Is immutable and hashable. That means it can be used as a key in a dictionary or as an element in a set. <frozenset> = frozenset(<collection>) Tuple Tuple is an immutable and hashable list. <tuple> = () <tuple> = (<el>, ) <tuple> = (<el_1>, <el_2>, ...) Named Tupl...
One of the core design aspects of Postgres is immutable row data. These immutable rows are called “tuples” in Postgres parlance. These tuples are uniquely identified by what Postgres calls a ctid. A ctid conceptually represents the on-disk location (i.e., physical disk offset) for a tupl...
This is going to be a very short section. In Haskell all data is immutable. Period.Let's look at some interactions with the Haskell GHCi REPL (whenever you see the λ> prompt in this article it is from a GHCi session):λ> a = [1,2,3]λ> a [1,2,3]λ> reverse a [3,2,1...
