NOTE: These commands will display the Python version installed on your Linux system.

Check Python Version Using Interactive Shell

Python’s interactive shell is another way to find Python version. Open your terminal and enter one of the following commands:

For Python 2:

python

For Python 3:

python3

Once you are in the Python interactive shell, you can get Python version with the following Python commands:

import sys
print(sys.version)

Check Python Version Using Package Managers

If you installed Python using a package manager, you can use these tools to check the Python version.

For Debian-based systems, such as Ubuntu, you can use `apt`:

apt show python3

Check Python Version Using Package Managers

For Red Hat-based systems, like CentOS, you can use yum:

yum info python3

NOTE: These commands will provide detailed information about the Python version installed on your system.

Finding Python Version by Checking the Path

We can also determine the path to the Python interpreter and indirectly obtain information about the installed version using the `which` command:

which python3

This command will return the path to the Python interpreter. We can then use this path to check the version:

/path/to/python –version

Replace ‘/path/to/python’ with the actual path obtained from the previous which command.

Очень важно знать, какая версия Python установлена на вашем компьютере, особенно если вы работаете над проектом, который требует определенной версии.

Очень важно знать, какая версия Python установлена на вашем компьютере, особенно если вы работаете над проектом, который требует определенной версии. Версия Python может влиять на работу кода, так как разные версии могут иметь различные функции и библиотеки. Например, у вас может быть установлена версия Python 2.7, но вы хотите использовать функции, доступные только в Python 3.6. В этом случае вам нужно будет обновить Python до версии 3.6.

Освойте Python на курсе от Skypro. Вас ждут 400 часов обучения и практики (достаточно десяти часов в неделю), подготовка проектов для портфолио, индивидуальная проверка домашних заданий и помощь опытных наставников. Получится, даже если у вас нет опыта в IT.

Узнайте свою версию Python

Есть несколько способов узнать версию Python на вашем компьютере. Но самый простой и надежный из них — это использовать командную строку.

Для пользователей Windows

Откройте командную строку, нажав клавиши Windows + R, затем введите cmd и нажмите Enter.

В командной строке введите python --version и нажмите Enter. Система должна показать версию Python, установленную на вашем компьютере.

Для пользователей MacOS и Linux

Откройте Терминал.

В терминале введите python3 --version и нажмите Enter. Система должна показать версию Python, установленную на вашем компьютере.

На курсе Skypro «Python-разработчик» освоите основные инструменты программирования, получите опыт на реальных проектах и сможете стартовать в профессии уверенным новичком. Преподаватели — практикующие программисты с большим опытом, а в центре карьеры помогут составить цепляющее резюме и подготовиться к собеседованию.

Обновление Python

Если вы хотите обновить свою версию Python, вы можете скачать последнюю версию с официального сайта Python. Помните, что обновление Python может повлиять на некоторые из ваших существующих проектов, которые зависят от старых версий Python. Поэтому всегда рекомендуется создать резервную копию ваших проектов перед обновлением Python.

В любом случае, знание версии Python на вашем компьютере поможет вам писать более эффективный код и избегать проблем совместимости.

Python is a versatile and widely used programming language that has become an essential tool for developers, data scientists, and researchers. With its simplicity, flexibility, and extensive libraries, Python has become the language of choice for various applications, from web development and data analysis to artificial intelligence and machine learning. 

Knowing the version of Python installed on your system is crucial for various reasons. It helps ensure compatibility with libraries, frameworks, and third-party packages you might want to use in your projects. Additionally, some Python features and syntax may differ across versions, so being aware of the installed version can prevent potential issues and ensure smooth development. In this article, we’ll explore multiple methods to check the Python version on both Linux and Windows operating systems.

In this article, we’ll provide a comprehensive guide on how to check Python version in Linux and Windows operating systems. We’ll cover the different methods, including command-line instructions, and provide troubleshooting tips to help you overcome common issues.

Why Check the Python Version?

Before diving into the methods of checking Python versions, it’s essential to understand why it’s crucial to know the version of Python installed on your system. Here are a few reasons:

Compatibility

Different Python versions have varying levels of compatibility with libraries, frameworks, and third-party packages. Knowing the Python version ensures that you can use the required packages and libraries without compatibility issues.

Syntax Differences 

Python syntax and features change across versions. For example, Python 2.x uses the print statement, while Python 3.x uses the print() function. Being aware of the installed version helps you write code that’s compatible with your Python version.

Deprecation and Removal of Features 

As Python evolves, some features and modules are deprecated or removed. Knowing the Python version helps you avoid using deprecated features and plan for future updates.

Checking Python Version in Linux

Method 1: Using the Command Prompt

Linux is a popular operating system among developers. If you install Python in Ubuntu Linux, To check the Python version in Linux, you can use the following command:

python3  --version

The output will display the Python version and any additional information, such as the build number or compilation date. If the command returns an error indicating that Python is not installed or recognized, you may need to install or update your Python installation.

Method 2: Using the Python Interpreter

Another method to see Python version is by launching the Python interpreter. Open your terminal and enter:

python3

Once the interpreter is running, Type the following command for Python version check:

import sys
print(sys.version)

This will print the complete version information, including the build number, compiler details, and other relevant information.

To exit the Python interpreter, simply type exit() and press Enter.

While this method provides more detailed version information, it requires launching the Python interpreter, which may not be desirable in certain situations.

Method 1: Using the Command Prompt

If you install Python in Windows, you can find Python version in Windows using the command prompt. Open the Command Prompt cmd.exe and enter the Python version command:

python  --version

This will display the complete version information, including the build number, compiler details, and other relevant information.

To exit the Python interpreter, type exit() and press Enter.

Troubleshooting Common Issues

When checking the Python version, you may encounter some common issues. Here are some troubleshooting tips to help you overcome them:

Python not Recognized: 

If the command python –version returns an error indicating that Python is not recognized, check if Python is installed correctly and added to the system’s PATH environment variable.

Multiple Python Versions Installed 

If you have multiple Python versions installed, you may need to specify the version you want to check. For example, if you have both Python 3.8 and Python 3.9 installed, you can check the version of Python 3.9 using the command python3.9 –version.

Python version not displayed: If the command python –version does not display the version information, try using the python -V command instead. This will display the version information in a more verbose format.

Best Practices for Managing Multiple Python Versions

If you work with multiple Python projects or environments, you may need to manage multiple Python versions on your system. Here are some best practices to help you manage multiple Python versions:

Use Virtual Environments: 

Virtual environments allow you to create isolated Python environments for each project, which helps to avoid version conflicts and ensures that each project uses the correct Python version.

Use Version Managers: 

Version managers like pyenv or conda allow you to easily install and manage multiple Python versions on your system.

Keep your Python Versions Up-to-Date: 

Regularly update your Python versions to ensure you have the latest security patches and features.

Conclusion
