1.Dunder Methods: Modify the DunderObj class to make len(obj) return the product of two constructor parameters a and b, where obj is an instance of DunderObj and a and b are ints.

2.Dunder Methods: Modify the DunderObj class to make str(obj) return "a is larger than b", "b is larger than a", or "a and b are equal", depending on the values of two constructor parameters a and b.

3.Dunder Methods: Add a constructor to the PersonObj class to make str(obj) return if a person will be able to afford their rent.
