What are the differences between Python f-strings and the format method?

Python f-strings, introduced in version 3.6, allow for inline expressions and are generally more concise. The format method, available since Python 2.7, uses placeholders and is more verbose.

Can you give me an example of both?

Sure! For f-strings: name = 'Alice'; greeting = f'Hello, {name}!'. For the format method: greeting = 'Hello, {}'.format(name).

Which one is more efficient?

F-strings are generally faster and more efficient because they are evaluated at runtime and do not require additional method calls.

Are there any limitations to using f-strings?

Yes, f-strings can only be used in Python 3.6 and later, and they cannot contain single quotes or double quotes that conflict with the string delimiters.
