Install Python 3 in Ubuntu (Linux based)

In this video, we will learn how to install Python 3 on Ubuntu Desktop Operating system, using two most popular methods. In the first method, we will use Ubuntu's default package manager called "APT" to download and install from a Package repository. This method is preferred to setup Python, on a development machine. In the second method, we will download the source files from PSF's python.org, compile them and build binaries. This method is preferred to setup Python on a secure and critical environment, like Production Server. Now there are two ways to proceed from here. You can just pick a method & use the commands provided below. Just copy, paste and run them in your terminal one by one, and you will have a working setup on your system. You can do this, if you have some basic understanding about how Linux based systems work. But if you new to the Linux world, then I strongly recommend you to go through the full video. Because we will touch and discuss lot of things in there while giving you a rundown of all the commands used in the process. We will learn about APT package manager, repositories (repos), environment variables, executables and lot more. I am hoping it would be worth investing your valuable time going through the full video. Method 1 : Install Python 3 using APT package manager (From PPA) i. Update the system's local repo list sudo apt update ii. Install a pre-requisite package called "software-properties-common" sudo apt install software-properties-common iii. Add deadsnakes PPA to the system's repository list sudo add-apt-repository ppa:deadsnakes/ppa iv. Again update the system's local repo list sudo apt update v. Install latest patch version of Python 3.10 sudo apt install python3.10 vi. To verify installation of Python 3 python3.10 --version Method 2 : Install Python 3 from source files ( From PSF's python.org) i. Update the system's local repo list sudo apt update ii. Install supporting softwares (packages) sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev wget iii. Create a directory mkdir /tmp/python cd /tmp/python iv. Download the Latest Version of Python Source Code wget https://www.python.org/ftp/python/3.1... v. Extract compressed files tar -xvf Python-3.10.5.tgz vi. Configure & Optimize Python for building ./configure --enable-optimizations vii. Build Python binaries make -j 8 viii. To install as a second instance of Python sudo make altinstall ix. Verify Python Version python3.10 --version Python Specific commands : 1. To check version of Python : python3 --version 2. To enter into the Interactive mode (REPL) of Python : python3 3. To quit from the Python terminal : quit() exit() Keyboard shortcut : Ctrl + Z Basic Linux/Unix commands : 1. To clear the terminal clear 2. To create a new directory : mkdir directory-name 3. To change working directory : cd directory-path 4. To print out the value stored in a variable like PATH : echo $PATH 5. To create an alias to an executable : alias alias-name=exe-file-name 6. To check the location (directory) in which an executable is located : which exe-name type exe-name 7. To open up the terminal : Shortcut : Ctrl + Alt + t
