When it comes to coding, there are three programming languages you can learn when using Raspberry Pi; Python, Java and JavaScript.

Python is considered the most popular programming language across the globe. Furthermore, its interpreter has been made available in all popular Linux distributions. 

Once you install Raspbian Operating System in a Raspberry Pi, you will come across an app known as Thonny; this is a Python IDE (integrated development environment) ideal for beginners.

Furthermore, working with Python programming language is relatively easy compared to other programming languages available in today’s market. As a result, in this article, we shall be discussing how to load code into Raspberry Pi using Python programming language as an example.

Before jumping into the process of loading code into Raspberry Pi using Python programming language, it is best you understand more about this programming language. Well, as a newbie, the first thing you need to understand is that Python programming language is capable of automating tasks such as moving large files as well as renaming batches.

It might as well be used as a command-line using IDLE, Python’s read, eval, print, loop (IDLE) function. In addition to that, Python can be used in performing several essential tasks such as:

  • 2D games
  • Desktop apps as well as utilities
  • Small databases
  • Web applications
  • Special GUIs

Additionally, Python programming language features incredibly extensive collections of libraries that aids in speeding up the process of development. The program is equipped with libraries for almost everything that you can think of including gaming programs, GUI interfaces, rendering graphics, scientific computing and web frameworks.

Several but not all things that can be performed in C can as well be done in Python. You should note that the Python Programing language is relatively slower when it comes to computations compared to C. 

However, it is relatively easy to make Python as an ideal language for designing applications as well as prototyping which are not computationally intensive.

Loading code into Raspberry Pi

When it comes to loading codes into a Raspberry Pi using Python programming language is relatively easy and does not require any advanced skills. First of all, you will have to install the Python programming language in your Raspberry Pi before you commence on the coding process. 

Fortunately, Python 2, as well as Python 3, comes pre-installed on the Raspbian OS; however, when it comes to Linux OS, you will have to install it. In case, you would like to install or update Python programing language when using Linux OS; you will have to key in the following commands:

sudoapt-getinstallpython3; this command is for installing or updating Python programming language 3.

sudoapt-getinstallpython; this command is for installing or updating Python programing language 2.

Once you have your Python programming language installed and running, you will proceed to write code. To do this, we shall demonstrate by creating and executing the Python programing language; we shall create a “hello world”. To do this, you will begin by first opening a Nano text editor and then create a file which you will name it; you should enter this command in order for you to achieve it. 

Ensure that the command is entered into Nano; to exit and save your file, you will have to click Ctrl-X and Y.

You should note that all Python files have to be named and saved using the “.py” extension. Furthermore, you might as well consider writing your program in any text editor that you find the best such as Notepad++ or Notepad; however, ensure that your file is saved using the “.py” extension.

Running Python programing language

In order for you to run Python programming language on your Raspberry Pi, you will have to make it executable. To do this, you will have to go to the location where your file is saved and then key in this command

Once you have that done, you will go ahead and make your Python programming language executable. By making your Python file executable, you will be able to run it without having to key in Python prior to your file name. Enter this command to help in making your file executable: chmod+x Without done you will only now be required to enter ./ in order for you to run your program.

Some essential resources that will assist you in making most uses of a Python programing language include:

  • Completing the list of your Python library
  • Completing the list of the Python syntax
  • PyPI (Python Package Index)
  • Install Python packages on your Raspberry Pi

Why loading code into Raspberry Pi is vital

Without the use of codes, your Raspberry Pi will become useless since they will not be able to do any vital task. This is because source code is a set of instructions which helps in instructing the computer on what to do. This is vital since computers don’t have any free will; as a result, without any explicit instruction, computers become sophisticated metal hunks. 

Every application and software are designed using complex codes which helps in guiding a computer on what to do. Therefore, mastering how to load code into your Raspberry Pi becomes a vital task for all DIY enthusiasts out there.

Final word

Understanding how to load code into Raspberry Pi is highly essential. When it comes to coding, there are various programming languages that you might consider using; however, as a newbie, Python programing language is regarded as the best since it is relatively easy to use and understand compared to other programming languages available in today’s market. 

In addition to that, Raspbian Operating System comes equipped with a pre-installed Python programming language; this makes the whole process relatively easy since you will not have to install it afresh in your Raspberry Pi. 

Python programming language is less sophisticated, which makes it the best programming language for novices to learn coding with the utmost ease. As we come into conclusion, we hope that you find this article beneficial as you learn how to load code into Raspberry Pi.
