Challenge: Type Validation Decorator

Opgave

Swipe to start coding

Create a decorator that validates the input data for a function, and ensure that it is flexible enough to handle functions that take a varying number of arguments.

Define the int_validate decorator that takes a func (function) as an argument.
Inside int_validate(), define a wrapper function that takes a varying number of arguments.
For each argument, check if its type is int. If the type is not int, raise a TypeError with the message "The function expects the integer type".
Call the func() with the arguments taken by wrapper(), and return its result (don't forget to unpack the arguments).
The int_validate() decorator should return the wrapper function without calling it.
Decorate the int_sum() function using the int_validate decorator.
