How can I use f-strings for complex expressions in Python 3.12?

In Python 3.12, f-strings allow you to embed expressions inside string literals. You can use them for complex calculations directly within the string.

Can you give me an example of using f-strings with a list comprehension?

Sure! Here's an example: numbers = [1, 2, 3]; result = f'The squares are: {[n**2 for n in numbers]}'.

What about using f-strings with functions?

You can do that too! For instance: def square(x): return x**2; print(f'The square of 4 is {square(4)}').

Are there any limitations to using f-strings?

Yes, f-strings cannot contain single quotes or double quotes that conflict with the string delimiters, and they can't be used in certain contexts like function annotations.
