[Python] Python invalid syntax for print("Hello, world!")

I don't understand why I get the error for invalid syntax for my simple code print("Hello, world!")

I've installed Python in my pc. I'm running it on the cmd, changed my directory to the one where my file is at, but I still get an error.

Here is what my cmd says when I get the error:
