Create a flexible decorator for validating data types:

  1. Define the validate decorator, which should take data types (str, int, bool, etc.) as arguments and annotate them using the type keyword.

  2. Define the inner function that takes a function (func) as an argument.

  3. Define the wrapper function that takes *args.

  4. Check if each argument is an instance of one of the specified types.

  5. Functions should return:

  • The wrapper() should return the result of func() with the provided arguments.
  • The inner() should return wrapper without calling it.
  • The validate() should return inner() without calling it.
  1. Validate the snake_string() function for the str data type using the @validate decorator.

  2. Validate the multiply() function for the int or float data types using the @validate decorator.
