How do Python f-strings compare in performance to other string formatting methods?

How do Python f-strings compare in performance to other string formatting methods?

Python f-strings are generally faster than the older methods like '%' formatting and 'str.format()' due to their direct evaluation.

Can you provide some benchmarks or examples to illustrate the performance differences?

Sure! In many benchmarks, f-strings can be up to 20% faster than 'str.format()' and significantly faster than '%' formatting.

Are there any scenarios where using f-strings might not be the best choice?

Yes, if you're working with very complex expressions or need to support Python versions earlier than 3.6, f-strings won't be suitable.

What about readability? Do f-strings affect the readability of the code?

F-strings are often considered more readable because they allow for inline expressions, making the code cleaner and easier to understand.
