Python Language Immutable datatypes(int, float, str, tuple and frozensets) Frozenset's are immutable and not assignable


foo = frozenset(["bar", 1, "Hello!"])
foo[2] = 7 # ERROR
foo.add(3) # ERROR

Second line would return an error since frozenset members once created aren't assignable. Third line would return error as frozensets do not support functions that can manipulate members.
