some objects outputs values in a different order they are added to the object (e.g. set class). more important in this case is to observe that any object becomes iterable in a statement 'for ... in' if it's defined to it (i.e., a class definition) to dunder __iter__. In ...

In software testing, there is an approach known as property-based testing that leverages the concept of formal specification of code behavior and focuses on asserting properties that hold true for a wide range of inputs rather than individual test cases. Python is an open-source programming langua...
