F-Strings.

Fourth class. You often want to mix text and values in one message.

An f-string starts with f before the quotes. Inside {} you put an expression: f"{name} scored {score}". The expression is evaluated and inserted as text.

You can compute inside: f"next: {score + 1}". That is clearer than concatenating with + and str().

Mini example:

name = "Ada"
n = 10
print(f"{name} has {n}")
print(f"next {n + 1}")

Common mistake: forgetting the f before the quotes — then {name} prints literally; or adding unnecessary quotes inside {}.
