It does not create a new type hence does not increase type safety. It can be used to shorten a long name. It can be used to shorten a long name. Languages allowing type aliasing include: C++ , C# Crystal , D , Dart , Elixir , Elm , F# , Go , Hack , Haskell , Julia , Kotlin , Nim , OCaml , Python , Rust , Scala , Swift and TypeScript .
Structural typing is a static typing system that determines type compatibility and equivalence by a type's structure, whereas duck typing is dynamic and determines type compatibility by only that part of a type's structure that is accessed during runtime. The TypeScript, [6] Elm [7] and Python [8] languages support structural typing to varying ...
Cython provides optional manual memory management by letting the user import malloc, realloc, and free from C, which they can then use in Python code. [18] D provides programmers with full control over its own garbage collector, including the ability to disable it outright. [19]
Python's is operator may be used to compare object identities (comparison by reference), and comparisons may be chained—for example, a <= b <= c. Python uses and, or, and not as Boolean operators. Python has a type of expression named a list comprehension, and a more general expression named a generator expression. [78]
Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})

This is a comparison of the features of the type systems and type checking of multiple programming languages.. Brief definitions A nominal type system means that the language decides whether types are compatible and/or equivalent based on explicit declarations and names.
