The below code shows a simple use of the sys.version to check the version. The second one uses the sys.version_info, which contains a tuple containing some python version info. The first uses the sys.version string, which contains some details like the python version, compiler version, etc. To get the version number using the sys library, we have two methods. These libraries are present in the python standard library, so we have no installation problem for these libraries. In this tutorial, we were using the sys and platform library. We have many modules that can help us to get the version of python. If f-string is supported, then continue with the code else, run some other code block. We can improve the program by checking the python version used programmatically and using the if/else condition to check whether f-strings are supported by the version. F-strings have been included in python in the 3.6 release, and so the code will work only on python version 3.6 or later. For example, assume you have written a python code that used f-strings for formatting strings. This technique has a benefit if our python program can be run only in a specified version. We can also use a python script to check which python version is used to run the script. If we write software using Python2, it will have some problems while running using the python3 interpreter.Ĭhecking python version in command line using –version parameter Using Python Script Still, the major releases were not compatible with each other. This will allow you to run various Python programs including legacy scripts. The python micro and minor releases are somewhat compatible, and a new version can run the same code without much problem. In this tutorial, you will see how to install multiple versions of python, and change the python version on Debian using the update-alternatives python command. Note that Python 2 support is only available with Enterprise tier licensing. Python developers can see the full list of Python 2 CVE’s we’ve fixed here. MICRO: The python micro releases contains many bug fixes and improvements. As part of ActiveState’s Python 2 extended support, we continuously evaluate and fix known CVE’s impacting Python 2.For example, python 3.7.x, python 3.8.x, etc. MINOR: These releases are bringing new functions, classes, features, etc. For example, python 3 has some subversions like 3.8.3, 3.4.5, etc. MAJOR: The Python programming language has two major releases that are not fully compatible with each other.The below list shows some more details about them. įor example, In Python Version 3.8.6, 3 is the major release(also known as python3), 8 is the minor release number, and 6 is the micro release number. The production-ready releases follow the below-shown syntax for versioning. The Python versioning contains three numbers to identify each release uniquely. Python uses the semantic versioning technique to give a version to its new release. Many Linux systems also have multiple Python versions installed we will also see how to know which versions are installed and how to use a particular version. If you don't have environment variable setup, and you type 'python' in VSCode terminal, it'll point to C:\Users\YourName\AppData\Local\Microsoft\WindowsApps\python.exe, which just opens up python link in Windows AppStore □.This tutorial will see how to check the python version running on your Linux system. So in Windows 10 when you type "python" in CMD Line, it should be the same version as VSCode terminal.įor sanity purposes you should make sure that both "Python: Select Interpreter" and the system environment variables point to the same version of Python.īonus goodie in Windows 10. Terminal in VSCode in general pertains to your default terminal I think. a pip that belongs to Python 3.8, or a pip that belongs to Python 3.9. This will also affect which pip you use, i.e. Just make sure you change Environment variables C:\Users\YourName\AppData\Local\Programs\Python\Python# and C:\Users\YourName\AppData\Local\Programs\Python\Python#\Scripts accordingly. In Windows 10 you can choose to have several Python versions, usually under C:\Users\YourName\AppData\Local\Programs\Python\Python#.
