How to use Trinket:

On the left is your text editor section. You can edit and make changes to your code here. Notice how you're currently editing the main.py file.

On the right is the result and instructions tab. The result section is where your outputs will appear.

Run your code by clicking the little triangle on top. This will basically do python main.py.

You can switch to interactive mode with the dropdown arrow next to the Run button.
