Frozen sets in python are immutable objects that only support methods and operators that produce a result without affecting the frozen set or sets to which they are applied. Matlab and python may help you in this realm of study. For example, if you want to find intersection of two sets, you can use intersection method. Also, the page includes builtin functions that can take set as a parameter and perform some task. Python has quite a few methods that set objects can all to perform frequency occurring task related to set. If no parameters are passed, it returns an empty frozenset.
