Updating python on linux

In order to update python version on the terminal, you can use these commands depending on your operating system:

1#Linux 2 sudo apt update 3 sudo apt install python3.11 4 5 #MacOS 6brew install python

Here is a detailed guide about how to update python version in other operating systems. In this article, we are going to focus on how to install it on the terminal.

Update Python on Windows

To update Python on Windows you should download the Python version you want to upgrade to from python.org. In case you already have installed different Python versions and want to update the version of a virtual environment, you can do it by using the following command:

1python -m venv --upgrade VIRTUAL-ENVIRONMENT-PATH-HERE

To select which Python version we want to use, it’s as simple as as writing py -version-you-want-to-use , example:

1 py -3.8 #selects Python version 3.8 2 py -3.11 # Selects Python version 3.11 

Updating Python on Linux

Before getting into upgrading Python, we need to know if it’s already installed (no use to upgrade something that doesn’t exist). To check if Python is installed type the following:

If there’s an installed version of Python, the output should show you the installed version like this:

If your computer doesn’t have Python installed, we need first to prepare our system to install Python, so we do the following:

1sudo apt update 2 sudo apt install software-properties-common

Once we have downloaded the necessary files to install Python latest version, we can install it using apt-get (recommended) or using the source code.

Update with Apt-Get

There’s no need to reinvent the wheel, Apt-Get it’s a package manager built in Linux that will make our life easier while installing. As a first step, let’s configure the deadsnakes PPA on the system by running the following command:

1sudo add-apt-repository ppa:deadsnakes/ppa

1sudo apt update 2 sudo apt install python3.9

Python is now updated, but still is pointing to the previously installed version. We need now to update this:

1 sudo update-alternatives --config python3

A list of options will be displayed and prompt to pick the Python version you want to point to, select it by writing the number corresponding to the version you want to use. To verify this selection, write:

Updating Python on MacOs

Updating Python on MacOs is more straight forward. In MacOs systems you can as well have different Python versions installed at the same time. This makes it simpler to update it by visiting python.org MacOs download page, select the installer to download and run it. If you are more of a Homebrew user, run the following commands:

Once the installation finishes, you’ll have the latest Python version installed which you can verify with the following code:

How to Update Python Version? — [Upgrade Python Version]

Are you looking to update Python version to the latest python version? Then this blog post will guide you with how to upgrade Python version.

List of content you will read in this article:

Python is an open-source high-level programming language that allows users to execute commands, plugins on their machine, and even software from several major suppliers. It means you can operate it on many different operating systems, including the Windows VPS Server. Python is a cross-platform programing language.

Pip is one of the best applications for Python package installation and administration. Pip’s popularity stems from the many apps that use this tool. Pip enables 3rd Party package installed to manage binary packages with the quickly configured package manager. Since Python’s latest releases have piping as normal, this guide will explain how to install PIP and how to update Python version with a complete step-by-step guide.

What is PIP?

PIP is a software management framework for installing and managing Python-written program packages. It is called the ‘preferred software installer’ or ‘Pip Installs Packages.’ PIP, used for Python, is a command-line interface for handling PyPI program installation. You might need to upgrade PIP if you’re using an earlier version of Python on Windows. Download the application file, open the command- line and start the installer to run PIP on Windows quickly. It will teach you how PIP is installed on Windows and how it can be modified, upgraded, and set up.

How to update Python on Windows Operating System?

There are two simple ways to update your current Python version with the latest one. They are as follows:

So let’s see how we can update the Python version with these two methods, one by one.

Method 1: Python update on Windows using the Python Installer

This method of updating the Python version will work if Python is installed or not on your System.

If Python is already installed on your system, you can check it using the python -V command.

Step 1: Download the Python installer from the Official Website of Python

The easiest way to update the Python version is to download the latest version from the official website ( https://www.python.org/downloads/ )

You can click on the Download Python 3.11.0 button, and it will download the latest compatible Python version for your system.

Step 2: Install the Downloaded Python Installer

After downloading the exe file, double-click on it to install Python.

Step 3: Install Python

Now, you can install the latest version of Python.

Check the “Add python.ext to PATH”, then click on the “ Install Now ” button.

