Using an IDE

I really suggest you to use a modern IDE for coding. For this example I'll use Visual Studio Code aka VSCode, but you can choose another one. Python website has a page to show you some recommended IDEs to use.

When VSCode is installed, you can click on Extensions icon and type Python on search bar. Then you can click install under Python extension developped by Microsoft.

Now you able to write your first code. For that you can create a new file called hello.py. Insert the a code inside this file.

print ('Hello world!')

and run it to see the result on the terminal.
