty.setRange(0, 99999)
        self.item_price = QLineEdit()
        form.addRow("Name:", self.item_name)
        form.addRow("Quantity:", self.item_qty)
        form.addRow("Price:", self.item_price)
        add_btn = QPushButton("Add New Item")
        add_btn.clicked.connect(self.add_item)
        layout.addLayout(form)
        layout.addWidget(add_btn)
        
        self.inventory_tab.setLayout(layout)

    def load_inventory_data(self):
        items = db.get_inventory()
        self.inventory_table.setRowCount(len(items))
        for row_num, row_data in enumerate(items):
            for col_num, data in enumerate(row_data):
                self.inventory_table.setItem(row_num, col_num, QTableWidgetItem(str(data)))

    def add_item(self):
        name = self.item_name.text()
        qty = self.item_qty.value()
        price = float(self.item_price.text())
        if not name:
            QMessageBox.warning(self, "Input Error", "Item name cannot be empty.")
            return
        if db.add_inventory_item(name, qty, price):
            self.load_inventory_data() # Refresh table
            self.item_name.clear()
            self.item_qty.setValue(0)
            self.item_price.clear()
        else:
            QMessageBox.warning(self, "DB Error", f"Item '{name}' already exists.")

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = WarehouseApp()
    window.show()
    sys.exit(app.exec_())

#Step 3: Purchase (Incoming) and Sales (Outgoing) Tabs

We'll manage invoices. A purchase increases stock, and a sale decreases it. We need to add functions to database.py first, then build the UI.

Add to database.py:
