As the Hacker Blogosphere is always on the move, the best Python IDE of the year 2016 is out, and here is an easy step-by-step guide to install and setup your brand new Python 3 environment on your Raspberry Pi 2 or Raspberry Pi 3 Model B+.
The Raspberry Pi is a mini-computer board designed to allow the tinker and experimenter to learn about the operation of computer systems. A complete guide to setting up the Raspberry Pi can be found on the Raspberry Pi website. In this guide, I describe how to use a script to update the Linux operating system so that you get the latest and greatest version of Python installed on the Raspberry Pi.
In this post, we will guide you to install Python 3.7.1 on Raspberry Pi. Read more about install python 3.6 raspberry pi and let us know what you think.Raspberry Pi and Python work well together, and Python is pre-installed on your Raspberry Pi operating system. But, as is often the case with computers and programming, things are not always that simple. In this article, I’ll explain and show you everything you need to know about the versions of Python on your Raspberry Pi. The only way to install the latest version of Python on the Raspberry Pi operating system is to download it from the official website and install it from source. The Raspberry Pi OS repositories are usually a few versions behind. As always, I do this on my Raspberry Pi, so you don’t have to deal with bugs and errors yourself. Follow my recommendations below and everything should work the first time!
To find out which version of Python is installed
Two versions of Python are pre-installed on the Raspberry Pi operating system: Python 2 and Python 3. To know the exact version number, use the command line python -version and python3 -version. alt= width=454 height=119 data-ez= data-ezsrc=http://server.digimetriq.com/wp-content/uploads/2021/06/How-To-Install-the-Latest-Python-Version-on-Raspberry-Pi.jpg /> It may be a bit confusing, but yes, you already have two versions installed on your Pi. If you use the python command to run a script, run it with Python 2. And the python3 command does the same thing with version 3. The exact version depends on the latest version available in the Raspberry Pi OS repository. In most Debian-based distributions, these versions are a bit outdated. At the time of writing, Python 3.7.3 is two years old and pre-installed on the Raspberry Pi operating system. If you wanted to know how to use Python 3 on your Raspberry Pi, you now have the answer: Use the python3 command instead of python. And if you want to install a newer version, read on to find out how.
Find the latest version of Python
The easiest way to find the latest version of Python is to visit the official Python website. The download page lists the latest versions with release date and maintenance status. alt= width=1024 height=294 data-ez= data-ezsrc=http://server.digimetriq.com/wp-content/uploads/2021/06/1622972140_140_How-To-Install-the-Latest-Python-Version-on-Raspberry-Pi.jpg /> This first table gives an overview of the latest versions of Python. As you can see from the download page, Python 3.7 was released in 2018. In the next section, you will learn how to update it on your Raspberry Pi.
Install the latest version of Python on your Raspberry Pi
Since the Raspberry Pi operating system is still a few versions behind Python, the only way to install the latest version of Python on your Raspberry Pi is to download the source code from the official website and install it manually.
Loading and unloading
- Go to the Python download page.
- Search the second table on this page Are you looking for a specific output? : alt= width=682 height=182 data-ez= data-ezsrc=http://server.digimetriq.com/wp-content/uploads/2021/06/1622972141_163_How-To-Install-the-Latest-Python-Version-on-Raspberry-Pi.jpg />
- Click on the download link corresponding to the version you wish to install. In my case, I will be installing Python 3.9.5.
- Scroll to the bottom of the page and find the list of download links: alt= width=533 height=200 data-ez= data-ezsrc=http://server.digimetriq.com/wp-content/uploads/2021/06/1622972142_715_How-To-Install-the-Latest-Python-Version-on-Raspberry-Pi.jpg />.
- Right-click on the compressed source archive and select Copy Link Address from your browser’s context menu.
To perform the following steps, you must open a terminal on the Raspberry Pi’s operating system or connect via SSH to enter certain commands. If you need help with the SSH part, you can read my guide here, which has all the information you need.
- Download the latest Python file with: wget https://www.python.org/ftp/python/3.9.5/Python-3.9.5.tgz Replace the URL with the link you pasted in the previous step.
- Extract the files with: tar -zxvf Python-3.9.5.tgz Change the version of Python if you downloaded a different version.

Configuring and installing the latest version of Python
We now need to compile the source code to install this version of Python on your Raspberry Pi:
- Navigate to the folder with the extracted files: cd Python-3.9.5
- Run the configuration command: ./configure –enable-optimizations Since Python is already installed on your Raspberry Pi, it should work immediately. However, if you get an error message, you probably need to install or upgrade the missing components.
- Then run this command to install: sudo make altinstall
This takes a few minutes, depending on the model and version of the Raspberry Pi (5 to 10 minutes for the Raspberry Pi 4).
Make Python 3 the default version on the Raspberry Pi operating system
Each version of Python installed on your system adds a new executable to /usr/local/bin that you can use to run the program. In my case, for example, I know what I have:
- python2.7 : The current default version of Python 2.
- python3.7 : The default version of Python 3 on the Raspberry Pi operating system at the time of writing.
- python3.9 : The one I installed from source.
But when I use python -version, I always use python 2.7. To select the version you want to run, you have two options:
- Always run a Python script with the exact version you want to use, for example. B: python3.9 myscript.py That’s probably the safest option if you change between versions regularly.
- Or you can replace the link in /usr/local/bin by pointing to the version you want to use by default.
This is what it looks like with a fresh install of the RPI operating system: alt= width=825 height=101 data-ez= data-ezsrc=http://server.digimetriq.com/wp-content/uploads/2021/06/1622972142_625_How-To-Install-the-Latest-Python-Version-on-Raspberry-Pi.jpg /> How to change this link :
- Change to /usr/bin: cd /usr/bin
- Remove the current shortcut: sudo rm python
- Put the link to the version you want to use: sudo ln -s /usr/local/bin/python3.9 python
- Check that everything is correct: python –version It should detect the version you just installed (3.9.5 for me).
alt= width=831 height=169 data-ez= data-ezsrc=http://server.digimetriq.com/wp-content/uploads/2021/06/1622972143_524_How-To-Install-the-Latest-Python-Version-on-Raspberry-Pi.jpg />Note: When you use Thonny to write Python code, the default is /usr/bin/python3, which refers to the latest version installed by the Raspberry Pi operating system (3.7.3 in my case). If you want to use the latest version of Python with Thonny, you should also update this link.
Updating Python on the Raspberry Pi
We’ve already seen how to install a specific version of Python on the Raspberry Pi operating system, but how do you update it from there? To update Python on your Raspberry Pi, first make sure your whole system is up to date : sudo apt update sudo apt upgrade Although the Raspberry Pi operating system is still a few versions behind the latest available version of Python, you can get updates with apt, just like for any other software on your device. Then check the current installed version with: python –version python3 –version If the required version is not there, follow these instructions from the beginning. Downloading the source code and compiling it to the correct version is the only solution for every update, there is no magic command to do this automatically.
Final thoughts
I hope this article has clarified for you how the versions of Python work on the Raspberry Pi. You now know that there are at least two versions installed and that you can easily switch from one to the other by changing the command used. Also check that you have installed the modules that belong to the version of Python you are using (python-gpiozero and python3-gpiozero are two different packages). There are also two versions of PIP (pip and pip3). This can be misleading for beginners, but it is very useful once you get used to it.
