What are f-strings in Python 3.10?

What are f-strings in Python 3.10?

F-strings, or formatted string literals, allow you to embed expressions inside string literals, using curly braces. They were introduced in Python 3.6 and are enhanced in Python 3.10.

Can you give me an example of how to use f-strings?

Sure! Here's a simple example: name = 'Alice'; age = 30; print(f'{name} is {age} years old.') This will output: 'Alice is 30 years old.'

What are the benefits of using f-strings over other formatting methods?

F-strings are more readable and concise compared to older methods like % formatting or str.format(). They also evaluate expressions at runtime, making them more powerful.

Are there any limitations to using f-strings?

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