11/26/2023 0 Comments Multiple python versions linux![]() ![]() In my case int was installed in /Users/ashiskb/.pyenv/versions/3.7.13. Please note the path where it was installed. I assume the specific version of python install was successful in the previous step.Yay!! The command I then executed in the terminal was the following: If you can find the latest 3.7.x there, go for it.Be sure to run the following command to list what versions of Python you could install in your system currently using pyenv. Now use pyenv to install specific python version or update your python version. Assuming the installation of pyenv was a success in the previous step.However, if you do not have brew/ homebrew in your system already, please follow the simple step mentioned here. To install pyenv run brew install pyenv at the terminal.Please use package called pyenv that will help you switch between different versions of Python (in case you need to run Python 2.x for some reason, and in anticipation of Python 4.0 coming). Please understand the steps may need to be changed based on your current system configurations – lots of unknown do exist when I was writing this blog post. In this case, it’s a good idea to have the specific python interpreter version and a virtual environment using that specific interpreter setup in your own workstation. Say, someone told you to work on a python project build on python 3.7.x and gave you all the project files, and a requirements.txt file listing package versions used. The below code shows a simple use of the sys.version to check the version.Setting up multiple python versions and virtual environments in Mac, Windows, Ubuntu 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. The python micro and minor releases are somewhat compatible, and a new version can run the same code without much problem. ![]() MICRO: The python micro releases contains many bug fixes and improvements.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. This tutorial will see how to check the python version running on your Linux system. ![]()
