An update coming to Google Docs will make code formatting easier on the app. It plans to add code blocks to its "smart canvas" system that will automatically add proper spacing and colour-coding for programming languages like Python, Javascript, and C. You needed add-ons before to make this possible. But now, it'll be much easier to display code properly for documentation. The feature is accessible through Insert > Building Blocks > Code Block and then selecting the relevant language. You can also type "@project assets" into your documents to pull up the menu.
It might take some time for the feature to roll out, though. Google says some users may not even have access to it by January 18, depending on their Workspace settings. This is also only available to specific subscription tiers. If you’re using a personal Google account, a legacy G Suite account, or various Essential and Starter Workspace tiers, you won’t have access to it.
