Fixed digits after decimal with f-strings

Fixed digits after decimal with f-strings: The Easy and Cool Way! 🚀

Hello fellow Pythonistas! Let's dive into the wonderful world of f-strings and learn how to fix the number of digits after the decimal point with ease! 💃💻

The Problem 🤔

So, you're working on a Python project and you find yourself in a situation where you need to display a specific number of digits after the decimal point using f-strings. You may have tried various approaches but couldn't find an easy way. 🙄

The Solution 💡

Fear not, my friends! 👏 Python's f-strings are here to rescue you with a simple and elegant solution. 😎

To illustrate, let's take the example presented in the question where we have a variable a = 10.1234. If we want to display 2 digits after the decimal place, here's what you need to do:

a = 10.1234
result = f"{a:.2f}"

And boom! 💥 Using the :.2f syntax within the f-string, we have effortlessly fixed the number of digits after the decimal point to 2. How cool is that? 😍

You can replace 2 with any number of digits you desire! Imagine the possibilities! 🌈

Let's Break It Down ✂️

To understand how this works, let's deconstruct the format specifier :.2f:

• :: This character precedes the format specifier and is used to indicate the beginning of the format specification.

• .2: This represents the precision specifier and tells Python that we want to display 2 digits after the decimal point.

• f: This represents the type specifier and signifies that we are working with a float.

By combining these components, :.2f ensures that our number is displayed with the desired precision.

But Wait, There's More! 🎉

Now that we've mastered the art of fixing digits after the decimal point, let's explore some additional formatting options to level up your f-string game! 🚀

• Leading Zeros: If you want to display leading zeros before the decimal point, you can use the 0 character followed by the desired width. For example, result = f"{a:07.2f}" will display 010.12 for our original value.

• Thousand Separators: To make your numbers more readable, you can use the comma , character to add thousand separators. For instance, result = f"{a:,.2f}" will display 10.12 with the thousand separator.

Feel free to experiment and combine these formatting options to achieve your desired output! 🧪
