Executing Python scripts using the Linux Terminal

It is possible to execute code written using any text editor via the Linux Terminal. For example, Let's say the file helloworld.py is saved in a folder named code_samples on the Raspberry Pi's desktop. This file may be executed as follows from the Linux Terminal:

If you are not familiar with the Linux command-line terminal, we have written up some tutorials to familiarize yourself with the command-line terminal on this book's website.

1. On the Linux Terminal, switch to the directory where the Python script is located:

       cd /home/pi/Desktop/code_samples

1. Execute the Python script as follows:

       python3 helloworld.py

1. Alternatively, the Python script could be executed using its absolute location path:

       python3 /home/pi/Desktop/code_samples/hello_world.py

We did it! We just wrote our first piece of code and discussed different ways to execute the code.
