Change python version on per user basis To change a python version on per user basis you simply create an alias within user's home directory. Open ~/.bashrc file and add new alias to change your default python executable: alias python='/usr/bin/python3.4 In ubuntu By default python version was 2.7. We need to use python3 to run the python files with the latest version. Steps to change the default python version to 3. Check the current version . #python --version. Python 2.7.17. Execute this command to switch to python 3.6. #sudo update-alternatives --install /usr/bin/python python /usr/bin.
Now you can change the default version of Python using the following command: sudo update-alternatives --config python There are 3 choices for the alternative python (providing /usr/bin/python) ls /usr/bin/python. Now, set your version priorities by issuing the following commands: update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1. update-alternatives --install /usr/bin/python python /usr/bin/python3.8 2. You can then list the python priorities by: update-alternatives --config python. Finally, check your default.
This can be done from your linux terminal with the following steps:Check python version on terminal - python --version Get root user privileges. On terminal type - sudo su Write down the root user passwor To switch to another Python version, all you need to do is execute the command on Step 4 and select the other option. In this case, we would choose option 2 to use Python 3. Method 2: Old-school way without configuration This other method, we would refer to it as the manual way since we won't perform any configurations Instead of retrieving the python version from the linux command line we can ask directly the python interpreter to perform version check. Python 2 $ python Python 2.7.15rc1 (default, Apr 15 2018, 21:51:34) [GCC 7.3.0] on linux2 Type help, copyright, credits or license for more information
