All language subtitles for 009 Running Python Scripts using the Command Line_en

Hi, and welcome back.

In this video, I'd like to show you another way to execute Python scripts, and that's using the terminal

or the command line.

This is especially useful when you connect to a remote machine or server using, for example, SSH and

run the python script on that machine.

You don't have access to a graphical environment to open python idle or pitch time to execute the script.

In fact, in this case, this is the only way to execute the script.

Let's create a Python script using any editor like Notepad or even Pixar.

You can use any other editor you like.

I'll write some Python instructions inside the script and the save it on the desktop.

Name equals.

Entry in a single coax and print.

Hello.

My name.

I'm saving the script on my desktop is my script to that PI.

This is the script.

Now I'll open cmd dot xy or a command prompt.

Go to desktop.

Check the content of the current directory by running the command.

In the run Python.

And the name of the script.

And you see how the script has been executed.

If you use Linux or Mac, open the Linux or the Mac terminal instead of CMD, ATX C and run Python three

instead of Python.

If you are not in the same directory as the Python script, you must use a valid, absolute or a relative

path.

Otherwise you'll get an error.

For example, I'm moving to the parent directory.

If I try to execute the script by running the same command.

So Python and the name of the script, I'll get an error.

That's not a valid path to the Python script.

No such file or directory.

Now I'm running the script using the correct path.

So Python, they stop with a capital D.

Slash or backslash.

You can use either of them.

And the name of the script.

My script to that pi.

Index.

Okay.

The script was run successfully.

Great.

In this lecture you've learnt how to run Python scripts directly in the terminal.

This is useful when you want to run a Python script on a machine without a graphical environment such

as a server or on a computer without PI charm or other ID installed.

Of course python should be installed on that machine.

With this video we have completed the first section of the course on set up the programming environment.

So next we are going to have a quick quiz just to make sure that you've deeply understood how to run

your Python scripts.

Good luck with the quiz and I'll see you in the next section where we'll talk about Python basics,

such as variables, comics built in data types, operators and many more.
