or, for systems where Python 3 is the default:

bash
python3 –version

This will display the version number of Python currently in use, allowing you to determine whether an upgrade is necessary.

Upgrading Python on macOS

If you’re using macOS, the easiest way to upgrade Python is through Homebrew, a popular package manager. Follow these steps:

  1. Update Homebrew to ensure you have the latest version of the package information:

bash
brew update

  1. Upgrade Python by running:

bash
brew upgrade python

After the upgrade completes, verify the installation by checking the version again.

Upgrading Python on Ubuntu

For Ubuntu users, you can upgrade Python using the Advanced Package Tool (APT). Here’s how:

  1. First, update the package list:

bash
sudo apt update

  1. Then, upgrade Python:

bash
sudo apt upgrade python3

  1. Confirm the upgrade by checking the version:

python3 –version

Upgrading Python on Windows

To upgrade Python on Windows, the recommended method is to download the latest installer from the official Python website. However, you can also use the command line for installations if Python was installed using the Windows Store.

  1. Open the Command Prompt and run:

bash
python -m pip install –upgrade pip

  1. After upgrading pip, you can upgrade Python by downloading the latest executable installer. Run the installer, and ensure to check the box that says “Add Python to PATH”.
  1. Verify the upgrade:

bash
python –version

Using Pyenv to Manage Python Versions

For users who need to manage multiple Python versions, Pyenv is a powerful tool. You can install Pyenv and use it to install or upgrade Python easily. Here’s a brief guide:

  1. Install Pyenv by following the instructions on the official [Pyenv GitHub page](https://github.com/pyenv/pyenv).
  1. Once installed, you can install a new version of Python:

bash
pyenv install 3.x.x

  1. Set the global Python version:

bash
pyenv global 3.x.x

  1. Check the currently active Python version:

bash
python –version

Operating System Upgrade Command Version Check Command
macOS brew upgrade python python3 –version
Ubuntu sudo apt upgrade python3 python3 –version
Windows Download Installer python –version
Any pyenv install 3.x.x python –version

By following these procedures, you can ensure that your Python installation is up to date, enabling you to take advantage of the latest features and improvements.

Checking Your Current Python Version

Before upgrading Python, it is essential to know your current version. This can be done easily through the terminal.

  • Open your terminal (Command Prompt for Windows, Terminal for macOS and Linux).
  • Type the following command and press Enter:

bash
python –version

or

bash
python3 –version

  • The output will display the current version of Python installed on your system.

Upgrading Python on macOS

For macOS users, the preferred method of upgrading Python is through Homebrew, a package manager for macOS.

  1. First, ensure Homebrew is installed. If not, install it by entering the following command in your terminal:

bash
/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)”

  1. Once Homebrew is installed, update it:

bash
brew update

  1. Upgrade Python by running:

bash
brew upgrade python

  1. Verify the upgrade:

bash
python3 –version

Upgrading Python on Linux

Linux users can upgrade Python using the package manager specific to their distribution.

  • Debian/Ubuntu:

bash
sudo apt update
sudo apt upgrade python3

  • Fedora:

bash
sudo dnf upgrade python3

  • Arch Linux:

bash
sudo pacman -Syu python

After the upgrade, check the version:

bash
python3 –version

Upgrading Python on Windows

On Windows, the easiest way to upgrade Python is through the official installer.

  1. Download the latest version of Python from the [official Python website](https://www.python.org/downloads/).
  2. Run the installer.
  3. Ensure to check the box that says “Add Python to PATH” during installation.
  4. Choose “Upgrade Now” when prompted.

To verify the installation, open Command Prompt and check the version:

bash
python –version

Using Pyenv for Python Management

For users who need to manage multiple Python versions, `pyenv` is a powerful tool. It allows seamless switching between versions.

  1. Install `pyenv` by following the instructions on the [pyenv GitHub page](https://github.com/pyenv/pyenv).
  2. Install a new version of Python:

bash
pyenv install

  1. Set the global Python version:

bash
pyenv global

I’m Leonard a developer by trade, a problem solver by nature, and the person behind every line and post on Freak Learn.

I didn’t start out in tech with a clear path. Like many self taught developers, I pieced together my skills from late-night sessions, half documented errors, and an internet full of conflicting advice. What stuck with me wasn’t just the code it was how hard it was to find clear, grounded explanations for everyday problems. That’s the gap I set out to close.

Freak Learn is where I unpack the kind of problems most of us Google at 2 a.m. not just the “how,” but the “why.” Whether it's container errors, OS quirks, broken queries, or code that makes no sense until it suddenly does I try to explain it like a real person would, without the jargon or ego.
