Dynamically typed languages (where type checking happens at run time) can also be strongly typed. In dynamically typed languages, values, rather than variables, have types. A weakly typed language has looser typing rules and may produce unpredictable or
In a type system with Gradual typing, variables may be assigned a type either at compile-time (which is static typing), or at run-time (which is dynamic typing). This allows software developers to choose either type paradigm as appropriate, from within a single language. [26]

What is gradual typing?
Gradual typing is a type system in which some variables and expressions may be given types and the correctness of the typing is checked at compile time (which is static typing) and some expressions may be left untyped and eventual type errors are reported at runtime (which is dynamic typing ).
As a lot of dynamic languages come with a dynamic type system, runtime inference of types based on values for internal interpretation marks a common task. As value types may change throughout interpretation, it is regularly used upon performing atomic operations.
Chu Bong-Foo invented a common input method in 1976 with his Cangjie input method, which assigns different "roots" to each key on a standard computer keyboard. With this method, for example, the character 日 is assigned to the A key, and 月 is assigned to B. Typing them together will result in the character 明 ("bright").
Dynamic checking means that type errors are reported based on a program's dynamic (run-time) behavior. Notes. ^ Unsafe operations are well isolated by a "Unchecked_" prefix. ^ with optional dynamic type casting (see dynamic cast) ^ a b c d e f It is almost safe, unsafe features are not commonly used.
Dynamic typing, also called latent typing, determines the type-safety of operations at run time; in other words, types are associated with run-time values rather than textual expressions. [71] As with type-inferred languages, dynamically-typed languages do not require the programmer to write explicit type annotations on expressions.
