2.1 Installing Python

2.1 Installing Python

Key Concepts

Before diving into Django, it's essential to have Python installed on your system. Python is the foundational language for Django, and having the correct version is crucial for compatibility and performance.

1. Python Version

Python comes in two major versions: Python 2 and Python 3. Django, however, requires Python 3. It's important to install the latest stable version of Python 3 to ensure compatibility with the latest Django features and security updates.

2. Installation Process

The installation process varies depending on your operating system. Below are the steps for Windows, macOS, and Linux.

Windows

To install Python on Windows:

  1. Visit the official Python website: https://www.python.org/downloads/.
  2. Download the latest version of Python 3 for Windows.
  3. Run the installer and ensure to check the box that says "Add Python to PATH" during installation.
  4. Complete the installation and verify by opening Command Prompt and typing python --version.

macOS

To install Python on macOS:

  1. Visit the official Python website: https://www.python.org/downloads/.
  2. Download the latest version of Python 3 for macOS.
  3. Run the installer and follow the on-screen instructions.
  4. Verify the installation by opening Terminal and typing python3 --version.

Linux

To install Python on Linux:

  1. Open Terminal.
  2. Update the package list using sudo apt-get update.
  3. Install Python 3 using sudo apt-get install python3.
  4. Verify the installation by typing python3 --version.

3. Virtual Environments

A virtual environment is an isolated Python environment that allows you to manage dependencies for different projects. This is particularly useful when working on multiple Django projects with different requirements.

To create a virtual environment: 

python3 -m venv myenv

To activate the virtual environment: 

# On Windows
myenv\Scripts\activate

# On macOS and Linux
source myenv/bin/activate

4. Verifying Installation

After installing Python and setting up a virtual environment, you can verify the installation by running a simple Python script. 

# Create a new Python file
echo "print('Hello, Django!')" > hello.py

# Run the script
python3 hello.py

If the output is "Hello, Django!", then Python is installed correctly.
