And provides us with the opportunity to become more familiar with Python if you aren’t already. If you use Python 3 on your machine outside of an environment, you will need to use the python3 and pip3 commands exclusively. Important: Within the virtual environment, you can use the command python instead of python3, and pip instead of pip3 if you would prefer. When you see this prefix, it means that the environment my_env is currently active and creates programs where they will use only this particular environment’s settings and packages. And the name of your environment in parentheses should be the first thing you see on your line: (my_env) :~/ environments our prefix may appear somewhat differently, depending on what version of Debian Linux you are running. Now, your command prompt will be prefixed with the name of your environment now. By typing the command below it would be achieved. You need to activate it to use this environment. Output bin include lib lib64 pyvenv.cfg share Since, pyvenv sets up a new directory that contains a few items, which you can view this by using the following command: ls my_env You can create an environment when you are in the directory where you would like the environments to live.

Let’s either choose which directory we would like to put our Python programming environments in, or create a new directory with mkdir, as in: mkdir environments cd environments You are learning How to install Python 3 on Ubuntu 20.04

To install venv: sudo apt install -y python3-venvĪfter that, you are ready to create environments. While there are a few ways to achieve a programming environment in Python, we’ll be using the venv module here, which is part of the standard Python 3 library. Each environment is basically a directory or folder on your server that has a few scripts in it to make it act as an environment. Therefore, you can set up as many Python programming environments as you would like. Setting up a programming environment provides greater control over Python projects and over how different versions of packages are handled, which is especially important when working with third-party packages. In this step, we want to explain that Virtual environments enable you to have an isolated space on your server for Python projects, ensuring that each of your projects can have its own set of dependencies that won’t disrupt any of your other projects. However, there are a few more packages and development tools to install to ensure that we have a robust set up for our programming environment: sudo apt install -y build-essential libssl-dev libffi-dev python3-dev In case you want to install NumPy, you can do so with the command pip3 install numpy. Then, you can use the package_name to refer to any Python package or library, such as Django for web development or NumPy for scientific computing. You can install Python packages, using the following command: pip3 install package_name

Also, you can install pip, to manage software packages for is a tool that will install and manage programming packages we may want to use in our development projects.
