This document describes how to install Python 3.6 or 3.8 on Ubuntu Linux machines.
To see which version of Python 3 you have installed, open a command prompt and run
If you are using Ubuntu 16.10 or newer, then you can easily install Python 3.6 with the following commands:
$ sudo apt-get update $ sudo apt-get install python3.6
If you’re using another version of Ubuntu [e.g. the latest LTS release] or you want to use a more current Python, we recommend using the deadsnakes PPA to install Python 3.8:
$ sudo apt-get install software-properties-common $ sudo add-apt-repository ppa:deadsnakes/ppa $ sudo apt-get update $ sudo apt-get install python3.8
If you are using other Linux distribution, chances are you already have Python 3 pre-installed as well. If not, use your distribution’s package manager. For example on Fedora, you would use dnf:
$ sudo dnf install python3
Note that if the version of the python3
package is not recent enough for you, there may be ways of installing more recent versions as well, depending on you distribution. For example installing the python3.9
package on Fedora 32 to get Python 3.9. If you are a Fedora user, you might want to read about
multiple Python versions available in Fedora.
Working with Python 3¶
At this point, you may have system Python 2.7 available as well.
This might launch the Python 2 interpreter.
This will always launch the Python 3 interpreter.
Pipenv & Virtual Environments¶
The next step is to install Pipenv, so you can install dependencies and manage virtual environments.
A Virtual Environment is a tool to keep the dependencies required by different projects in separate places, by creating virtual Python environments for them. It solves the “Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keeps your global site-packages directory clean and manageable.
For example, you can work on a project which requires Django 1.10 while also maintaining a project which requires Django 1.8.
So, onward! To the Pipenv & Virtual Environments docs!

This package is a dependency package, which depends on Debian’s default Python 3 version [currently v3.9].
There are three ways to install python3
on Kali Linux . We can use apt-get
, apt
and aptitude
. In the following sections we will describe each method. You can choose one of them.
Install python3 Using apt-get
Update apt database with apt-get
using the following
command.
After updating apt database, We can install python3
using apt-get
by running the following command:
sudo apt-get -y install python3
Install python3 Using apt
Update apt database with apt
using the following command.
After updating apt database, We can install python3
using apt
by running the following command:
sudo apt -y install python3
Install python3 Using aptitude
If you want to follow
this method, you might need to install aptitude first since aptitude is usually not installed by default on Kali Linux. Update apt database with aptitude
using the following command.
After updating apt database, We can install python3
using aptitude
by running the following command:
sudo aptitude -y install python3
How To Uninstall python3 on Kali Linux
To uninstall only the
python3
package we can use the following command:
sudo apt-get remove python3
Uninstall python3 And Its Dependencies
To uninstall python3
and its dependencies that are no longer needed by Kali Linux, we can use the command below:
sudo apt-get -y autoremove python3
Remove python3 Configurations and Data
To remove python3
configuration and data from Kali Linux we can use the following command:
sudo apt-get -y purge python3
Remove python3 configuration, data, and all of its dependencies
We can use the following command to remove python3
configurations, data and all of its dependencies, we can use the following command:
sudo apt-get -y autoremove --purge python3
