What are advanced f-strings in Python 3?

Advanced f-strings in Python 3 allow for more complex expressions and formatting within string literals. They enable you to embed expressions directly inside string literals, using curly braces.

Can you give me an example of using f-strings with expressions?

Sure! For example, you can do something like this: name = 'Alice'; age = 30; print(f'{name} is {age} years old.').

How can I format numbers using f-strings?

You can format numbers by specifying the format within the curly braces. For instance, value = 123.456; print(f'The value is {value:.2f}') will output 'The value is 123.46'.

Are there any limitations to using f-strings?

Yes, f-strings can only be used in Python 3.6 and later, and they cannot be used in situations where the string is not a literal.
