Choose a first coding exercise
Three videos for your first day of coding
Create a file with OpenTutorials, sample Lefty Kim’s Python teaching style, or compare code and output with Dongbin Na. Start with the task you want to try.
To make your first file and see it work, start with OpenTutorials. If Python feels intimidating, try Lefty Kim’s course introduction. To compare code with its output, jump to Dongbin Na’s string-printing example.

OpenTutorials — make your first file
If you would rather see a small result than spend another hour choosing a course, watch this roughly five-minute HTML setup lesson. In an editor, the instructor creates 1.html, types Hello world, saves the file and opens it in a browser. The same sentence appears on the page.
Start at the beginning if you need the browser and VS Code setup. If those are ready, begin making the file at 02:54. The goal is to open one file on your own computer. Publishing a website online and learning HTML tags come later. This is the 2023 revised lesson, so today’s installation screens may differ.

If you have wondered why Python feels hard when everyone calls it easy, listen to this 1-minute-27-second introduction. Lefty Kim begins by acknowledging that a language can be relatively easy and still be difficult for a first-time learner. At 00:25–00:58, he describes a course for complete beginners and people who have given up several times.
Published in 2018, this is a course introduction, with no installation or coding exercise. Use it to hear the instructor’s style and decide whether to continue. Later, he explains that the course uses a book and that some projects and exercises are in it. If you want to type code immediately, the next example is a closer match.

Once you have decided to try Python, watch 16:32–17:25. Dongbin Na writes strings in quotation marks and displays them with print. Compare the sentence in the code with the sentence in the output panel. The full lesson is about 90 minutes; you do not need to finish it on day one.
To follow along, you need a Python environment on a computer. If that is not ready, return to the installation explanation at 09:12. The video shows a 2024 PyCharm and Python setup, which may differ from the current installer. A useful first task is simply to replace an example sentence with your own and print it.
