Python is one of the most versatile coding languages you can learn.

Today, you'll take a leap into programming by writing your very first Python script. Excited? You should be!

Understanding Python: A Quick Overview

Before we dive into writing code, let's understand what Python is. Python is a high-level, interpreted programming language known for its simplicity and readability. It's widely used in web development, data analysis, artificial intelligence, and more.

Think of Python as a Swiss Army knife for programmers. Just like a Swiss Army knife, Python is versatile, user-friendly, and incredibly useful in a variety of scenarios.

Setting Up Your Python Environment

To kick off, you'll need the Python interpreter. Here's how you can set it up on Mac and Windows:

For Mac Users:

Good news! Your Mac comes with Python pre-installed. To verify and start using it:

  1. Open Terminal (you can find it in Applications > Utilities).
  2. Type python --version and press Enter. You should see the Python version number. If Python is not installed, it will prompt you to install it.
  3. To start Python, just type python and hit Enter. You're now in the Python interpreter!

For Windows Users:

Windows doesn't come with Python, but don't worry, it's easy to install:

  1. Visit the official Python website at Python Downloads.
  2. Download the latest version for Windows.
  3. Run the installer. Make sure to check the box that says "Add Python to PATH" before clicking "Install Now".
  4. After installation, open Command Prompt.
  5. Type python --version to check if it's installed correctly.
  6. Start Python by typing python and hitting Enter.

Your Mission: Write and Run Your First Python Script

Opening Terminal on Mac:

To open the Terminal on a Mac, you have a couple of easy options. First, you can find it in your Applications folder. Go to Finder, select 'Applications', then open the 'Utilities' folder. Inside, you'll find the Terminal app. Alternatively, for a quicker route, use Spotlight Search – press Command + Spacebar, type "Terminal", and hit Enter. This will bring up the Terminal window, where you can start entering your Python commands.

Opening Command Prompt on Windows:

For Windows users, accessing the Command Prompt is straightforward. You can search for it by clicking the Start menu or pressing the Windows key. Just type "cmd" or "Command Prompt" in the search bar, and you'll see the Command Prompt app in the search results. Click on it to open. Another quick way is to press Windows + R to open the Run dialog, type "cmd" in the box, and press Enter. This will also launch the Command Prompt, ready for your Python adventures.

Let's write some code:

After opening your Terminal (Mac) or Command Prompt (Windows). Type python and press Enter to open the Python interpreter. This is called interactive mode because your Python commands are interpreted immediately and output is generated. Type the following code:

print("Hello, Python world!")

Press Enter. You should see "Hello, Python world!" displayed. Congratulations, you've just run your first Python script!

When you want to exit python interactive mode just type exit().
