How To Install Python on Kali Linux (2022 Guide)

Follow this step-by-step guide to Install or Update Python on your favorite hacking distro, Kali Linux!


How To Install Python on Kali Linux

Kali Linux is a secure distribution of Linux which has been derived from Debian and designed especially for system forensics, hacking and advanced penetration testing. It was developed through the rewriting of BackTrack which is now discontinued. It carries different tools which are designed for different information security tasks like testing, penetration, security research, reverse engineering and computer forensics. This article covers all the steps on how to Install Python on Kali Linux.

If you have Python 3.9, 3.8 or 3.7 already installed, we also show you how to upgrade Python on Kali Linux if you want to go to Python 3.10.

Why Install and use Python on Kali Linux

Kali Linux is an operating system specifically developed for ethical hackers. It is used by thousands of hackers and companies around the world to penetration test and breaks into their networks. It is popular among such audiences due to the various hacking tools it comes packaged with such as Wireshark and Nmap.

This is a bold distribution that has to be disproven. It has more than 580 pre-installed penetration-testing apps in order to discover. Every program comes with its unique flexibility and uses case.

Python is used a lot of scripting and automation and it has various libraries that work with Linux. Hence why many security professionals use Python to create scripts used for hacking purposes that they may create based on a vulnerability.

Below are four different categories of the security professional where Python is used:

  1. Black hat hackers use Python to discover and exploit vulnerabilities, it comes with many network, malware analysis and security libraries that can be utilized by them to compromise an individual or organization. They can also download such applications off the shelf to use to get into a server or device.
  2. Forensic engineers, propose a forensic mode through which they can perform data discovery and recovery in some instances. Python has a famous imaging library called “PIL” which stands for “Python Imaging Library” which is used in AI/ML imaging applications.
  3. Security administrators or IT admins are responsible to safeguard both the information and data of their institution so doing this involves running security tests. What they do is use ready-made and custom Python scripts to review the environment and make sure that there are no vulnerabilities that are discovered easily. Many have automated scripts that they run for example to check for missing patches, open ports and out-of-date software.
  4. Penetration testers working independently or for bug bounty programs use Kali to perform monitoring and social engineering on businesses. They can check for vulnerabilities, default admin accounts, backups that are not encrypted and passwords, and pages open to the public that shouldn’t be!

Let’s get started…

How to Install or Upgrade Python on Kali Linux (Python 3.9, 3.8, 3.7)

One of the widely used high-level and object-oriented languages has become famous for beginners and experienced programmers for being simple and open-source for a big community. With this, you can build all kinds of apps, from small, simple scripts to complex machine learning-based issues.

Version 3.7 which is old can be installed by using the apt package manager directly. Python 3.9 which is stable has been launched with improvements and security updates. The company has added different new modules and extended the existing modules with extra features.

A gentle reminder, Python 3.9 can’t be installed from standard Kali Linux repositories but can be installed from the original source once you add it.

Let’s see how to install Python 3.9 on Kali Linux from the terminal. All the commands shall be implemented in the Kali terminal so it is the same for you. So, you need to open the terminal app by clicking Ctrl + Alt + t from the keyboard in Kali.

Step 1: Install necessary packages in Kali core:

You first need to install all the packages and dependencies which are needed to build the source of python, so, to install the required packages follow the command below:

Python Packages for Kali Linux

[email protected]:~#sudo apt update 

Now you need to upgrade Python on Kali Linux:

Upgrade Python on Kali Linux

[email protected]:~#sudo apt updgrade

Step 2: Download the latest Python release for Kali Linux:

You need to have the latest python release from the python download page, for this you need to use the “curl” command to download the python release or alternatively the way shown in the image:

[email protected]:~#curl

Step 3: Extract the installer file

Once the process of download has been completed, the file shall be saved into the tar extension. Extract the file by using the command below with Tar or you can use alternatives such as p7zip.

[email protected]:~#7za l Python-3.9.tgz

You need to navigate to the following directory of Python

[email protected]:~#cd /home/paul/Python-3.9.1

By executing this, run the following configuration script in order to prepare your system for Python source code compilation

[email protected]:~#./configure –enable-optimizations

If you have issues running it, please run the below command to fix the permissions:

[email protected]:~#chmod +x ./configure –enable-optimizations

This shall perform many checks to make sure that all the dependencies are installed on the system. The -enable-optimization is used here to optimize the Python binary by executing many different tests. This sets various variables according to best practices identified by the Python community over the years.

Step 4: Finally, now install Python on Kali Linux

At this point you need to start with the build process by running the command mentioned below:

[email protected]:~#make –j4

You shall modify –j in accordance with the cores of the processor. My own laptop has a quad-core so it will be -j4 for me.

Install Python Binaries on Kali Linux

As the build process is completed, you need to run altinstall in order to Install python binaries on Kali Linux:

[email protected]:~#make altinstall

Keep in mind to never use “make install” to install binaries as it will automatically overwrite the binary files.

Finished! Python has now been installed on Kali Linux. You can now check the version by running the command below, if you want to verify it:

[email protected]:~#python –-version
