![]() ![]() With python -version, we will get pyhton2.7. ![]() Press to keep the current choice, or type selection number:1 There are 2 choices for the alternative python (providing /usr/ local/bin/python). We then need to specify the number referring to the python version we want, e.g., number one for python2.7. Instead, we use sudo update-alternatives -config python If we want to change the python version again, we don't have to configure it like the above ones. So if we type python -version then we will get python3.11. This guide aims to provide a comprehensive walkthrough on how to install Python 3.7 on Ubuntu 22.04 Jammy Jellyfish LTS or its older stable release of Ubuntu 20.04 Focal Fossa LTS. The alternative with the highest priority (the last part of each command above) will be the default. Python 3.7 remains popular among developers for its reliability and robust feature set, even as newer versions have become available. Sudo update-alternatives -install /usr/ local/bin/python python /usr/bin/python2.7 1 For this, we use the sys module, which has the version and versioninfo. If you automate stuff with Python, sometimes you will need to check the Python version in a Python script. To check the Python version, Open the command line interface and execute the following command: python3 -V. sudo update-alternatives -install /usr/ local/bin/python python /usr/bin/python3.11 2 Therefore, Ubuntu Linux comes with Python preinstalled. We use the update-alternatives command as follows. ![]() You’ll output this to a file called anaconda.sh for quicker use. So run the following command with this goal: ls /usr/bin/python. The ls command helps you check binary Python executable files in Debian and Ubuntu. The first step is to find out what versions of Python are available on your Debian/Ubuntu system. Use curl to download the link that you copied from the Anaconda website. Step 1: Checking the available versions of Python in Debian/Ubuntu. This is a good directory to download ephemeral items, like the Anaconda bash script, which you won’t need after running it. Now, we want python3.11 to be the default python version. Next, change to the /tmp directory on your server. From progmatico, its not recommended that you uninstall builtins on Ubuntu such as Python. at 17:44 Michael i dont like to left things that im not using anymore installed on my machine rofl. rwxr-xr-x 1 root root 7163864 Dec 7 10:11 /usr/bin/python3.11 If you need another version of python, just install it and leave 3.8 in case you need it for something else. You may get something like this: lrwxrwxrwx 1 root root 9 /usr/bin/python2 -> python2.7 In that case, you can change the default version using the update-alternatives command.įirst, let's check the python versions we have installed using ls -la /usr/bin/python* If you type python -version or python3 -version, you may get the python version you do not expect. In Ubuntu (and in some other OSes), it is possible to have multiple versions of pythons, e.g, python2.7, python3.10, python3.11. I make this short note for myself because I often change or have to deal with new OS such as Ubuntu. ![]()
