Hello World

Created by Julien Palard

Welcome on HackInScience!

This is a sample exercise just to familiarize with the system.

On the right, here, there's typically the exercise instructions, for example: "Write a single line of Python code to display Hello world!".

The code to solve the exercise is to be written in the black code editor, on the left of the page.

But as it's just an example, I already wrote the code for you ☺

Below the instructions you can see some buttons, the more important is the blue one, the Submit button used to send your answer to the correction bot. The bot will review and test your code, and will tell you if it's valid of if you have something to enhance.

Once your exercise approved by the correction bot, you'll be authorized to read shared answers (middle button under the instructions), and click on the button to continue to the next exercise.

What to do now

Start by reading the tutorial.

Play around with the code (modify the text, click Submit, drop a parenthesis, click Submit, add the parenthesis back, click Submit, ... as many times as needed to experiment with the syntax and possibilities.

But beware, the bot will still want you to print Hello world! to validate the exercise!

There's no corrections yet, hit the `Submit` button to send your code to the correction bot.

Keyboard shortcuts:

  • Ctrl-Enter: Send your code to the correction bot.
  • Escape: Get back to the instructions tab.
