Installing Python (Windows, macOS, Linux)

Module 1: Installing Python (Windows, macOS, Linux)

To start your Python programming journey, the first step is to install Python on your system. Whether you're using Windows, macOS, or Linux, Python installation is straightforward and easy to follow. In this module, we’ll guide you through the steps for each operating system.

Installing Python on Windows

Follow these steps to install Python on a Windows system:

Visit the Python Downloads page.
Download the latest version for Windows.
Run the installer and select the “Add Python to PATH” option.
Click on “Install Now” and wait for the process to complete.
Verify the installation by opening the Command Prompt and typing:
```
    python --version
    
```

Tip: Make sure to check the “Add Python to PATH” option during installation. This ensures Python can be accessed from the command line.

Installing Python on macOS

Python comes pre-installed on macOS, but it’s usually an older version. Follow these steps to install the latest Python version:

Download the latest macOS installer from the Python Downloads page.
Run the installer and follow the instructions.
Once installed, open the Terminal and verify the installation by typing:
```
    python3 --version
    
```
For package management, consider installing Homebrew and managing Python using:
```
    brew install python
    
```

Installing Python on Linux

Most Linux distributions come with Python pre-installed. However, you can update or install Python manually:

Update your package list:
```
    sudo apt update
    
```
Install Python:
```
    sudo apt install python3
    
```
Verify the installation:
```
    python3 --version
    
```

Tip: Use a package manager like yum, dnf, or apt depending on your Linux distribution.

Common Issues and Troubleshooting

Here are solutions to some common issues:

Python Not Found: Ensure Python is added to the PATH environment variable.
Outdated Python Version: Download the latest installer from the Python website.
Permission Errors: Run the installer or command with administrator/root privileges.
