Starting My Python Journey — By Raees Yaqoob Qazi (DevOps Engineer)

 Today, I’m starting my Python learning journey.

 Before we begin, please make sure you have VS Code and Python installed on your machine.
 Both installations are very simple — just download the .exe files, run them, and keep clicking Next. Within a minute, everything will be ready to use.

Why is Python Important? Why Should We Learn It?

The answer is very simple:

  • Python is easy to read and easy to write.
     Its syntax is clean and beginner-friendly.
  • Python has a huge community.
     You will always find support, tutorials, and ready-made solutions online.
  • Python has powerful libraries for almost every domain.

For example:

  • For DevOps & AWS automation → boto3
  • For SQL databases → pymysql
  • For MongoDB → pymongo

This is why Python is one of the most in-demand programming languages in the world.

After learning Python, it becomes easier to find jobs, work on DevOps tasks, or even earn from freelance platforms.




Understanding Hardware and Operating Systems

Let’s make it simple:

  • Hardware is just a physical box (computer/laptop/server).
     Alone, it cannot do anything.

To use hardware resources, we must install an Operating System (OS) on it.

Common OS options are:

1. Windows

  • Owned by Microsoft
  • Updates are released anytime
  • Very user-friendly

2. macOS

  • Owned by Apple
  • Based on UNIX
  • Known for stability and performance

3. Linux

  • Open-source (we can contribute to its development)
  • Stable and widely used in servers and DevOps
  • Has fixed update cycles
  • April → version ends with .04
  • October → version ends with .10

Example:

  • Ubuntu 20.04 → April release
  • Ubuntu 20.10 → October release

How Do We Give Instructions to an Operating System?

When we write something like:

print("Hi")

We are using a high-level language (Python).
 To understand this code, Python uses:

Interpreter

  • Converts code line by line into machine language.

Compiler

  • Converts the full program at once into machine language.
  • Example: When we build a Django project, the compiler processes the entire codebase.

This is how our simple instructions are translated so the operating system can execute them.

Final Words

I hope you found my blog helpful and easy to understand.
 If you liked it, please share it with others so they can also start learning Python.

My First Python Program: A Simple Calculator

Image
 Today, I am going to create a simple calculator using Python . This might be your first code ever , and honestly, this is also my first Python code . So don’t worry — we are learning together. Let’s start step by step. Step 1: Open VS Code First, open Visual Studio Code (VS Code) . Step 2: Create a Folder and a File Create a new folder (you can name it anything). Inside the folder, create a new file. In my case, I named the file first.py . 👉  .py is the file extension for Python , just like: .cpp for C++ .java for Java Step 3: Write the Python Code Now, write the following code in first.py : num1 = float ( input ( "Enter num 1: " ) ) # Taking first number from the user num2 = float ( input ( "Enter num 2: " ) ) # Taking second number from the user opr = input ( "Enter operator: " ) # User selects the operator (+, -, *) if opr = = "+" : # If operator is + output = num1 + num2 if opr = = "-" : # If operator is - ...
