It makes sense that as time passes by, a utility or programming language progresses in terms of features and performance. Now that we have covered the meat of the matter let’s talk about which Python version you should get and why.
UBUNTU PYTHON 3 INSTALL INSTALL
Why you should install Python 3.5 or later You can do the same for any particular version of your choice. Once it’s done, you can check whether the installation was successful or not by simply running the commands we mentioned at the start.Īs you can tell from the image, we have successfully downgraded from Python 3.8.5 to Python 2.7.12.

Note: In the below command we are not using standard installation command to install program from source i.e make install, becuase it will override your default pre-installed python version. Finally, Install Python from compiled source Thus the final command will be: make -j 2Ģ is the number of core we have on our system.
UBUNTU PYTHON 3 INSTALL PC
For that first, you should know about your PC cores. To compile python you can use the command make, however, to do it as per your computer CPU core resources, we use the flag -j with it. Note: –enable-optimizations option will optimize the Python for your system. Navigate to the folder and run configure scriptĪfter extracting your downloaded Python folder, first, switch to that directory for thatĪs you inside the directory, run the Configure script to check all the required dependencies before finally compiling the source. Use the below command to extract tarball file: X.x.x will be the version as in our case it was 3.4.0, thus our filename was Python-3.4.0.tar.xz Right click on the Python Tarball file given on the website and copy the link and after that use it with wget in your terminal:įor example, we have copied the link of Python 3.4 tarball file… wget Extract Tarball FileĪnd then see the name of the downloaded file, it will be like this Python-x.x.x.tar.zx

To install any previous Python version such as Python 2.3 – Python 2.6, Python 3.1 – Python3.4, Python 3.6 – Python3.7… We can simply use Deadsnake repository, here is the command for that: sudo add-apt-repository ppa:deadsnakes/ppaĪfter adding the repo use Python installation command along with the version you want to install, for example: sudo apt-get install python3.4 Switch between multiple Python versions If you don’t have the latest version on your Ubuntu 19.04 i.e Python3 then use the below command to install: sudo apt install python3įor those want to install some previous version of Python on their Ubuntu Linux OS they can use the below commands:įor Python 2.7.x version sudo apt install pythonįor Python minimal version of 2.7 sudo apt install python-minimal Use Apt repository to install Python
