To update Python on Windows, first, check your current Python version by running python -V in the command prompt. Then, go to the Python’s official website, download the installer for the version you wish to update to, and run it, ensuring you select the option to add python.exe to the PATH.
On Linux, check your current version with python3 --version, then add the Deadsnakes repository using sudo add-apt-repository ppa:deadsnakes/ppa. Refresh the cache with sudo apt update, then install the new version with sudo apt install python3.x (replace x with the desired version number). If you have multiple versions, set the default version using the update-alternatives command.
On a Mac, use Homebrew to manage your Python version. If you don’t have Homebrew installed, install it with /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)". To upgrade Python, run brew install python3 if upgrading from Python 2 to 3, or brew upgrade python3 to upgrade to the latest Python 3 version.
Let’s dive deeper into the matter next! 
Overview of Python Versions
Python is a widely used programming language known for its simplicity and ease of use. In this section, we will discuss the latest Python versions and how you can determine which version you are currently using.

How to Check Your Python Version
Before updating your Python version, it’s important to know the current version installed on your system. This will help you determine if an update is necessary and which version to upgrade to. You can check your Python version through the command prompt or terminal window.
On Windows, press Win + R and type cmd to open the command prompt. Enter the following command and press Enter:
python --version
Alternatively, for Python 3, try:
python3 --version
On macOS and Linux systems, open your terminal window by pressing Ctrl + Alt + T and type in the following command, then press Enter:
python --version
Or for Python 3:
python3 --version
Your Python version will be displayed as output, showing something like "Python 3.8.5" or "Python 3.9.0". This information will help you determine if you need to update Python and guide you in choosing the appropriate version for your system.
Updating Python on Different Operating Systems
In this section, we will discuss how to update your Python version on different operating systems, including Windows, macOS, and Linux.
Python Installation on Windows
To update Python on Windows 10, you can either download the installer from the Python official website or search for the app in the Microsoft Store. Select the appropriate version (32-bit or 64-bit) depending on your Windows system and follow the instructions provided by the installer. Alternatively, you can use the command prompt to update Python by running commands with the py launcher after installing the new version.
Python Installation on MacOS
On macOS, you can update Python by using the Homebrew package manager. First, install Homebrew if you haven’t already. Next, run brew install python to install the latest version of Python. If you prefer to download the package directly, you can visit the Python official website and follow the installation steps.
Python Installation on Linux
For Linux users, updating Python depends on the distribution you’re using. On Ubuntu or any Debian-based system, you can update Python using the apt package manager. First, add the Deadsnakes PPA to your repository list:
sudo add-apt-repository ppa:deadsnakes/ppa sudo apt-get update
Then, install the latest Python version with this command:
sudo apt-get install python3.x
Replace “x” with the desired version number, such as “9” for Python 3.9.
For other Linux distributions, consult your distribution’s package manager documentation to find the appropriate steps for updating Python.
Update Python with Different Package Managers
In this section, we will cover how to update your Python version using different package managers, such as Pip, Conda, and Chocolatey. We will discuss each package manager and how to easily upgrade your Python installation.
Upgrading Python with Pip
Pip is the default package manager for Python, making it simple to install and manage Python packages. However, it doesn’t directly update the core Python installation. To update Python using pip, you can use virtual environments and switch between different Python versions.
Here’s a quick guide on how to create a virtual environment with a specific Python version:
- Install the desired version of Python from the official website.
- Install
virtualenvif not already installed:pip install virtualenv. - Create a new virtual environment with the specific Python version:
virtualenv -p /path/to/pythonX.X myenv. - Activate the virtual environment:
source myenv/bin/activate(for Linux/Mac) ormyenv\Scripts\activate(for Windows).
Now, you can use this virtual environment to work with the updated Python version.
Upgrading Python with Conda
The Conda package manager is primarily used with the Anaconda distribution of Python. It can manage packages, environments, and different Python versions. To upgrade Python using Conda, follow these steps:
- Open a terminal or Anaconda Prompt.
- Update the
condapackage manager:conda update conda. - List available Python versions:
conda search "^python$. - Choose the desired Python version and update your environment:
conda install python=X.X.
Conda will upgrade Python within your current environment, making it easy to work with different versions of Python.
Upgrading Python with Chocolatey
Chocolatey is a package manager for Windows which can be used to update your Python installation. To upgrade Python using Chocolatey, follow these steps:
- Install Chocolatey by following the official installation guide.

choco upgrade python.
Chocolatey will download and install the latest Python version, ensuring that your Python environment is up-to-date.
Troubleshooting Python Upgrade Issues
Sometimes, when upgrading your Python version, you may encounter issues or errors. In this section, we will discuss some common problems and provide solutions to help you rectify them.
First, ensure that you have properly installed the new Python version. For example, if you are upgrading to Python 3.9, follow the instructions to update Python, which includes adding the deadsnakes PPA, updating the apt cache, and installing the new package.
If you are facing issues with package dependencies, it might be beneficial to create a new virtual environment with the desired Python version using the venv module. For example, run python3.9 -m venv new_environment_name. After activating the new environment, reinstall your packages using pip. This can help address conflicts between dependencies and ensure you are using the latest package versions.
In case some packages are not compatible with the newest Python version, you might need to check for updates or bug fixes from the package developers. This information can typically be found on the package’s GitHub repository or documentation.
