what does the @ in python do

Great question ! The `@ ` symbol in Python is used in several ways , but I ' ll focus on its most common usage : \n 1 . Ass ign ing a value to a variable : You can use the `@ ` symbol to assign a value to a variable . For example : \n ``` \n x = 5 @ y = 1 0 \n ``` \n In this code , ` x ` is assigned the value ` 5 `, and ` y ` is assigned the value ` 1 0 `. \n 2 . An not ating a function or class : You can use the `@ ` symbol to annot ate a function or class with metadata . For example : \n ``` \n def gre et ( name : str ) -> None : \n print ( f " Hello , { name } ! ") \n ``` \n In this code , the ` g reet ` function is annot ated with the ` str ` type for its ` name ` parameter , indicating that it expects a string value . \n 3 . Dec or ating a function or class : You can use the `@ ` symbol to decor ate a function or class with additional functionality . For example : \n ``` \n def log _ function ( func ): \n def wrapper (* args , ** kwargs ): \n print ( f " Call ing { func .__ name __ }") \n return func (* args , ** kwargs ) \n \n @ log _ function \n def gre et ( name ): \n \n print ( f " Hello , { name } ! ") \n \n ``` \n In this code , the ` log _ function ` decor ator logs a message whenever the ` g reet ` function is called . \n Th ese are just a few examples of the many ways the `@ ` symbol is used in Python . If you have any specific questions about these or other uses of the `@ ` symbol , feel free to ask ! </s>
