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"http://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.noscript("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

Your biggest enemy 𝐅𝐄𝐀𝐑 𝐨𝐟 𝐑𝐞𝐣𝐞𝐜𝐭𝐢𝐨𝐧

People hesitate to apply for many opportunities just because of fear of rejection.

However, not applying means you are automatically rejecting yourself. They usually think I will start applying after 6-8 months with full preparation.

Do you really think it will work ??? Interview calls usually take months 😅

My suggestion would be to start applying after 10 days to 1 month of preparation . Try to give as many interviews as you can. In this way, you will learn 👇🏻

🌴 Frequently asked questions
🌴 Interview pattern
🌴 How to tweak your answers?

Give a try ,even in the worst scenario, you will get some interview experience. That experience will eventually help you in the future

All the best 👍👍

SQL Basics for Beginners: Must-Know Concepts

1. What is SQL?
SQL (Structured Query Language) is a standard language used to communicate with databases. It allows you to query, update, and manage relational databases by writing simple or complex queries.

2. SQL Syntax
SQL is written using statements, which consist of keywords like SELECT, FROM, WHERE, etc., to perform operations on the data.
- SQL keywords are not case-sensitive, but it's common to write them in uppercase (e.g., SELECT, FROM).

3. SQL Data Types
Databases store data in different formats. The most common data types are:
- INT (Integer): For whole numbers.
- VARCHAR(n) or TEXT: For storing text data.
- DATE: For dates.
- DECIMAL: For precise decimal values, often used in financial calculations.

4. Basic SQL Queries
Here are some fundamental SQL operations:

- SELECT Statement: Used to retrieve data from a database.

     SELECT column1, column2 FROM table_name;
     

- WHERE Clause: Filters data based on conditions.

     SELECT * FROM table_name WHERE condition;
     

- ORDER BY: Sorts data in ascending (ASC) or descending (DESC) order.

     SELECT column1, column2 FROM table_name ORDER BY column1 ASC;
     

- LIMIT: Limits the number of rows returned.

     SELECT * FROM table_name LIMIT 5;
     

5. Filtering Data with WHERE Clause
The WHERE clause helps you filter data based on a condition:

   SELECT * FROM employees WHERE salary > 50000;
   

You can use comparison operators like:
- =: Equal to
- >: Greater than
- <: Less than
- LIKE: For pattern matching

6. Aggregating Data
SQL provides functions to summarize or aggregate data:
- COUNT(): Counts the number of rows.

     SELECT COUNT(*) FROM table_name;
     

- SUM(): Adds up values in a column.

     SELECT SUM(salary) FROM employees;
     

- AVG(): Calculates the average value.

     SELECT AVG(salary) FROM employees;
     

- GROUP BY: Groups rows that have the same values into summary rows.

     SELECT department, AVG(salary) FROM employees GROUP BY department;
     

7. Joins in SQL
Joins combine data from two or more tables:
- INNER JOIN: Retrieves records with matching values in both tables.

     SELECT employees.name, departments.department
     FROM employees
     INNER JOIN departments
     ON employees.department_id = departments.id;
     

- LEFT JOIN: Retrieves all records from the left table and matched records from the right table.

     SELECT employees.name, departments.department
     FROM employees
     LEFT JOIN departments
     ON employees.department_id = departments.id;
     

8. Inserting Data
To add new data to a table, you use the INSERT INTO statement:

   INSERT INTO employees (name, position, salary) VALUES ('John Doe', 'Analyst', 60000);
   

9. Updating Data
You can update existing data in a table using the UPDATE statement:

   UPDATE employees SET salary = 65000 WHERE name = 'John Doe';
   

10. Deleting Data
To remove data from a table, use the DELETE statement:

    DELETE FROM employees WHERE name = 'John Doe';
