F-strings use a prefix f and curly braces {} to denote where the variable should be inserted. For example:
name = "John"
f"Hello {name}" // Outputs "Hello John"
F-strings were introduced in Python 3.6 and provide a simpler way of formatting strings than using the str.format() method.
A use case for f-strings is formatting strings with variables.
For example, you can use f-strings to create a personalized email or message that contains the user's name or other information:
name = "John"
message = f"Hello {name}, thank you for signing up!" // Outputs "Hello John, thank you for signing up!"`
F-strings are a powerful and convenient way to format strings in Python.
They allow you to quickly and easily embed variables into your strings, making it easy to create personalized messages or outputs.
The syntax is simple and intuitive, which makes it a useful Python component for developers of all skill levels.
