F-strings are lines in a string that contain interpolated expressions. They look like this: "Python f-string".
The expression that is interpolated will be evaluated within the context of the string and the results will be assigned to the variable that is specified as the value for the f variable.
There are a few important things to keep in mind when working with F-strings in Python:
They can be used anywhere that strings can be used. This includes withinitute strings, function arguments, and even comments.
They support most of the standard string operations, including concatenation, substitution, and iteration.
They have their own special evaluation context which means they can access values stored in variables that are defined inside of them.
