Constants prevent silent bugs, make regulatory thresholds explicit, and transform magic numbers into readable code. Learn how to use them properly in finance calculations.
Print is your window into what your code is actually doing. In finance work, where a single error cascades through reports, print is not optional—it's your primary tool for validating logic before it goes live.
Good comments signal assumptions and protect your code from breaking when someone else reads it. Learn when to comment, what to say, and how to build the habit so your code is safe to hand over and clear enough to audit.
