2 Ways to install latest Python on Windows 11 or 10 – GUI & CMD

Installing Python 3 on Windows 11 or 10 machines is not difficult, however, if you are a beginner then we have discussed the both Graphical and command prompt ways to install it. Especially, for those who are not much familiar with Python, it is an open-source high-level interpreted programming language.

It is known for its versatility because it has been used widely for programming applications, web development, data analysis, machine learning, artificial intelligence, data visualization, web scraping, and scientific computing. The reason behind’s Python popularity among the developer community is its clear syntax, readability, ease of use, and large number of libraries & frameworks. All this is possible because of a vast but active community.

Python also supports most of the popular IDEs or can be written using a simple text file created using Notepad.

Let’s go through the article, whether you are a beginner or experienced, in this tutorial we will find the necessary steps required to install and set up Python on Windows operating systems.

Installing Python 3 on Windows 10 or 11

Here we are discussing two ways to set up Python one is using the graphical installation wizard and the other with the help of a command in prompt or Powershell (Terminal).

1. Download Python’s latest version

As we know Python is not included in Windows by default to compile our programs based on it. Therefore, visit the official website- python.org to download the latest version by clicking on the Download button.

Download Python for windows

2. Start Python Installation on Windows

After following the previous steps, you would already have the executable file of python on your Windows.

  • Double-click python executable to start the installation wizard.
  • Select the “Add Python.exe to PATH” box otherwise, we won’t be able to run PIP or Python using native Windows Powershell or command prompt.
  • After that click on the Install Now option.

Add python.exe to path

  • The setup will start running, this will also install PIP and documentation on your system.

Installing PIP pacakge manager

  • Finish the installation by clicking on the Close button.

Python installaion is done

3. Check version

To confirm, the installation is successful without any error, let’s check the version of installed Python and PIP. For this, you can either use the Command prompt or Powershell. Alternatively, we can also run the Python terminal app to issue commands, for that in your Windows Search type – python as its app appears, and click to open it. You will have a Python interpreter with version details as well.

Note: If typing python on on command terminal or Powershell, opens the Microsoft Store then go through the next step.

Check version

4. Stop Python from opening the Microsoft store

By default, if you type python on the command prompt or PowerShell in Windows, it will open Microsoft Store to download another version of Python instead of using the existing version of your Python. To stop that and tell the system to run the one you have installed, Follow the steps:

Stop Python from opening the Microsoft store

  1. Go to the Windows Search box
  2. Type- Manage App Execution Aliases
  3. As its icon appears click to open it.
  4. Search for Python3 and Python App Installers
  5. Turn off the toggle button given there for them.
  6. Close your CMD Terminal or Powershell and reopen it again.
  7. Now, type python in that to check your current version.

#Use the command line method

5. Open PowerShell, CMD, or Terminal (Admin)

Right-click on the Windows Start button and select Terminal (Admin). If you have PowerShell then you can go for that as well.

Open Windows Terminal

6. List Python versions

When you go for command line installation there are multiple versions available to install. We can use Winget to first check what are those and, later, to install them as well.

winget search Python.Python

winget command to search python

7. Use Winget to install Python

Once you have decided which version is suitable for your project then set it up using the following syntax.

winget install Python.Python.version-number

For example, if you want to have 3.11 then the command will be like this:

winget install Python.Python.3.11

When you are done with it, close your CMD terminal or PowerShell and reopen it again to check, whether it is working or not.

For that either use:

8. Run a simple program

Open the Python command line and type:

print ('Hey I am here with Python')

The above code will print “Hey I am here with Python” on your screen.

Windows set python version

На одной рабочей машине одновременно может быть установлено несколько версий Python. Это бывает полезно, когда идет работа с некоторыми внешними библиотеками, которые поддерживают разные версии python, либо в силу каких-то других причин нам надо использовать несколько разных версий. Например, на момент написания статьи последней и актуальной является версия Python 3.11 . Но, допустим, необходимо также установить версию 3.10 , как в этом случае управлять отдельными версиями Python?

Windows

На странице загрузок https://www.python.org/downloads/ мы можем найти ссылку на нужную версию:

Управление несколькими версиями Python

И также загрузить ее и установить:

Установка разных версий Python на Windows

Чтобы при использовании интерпретатора Python не прописывать к нему весь путь, добавим при установке его в переменные среды. Но здесь надо учитывать, что в переменных среды может содержаться несколько путей к разным интерпретаторам Python:

Установка разных версий Python на Windows в переменные среды

Та версия Python, которая находится выше, будет версией по умолчанию. С помощью кнопки «Вверх» можно нужную нам версию переместить в начало, сделав версией по умолчанию. Например, в моем случае это версия 3.11. Соответственно, если я введу в терминале команду

python --version

или

py --version

то консоль отобразит версию 3.11:

C:\python>python --version Python 3.11.0

Для обращения к версии 3.10 (и всем другим версиям) необходимо использовать указывать номер версии:

C:\python>py -3.10 --version Python 3.10.9

например, выполнение скрипта hello.py с помощью версии 3.10:

Подобным образом можно вызывать и другие версии Python.

