How to run Python Programs on Raspberry Pi? Beginner Tutorial

Own a Raspberry Pi and need a simple tutorial on how you can start create and run your own programs on Python? You’re in the right place today! In today’s post, I’ll introduce Python, why it is commonly used, and most importantly how you can get started with projects alongside it!

Before we get started…

Introduction to Python

What is Python and Why is it used in Raspberry Pi?

Python Org

Python is a widely-used programming language with an easy, beginner-friendly syntax (arrangement of words, phrases, in sentences). Due to its wide adoption, it has a huge community, giving access to libraries, frameworks, and tools to help users get started!

For Python to run any platform, it requires a Python Interpreter, and since Linux, an OS for the Raspberry Pi has been written for it, running of Python Interpreter has no issues.

  • Hence, it is used for the Raspberry Pi, starting off as a scripting language to a full-fledged programming language option for software configurations!

What is python used for

Since Python is a multi-purpose programming language, it can be used for many useful applications in different industries as such:

  • Web development and applications
  • Creating GUI applications
  • Game development, programming, and computing
  • Automation
  • Machine learning and Artificial Intelligence
  • Raspberry Pi projects such as turning LED on and off, etc.

Some of the applications sound complex? But with Python, you can simply solve complex problems or applications with fewer lines of code, saving both time and effort!

Python vs C# and JavaScript

Lastly, before we begin our tutorial, let us have a quick comparison between Python and other programming languages; C# and JavaScript. To not dwell further, we’ll just take a look at the main differences:

Language complexity and Ease of Usage:

We’ve now established earlier that Python uses a much simpler language, but what about C# and Java? C# is much complex as you need to know more language constructions, while Java being a full-formed web programming is a lot to learn. A simple example is the below codes when extracting the first three letters of “Hello World”:

  • Python:
  • C#
str.Substring(0, 3)
  • JavaScript:
str.substr(0, 3)

Simpler, Shorter, Easier with Python!

Cost of Development Time and Performance

C# and Java are compiled languages, allowing for faster performance. However, when changes are made, there’s high development time as you’ll have to wait for the program to compile.

However, with Python, you can just restart your application and continue on!

Community Support

Both Python and Java have been open-source languages for a long time, whereas C# has just recently become that. Hence, community support for Python and Java will be bigger.

This means, if you stumble across any problems, the likelihood of finding solutions to those two languages is higher!

All in all, very much everything you do on Python can be done with other programming languages such as C# and Java. With its simpler usage, it makes a better option for beginners to get started.

How to Download and Run Python 3

Of course, to first get started you’ll need to install Python. Good news if you’re using Raspbian, the default OS for Raspberry Pi as it should contain both Python 2 and 3 IDE!

So go ahead and load it up by clicking on the Top left Pi icon -> Programming -> Python 3 (IDLE)

However, if for some reason you do not have python in your system, simply launch the terminal window (4th icon from the left) and run this command at the command prompt:

sudo apt-get install python3

If you’re running on other OS such as Ubuntu, Debian, and LinuxMint, here’s how you can install Python 3.7:

  • Step 1: Install Prerequisites
sudo apt-get install build-essential checkinstall
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev \
    libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev zlib1g-dev
  • Step 2: Download Python 3.7
cd /usr/src
sudo wget

Extract the download package with this:

sudo tar xzf Python-3.7.4.tgz
  • Step 3: Compile Python Source Code using Altinstall
cd Python-3.7.4
sudo ./configure --enable-optimizations
sudo make altinstall
  • Step 4: Check the Python version installed
python3.7 -V


Writing your first Python Program with Hello World!

Hello, World? It’s a program aimed to help beginners get started in writing your first Python Program in the interpreter. It allows you to test out commands one line at a time!

  • Step 1: Launch the Python Interpreter and enter the following command:
  • Step 2: You should see “>>>” sign, where you’ll have to type the following command in and press enter:
print("Hello, World!")
  • You should then see the phrase Hello, World! replied back to you

That’s all it took for you to run your first Python program! Simple right?

  • You can now exit the interpreter by entering the following command:

Learn Python through Mathematical Expressions

Apart from “Hello, World”, you can learn python with Raspberry Pi through programming the interpreter to perform mathematical calculations with operator signs:

Operation Symbol Example
Power (exponentiation) ** 5 ** 2 == 25
Multiply * 2 * 4 == 8
Divide / 15 / 3 == 5
Integer Division // 14 // 3 == 4
Remainder (modulo) % 14 % 3 == 2
Add + 2 + 2 == 4
Subtract 4 – 3 == 1

Want to get started? You can test it out by running the commands below:

print("3 + 3 is", 3 + 3)
print("3 * 4 is", 3 * 4)
print("100 - 1 is", 100 - 1)
print("(33 + 2) / 5 + 11.5 is", (33 + 2) / 5 + 11.5)

When the above command is run, you’ll see the following output:

3 + 3 is 6
3 * 4 is 12
100 - 1 is 99
(33 + 2) / 5 + 11.5 is 18.5

For more complex mathematical functions, you can visit the relevant python libraries!

Running Program via Thonny

Another way you can run a python program is through Thonny. Thonny is a Python Editor ith a beginner-friendly environment with features suitable for writing codes and running programs!

If you’re running on Raspbian, simply head to the Pi icon -> Programming -> Thonny Python IDE as follows:


Once Thonny is launched, click File > Open, and then navigate to your Python program. Once program is loaded, click Run > Run the current script

Using other Linux OS? You can visit the Thonny Website to download Thonny for Linux OS here!

How to run Python through Raspberry Pi GPIO pins

What’s unique of running python on Raspberry Pi instead of the typical PC is that you can run codes specifically to control hardware components through its GPIO pins! In today’s tutorial, I’ll start by teaching you how you can code an LED to turn it on and off!

You’ll need the following hardware components:

Hardware Assembly and Configurations:

  • Step 1: Plug the Grove Base Hat into Raspberry
  • Step 2: Select any GPIO port on the Base Hat and connect the Purple LED to it
  • Step 3: Connect the Raspberry Pi to PC through USB cable

For step 2, you can connect it to the Grove Port as well, which would result in the pairing to look like this:

Software Configurations with Python

  • Step 1: Follow Setting Software to configure the development environment
  • Step 2: Download the source file by cloning the library
cd ~
git clone
  • Step 3: Execute the following command. Take note of the GPIO port you’ve connected the Grove – Purple LED to and enter it under port number.
cd yourpath/
python portnumber

If your port number is 12, your command should look like this:

cd yourpath/
python 12

You should now be able to see the LED on and Off!
