Python has become an essential programming language for developers, data scientists, and anyone involved in technology. With its vast libraries and frameworks, it is widely used for web development, data analysis, artificial intelligence, and more. If you’re using Ubuntu Linux and want to harness the power of the latest Python version, you’re in the right place. This guide will walk you through the straightforward process of installing Python on your Ubuntu system. Whether you are a seasoned programmer or a beginner, this step-by-step approach will ensure you have the most up-to-date version of Python ready to use.
Updating Package Lists
Before installing any new software, it’s essential to update your package lists. This ensures that you get the latest version available from the repositories. You can do this by running a simple command in your terminal.
Installing Prerequisites
To compile and install Python from source, you need to install some essential packages. These packages include build-essential, libssl-dev, and others that are necessary for building Python.
Downloading Python Source Code
Once you have your prerequisites installed, the next step is to download the latest Python source code. You can find the latest version on the official Python website. Use wget or curl to download the tarball directly to your system.
Extracting the Source Code
After downloading the Python tarball, you need to extract it. This can be done easily using the tar command. Extracting the files will create a new directory with the Python source code.
Configuring the Build
Before compiling Python, you need to configure the build options. This step allows you to customize the installation according to your needs. You can specify options like installation path and enable certain features.
Building and Installing Python
With the configuration done, you can now compile the Python source code. This process may take some time, depending on your system’s performance. After the build process is complete, you can install Python using the make install command.
Verifying the Installation
Once the installation is complete, it’s crucial to verify that Python is installed correctly. You can check the version of Python installed by using the python3 –version command in the terminal.
