  • inject or modify code in functions or classes
  • applied to a function definition
  • 8 more annotations...
  • • the resulting function object is passed to the myDecorator code
    • produce a function-like object
    • creation of f() is complete before the decorator is called
    • constructor for myDecorator is executed at the point of decoration of the function
    • capture the function object in the constructor and later use it in the __call__() method
    • pass a function object through another function and assign the result to the original function.
    • The only constraint on the result of a decorator is that it be callable
    • return new_f
