What are the differences between f-strings and format in Python 3.10?

What are the differences between f-strings and the format method in Python 3.10?

F-strings are a more concise and readable way to format strings in Python 3.10 compared to the format method. They allow you to embed expressions inside string literals using curly braces.

Can you give me an example of both methods?

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

Are there any performance differences between the two?

Yes, f-strings are generally faster than the format method because they are evaluated at runtime and do not require additional function calls.

Which one should I use in my projects?

If you're using Python 3.6 or later, f-strings are recommended for their simplicity and performance. However, use format if you need compatibility with older versions.
