Format Currency (Solution)

00:00 In the previous exercise, you practiced formatting a floating-point value requesting a specific number of digits after the decimal point. Here, even though we are dealing with an integer, we can actually use the same syntax as before.

00:14 So we’ll start solving this exercise from the end. Let’s first format the given integer literal as a floating-point value with two decimal places. This automatically adds the two zeros after the decimal point, even when the number has no fractional part to begin with.

00:33 Now, to group the thousands, you can include a comma in the formatting string like so.

00:39 The comma has to come before the .2f. If the amount gets bigger by any chance, then Python will add the subsequent commas as necessary.

00:50 We’re almost there. The last point, which isn’t explicitly listed in the exercise instructions, is about adding the currency symbol. We’re working with a currency, after all.

01:01 You can combine the format() function with an f-string literal to add that symbol. However, since we’re already using an f-string, we can just go ahead and do this all within the f-string literal.

01:20 Okay, that looks like a beautifully formatted currency to me. I’m actually quite happy with it. So let’s move on.
