Setup Environment

Before we dive into Python programming, we need to set up your development environment. This includes installing Python and choosing a code editor.

Installing Python

1. Download Python:
   • Visit the official Python website.
   • Download the latest version for your operating system.
2. Install Python:
   • Run the installer.
   • Make sure to check the box that says “Add Python to PATH” during installation.
   • Follow the installation prompts.
3. Verify Installation:
   • Open a terminal or command prompt.
   • Type the command:

     python --version
     

   • You should see the installed Python version.

Choosing a Code Editor

A code editor is where you’ll write your Python code. Here are some popular options:

• VS Code (Recommended):
  • Download from Visual Studio Code.
  • Install the Python extension for syntax highlighting and debugging.
• PyCharm:
  • Ideal for larger Python projects.
  • Download from JetBrains PyCharm.
• Other Options: Sublime Text, Atom, or even a simple text editor.

Setting Up VS Code for Python

1. Install VS Code:
   • Download and install from the official website.
2. Install the Python Extension:
   • Open VS Code.
   • Go to the Extensions view (Ctrl+Shift+X).
   • Search for “Python” and install the extension by Microsoft.
3. Verify the Setup:
   • Open a new file and save it with a .py extension (e.g., hello.py).
   • Type the following code:

     print("Hello, Python!")
     

   • Run the file by pressing Ctrl+Shift+B or using the Run option.

Testing Your Setup

1. Open a terminal in your code editor.
2. Navigate to the folder where your Python file is saved.
3. Run the file with:

   python hello.py
   

4. You should see the output:

   Hello, Python!
   

Now that your environment is ready, you’re all set to begin your Python journey!
