What does the @ symbol inside the brackets represent in the given code?

The @ symbol inside brackets typically represents a decorator in Python. Decorators are a way to modify or enhance functions or methods without changing their actual code. They are often used for logging, access control, memoization, and more.

For example:

@decorator_function
def my_function():
    pass

In this case, decorator_function is applied to my_function, modifying its behavior when it is called. If you have a specific code snippet in mind, please share it for a more detailed explanation.
