#yes it's possible using frozen set
#frozenset() is an inbuilt function is Python 
#which takes an iterable object as input and makes them immutable
#Syntax : frozenset(iterable_object_name)
#Parameter : This function accepts iterable object as input parameter.
#Return Type: This function return an equivalent frozenset object.
# making it frozenset type 
f_num=frozenset(myfavnumbers)  
# below line will generate error
