What are the differences between f-strings and format in Python 3.12?

Can you explain the differences between f-strings and the format method in Python 3.12?

Sure! F-strings are a more concise and readable way to format strings, introduced in Python 3.6. They allow you to embed expressions inside string literals using curly braces. The format method, on the other hand, is older and uses placeholders in the string.

What are the advantages of using f-strings over the format method?

F-strings are generally faster and more readable. They allow for inline expressions, which can make the code cleaner. Additionally, they don't require you to specify the order of arguments, as you can directly reference variables.

Are there any limitations to using f-strings?

Yes, f-strings can only be used in Python 3.6 and later. They also require that the expressions inside the curly braces be valid Python expressions.

Can you give me an example of both methods?

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