MacOS

На MacOS можно установить разные версии, например, загрузив с официального сайта пакет установщика для определенной версии.

Для обращения к определенной версии Python на MacOS указываем явным образом подверсию в формате python3.[номер_подверсии] . Например, у меня установлена версия Python 3.10. Проверим ее версию:

Аналогично обращении к версии python3.9 (при условии если она установлена)

К примеру выполнение скрипта hello.py с помощью версии python 3.10:

Linux

На Linux также можно установить одновременно несколько версий Python. Например, установка версий 3.10 и 3.11:

sudo apt-get install python3.10 sudo apt-get install python3.11

Одна из версий является версий по умолчанию. И для обращения к ней достаточно прописать python3 , например, проверим версию по умолчанию:

Для обращения к другим версиям надо указывать подверсию:

python3.10 --version python3.11 --version

Например, выполнение скрипта hello с помощью версии Python 3.10:

Но может сложиться ситуация, когда нам надо изменить версию по умолчанию. В этом случае применяется команда update-alternatives для связывания определенной версии Python с командой python3. Например, мы хотим установить в качестве версии по умолчанию Python 3.11. В этом случае последовательно выполним следующие команды:

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.10 1 sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.11 2

Числа справа указывают на приоритет/состояние. Так, для версии 3.11 указан больший приоритет, поэтому при обращении к python3 будет использоваться именно версия 3.11 (в моем случае это Python 3.11.0rc1)

Управление версиями Python в linux

sudo update-alternatives --config python3

можно изменить версию по умолчанию

Set Python 3 as your default “Python Version” on Windows 10/11

Python is a well-known programming language when it comes to solving Data Science related problems. It helps in easing down the work of Data Science with the help of its fast execution of codes because of its built Object-Oriented Programming but, there is a problem with this language as well.

Many Pythonists find it difficult to access the correct Python version because of too many Python versions present in their computer system. Due to this, they face problems in downloading the necessary packages in the correct Python version they want.

This leads to many problems in code executions as well as creates confusion for the computer to throw which version at what time.

Now, the question arises of how to resolve this issue and how to add the desired Python version say 3 as the default version on Windows 7/10/11.

The answer to this question is simple and given below. Just make sure that you have 2 or more 2 Python versions downloaded in the system to follow these steps of fixing the issue.

Steps to Change the Default Python Version on Windows 10/11 to Python 3

  • Open your command prompt and check the current Python version the system is using. This will help you get to know which version you are using right now and with which version you want to replace the same.
  • python --version

Check Default Python Version on Windows 10 using command prompt

  • After checking the Python version find the path of your Python versions that will be present most probably in C Drive under the Program Files folder.
  • Open the Program Files folder and locate your Python versions. After locating the same click on the versions and copy the path of the scripts folder of all the Python versions installed.

Find Installed Python folderSelect Pyhton 3 Scripts folder

  • Also, copy the path of the Program Files being present in C Drive.
  • Once the paths are copied the next step is to locate your Environment Variables for the computer. This can be done by right-clicking on the “This PC” option of your computer and clicking on the Properties option. After clicking on the same click on Advanced System Settings under the Properties option.
  • Once done, a pop will come on the screen displaying various options out of which you need to click on the Environment Variables option. The Environment Variables will open up for you and you can see all the system variables present there.

Environment Variables option to change the Windows 10 or 7 Python version

  • The Environment Variablsegregatedgintendednto two different parts that are User Variables and System Variables. Just locate the Path option under the System Variables and click on the same.
  • After clicking on the Path option make sure to put the Scripts and Program Files path of different Python versions that you currently want to use and work in, and where you want to store all your necessary packages should be put first followed by others. Simply, click on the Browse button and select the path of the Script folder and the Python3 itself.
  • Note:Remove any other Python Version available in the System variables, for example, Python2. Select its path and click on the Delete button.
  • Press the OK button to save the changes in the Windowgovernmentalentaltal Variables.

Add Python 3 directory path in Windows 10 or 7

  • Once this is done, restart your Command prompt and again type python --version . Now you will find the desired version there on the system and ready to be usable by the coder.

Conclusion

This is how a user can get his/her Python version when there are multiple versions on the computer. Try this out and start coding with your desired version.
