How To Install Python 3 and Set Up a Local Programming Environment on Ubuntu 16.04

In this tutorial, we will guide you through the process of installing Python 3 and setting up a local programming environment on Ubuntu 16.04.

Step 1: Update the Package Manager

Before we start, let's make sure that the package manager is up-to-date. Open up the terminal and type in the following command:

sudo apt-get update

Step 2: Install Python 3

To install Python 3, type in the following command:

sudo apt-get install python3

You can verify that Python 3 has been installed by running the following command:

python3 --version

This should output the version number of Python 3 that you just installed.

Step 3: Set Up a Local Programming Environment

To set up a local programming environment, we will be using a package called virtualenv. Virtualenv allows you to create isolated Python environments, which is useful when you need to work on different projects with different dependencies.

To install virtualenv, type in the following command:

sudo apt-get install virtualenv

Once virtualenv is installed, you can create a new virtual environment by typing in the following command:

virtualenv myenv

This will create a new virtual environment in a folder called "myenv". To activate the virtual environment, type in the following command:

source myenv/bin/activate

You should see that the terminal prompt has changed to indicate that you are now working within the virtual environment.

Step 4: Install Packages

Now that we have our virtual environment set up, we can install any packages that we need for our project. For example, if we wanted to install the numpy package, we would type in the following command:

pip install numpy

pip is the package installer for Python, and it will install the numpy package and any dependencies that it requires.

Step 5: Deactivate the Virtual Environment

When you are finished working within the virtual environment, you can deactivate it by typing in the following command:

deactivate

This will return you to your normal shell environment.

Conclusion

By following the steps in this tutorial, you should now have Python 3 installed and a local programming environment set up on your Ubuntu 16.04 machine. Happy coding!