This will start the installation process.

After processing, the latest version of Python will be installed on your system.

Click on the “Close” Button.

Step 4: Verify the Update

After successful installation, you can verify whether or not the latest version is installed on your system. To check the version, you can again run the same command, python -V , on the prompt command.

Now, you can see that it is showing the latest installed version, i.e., Python 3.11.0.

Note: If it still shows the old version, you may restart your system . Or uninstall the old version from the control panel .

Method 2: Install Python using Command Line Only using the Chocolatey Package Manager

Chocolatey is a Package Manager command line tool for windows, and we can use it to install software for our window system. In our case, we can use it to install Python or update the current version of Python.

Step 1 Open The Powershell as Administrator

To install Chocolatey, you need to open PowerShell as Administrator.

Step 2: Install the Chocolatey Package Manager Command

Now, you can install the Chocolatey package manager using the following command.

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString(‘https://community.chocolatey.org/install.ps1’))

Step 3: Verify the Chocolatey Installation

Now, you need to check whether Chocolatey has been installed successfully. To check it, run the “ choco ” command.

It is installed successfully because it is showing version Chocolatey v1.2.0.

Step 4: Update Python with Chocolatey

With the help of the choco upgrade command, we can update our current Python version.

Step 5: Verify the Version

You can again check the latest installed Python version using the following command.

Note: The old version of Python will remain on your system. You can uninstall the old version from the control panel.

How To Upgrade Python on macOS?

You can download the latest version of Python for macOS from the official Python website, similar to what you did on windows OS to update Python version on your system. To check whether it is updated to the lasted version or not, follow the below-listed commands to check the Python version.

If you want to execute this new Python release with the python command instead of python3, install an alias in your $HOME directory’s bash profile file.

Open the terminal window and type the following commands:

$ cd $HOME
$ nano .bash_profile

Then, at the bottom, add this segment.

Python 3.9 version can be checked using the following command.

How to Update Python version on LINUX?

Users can use the below listed Linux commands to upgrade Python version on the Linux server:

ppa:deadsnakes/ppa can be added to the system’s Software Sources to upgrade the machine with unsupported packages from this untrusted PPA.

$ sudo add-apt-repository ppa:deadsnakes/ppa

This command is used to update the Python package.

$ sudo apt update
$ sudo apt install python3.9

Then, using the commands below, you can search the versions of your new and current Python installations:

This command will show you the following version of python installed in your system

Как обновить Python в Linux?

Руководство по обновлению Python в операционных системах семейства Linux.

Введение

Представь себе ситуацию, ты придумал какой-нибудь проект, решил реализовать его на Python, открываешь терминал и обнаруживаешь старую версию, например Python 3.4.

Правильно, обновить Python через пакетный менеджер.

Далее я расскажу как это сделать.

Не забываем самое главное.

Все команды необходимо выполнять под пользователем root или же через sudo.

Обновление Python

Рассмотрим несколько примеров обновления Python в самых популярных дистрибутивах

Обновление Python в Debian Linux (Ubuntu, Raspbian, Mint и другие)

В моем случае я буду использовать raspberrypi 4 с дистрибутивом raspbian (основан на Debian buster). Открываем терминал (или подключаемся по ssh) и вводим команду apt update

Видим примерно такую же ситуацию, локальный репозиторий обновил информацию о доступным пакетах из сетевого репозитория и стали доступны обновления других пакетов. Но мы сейчас не об этом. Нас интересует только python.

В моем дистрибутиве используется последняя доступная версия 3.7.3-1

Обновление Python в Red Hat Linux (CentOS и Fedora Linux)

В принципе обновление пакетов в linux имеет схожий алгоритм. Сперва вы получаете список доступных пакетов из удаленного репозитория и сравнивание с тем, что установлено у вас локально. После обновление локального репозитория нужно инициализировать установку python. Разнообразных дистрибутивов linux у меня под рукой нет, да и используя я в серверных вариантах только debian-based. Но информация о работе с другими пакетными менеджерами доступна онлайн:)

Обновление python выполняется одной командой

Заключение

В этом руководстве мы узнали как обновить Python в Linux.
