First Words

Every Monday morning, you open a spreadsheet with 200 rows of sales data. Customer names in column A, amounts in column B, regions scattered across column D. You scroll to the bottom, type a SUM formula, copy it across three cells, fix the one that broke, format the dollar signs, email it to your manager, and close the laptop feeling like you just did the same thing you did last Monday. And the Monday before that. This week, you learn to speak Python. Not fluently -- not yet -- but enough to say what you mean. You will write your first function: a small, reusable block of code that takes a customer name and a sale amount and formats them exactly the way your manager wants. Then you will teach that function to make decisions -- flag the big sales, skip the empty rows, handle the edge cases that always trip you up in Excel. By Friday, you will feed it five sales records in a loop and watch it process all of them in under a second. The surprising part is not that Python can do this. It is how little code it takes. The function you build on Day 3 is four lines long. By Day 7, the entire program that processes your sales list fits on a single screen. No scrolling. No broken cell references. No copy-paste errors. Your first word in any language feels strange in your mouth. Let's get that over with.
