How can I use newline "\n" in an f-string to format output?

📝🤔 How can I use newline '\n' in an f-string to format output? 🤔📝

Are you stuck trying to use the newline character '\n' inside an f-string to format your output? Don't worry, you're not alone! Many Python developers have faced this issue and struggled to find a solution. But fear not, because in this blog post, I'll show you an easy workaround that will have your code printing newlines in no time! 💪

Let's start by taking a look at the code example you provided:

names = ['Adam', 'Bob', 'Cyril']
text = f"Winners are:\n{'\n'.join(names)}"
print(text)

Seems like a straightforward approach, right? Unfortunately, Python doesn't allow the use of backslashes '\n' inside the curly braces of an f-string. This limitation is because backslashes are used to escape characters within the string itself, not within the expression portion of the f-string. 😩

But fret not, my fellow developer! There's a simple workaround to achieve the desired output. Instead of using the '\n' character directly in the f-string, we can use the newline character's ASCII representation: '\x0a'. Let me show you how to modify the code:

names = ['Adam', 'Bob', 'Cyril']
text = f"Winners are:\n{'\x0a'.join(names)}"
print(text)

By using the ASCII representation '\x0a' instead of '\n', we trick the f-string into interpreting it as a newline character. When we run the modified code, we get the desired output:

Winners are:
Adam
Bob
Cyril

Voila! 🎉

Now that you know how to use newline characters in an f-string, don't let this limitation hold you back. Get creative with your formatting and make your output shine! 🌟

But remember, with great power comes great responsibility! Be careful not to misuse this workaround and confuse future developers who might come across your code. Use it wisely and sparingly. 😉
