Can someone explain what is usage of f-string . I mean print(f" ghh {} ") . What can be in brackets?

Question

Python

Answer 1

Also called “formatted string literals,” f-strings are string literals that have an f at the beginning and curly braces containing expressions that will be replaced with their values. The expressions are evaluated at runtime and then formatted using the __format__ protocol.

Eg:
x = 7
print (f"T he value of x is {x}")
