Statically typed programming languages allow earlier errorchecking, better enforcement of diciplined programming styles, and thegeneration of more efficient object code than languages where all typeconsistency checks are performed at run time. However, even instatically typed languages, there is often the...
The objects and libraries implemented in one language can be used by other languages. The DLR also enables interoperation between statically typed and dynamic languages. For example, C# can declare a dynamic object that uses a library that is written in a dynamic language. At the same time, ...
strong does not equal static. As a matter of fact, these type systems are independent of each other. There can be static but weak type system (for example C and C++). Also dynamically, but strongly typed language is possible (for example Ruby and Python). OK, so what’s a strongly ty...
The PythonConsoleHost class is very small. It has a very short Initialize method that sets the LanguageProvider (and therefore the execution engine) to be the IronPython implementation. PythonConsoleHost's Main method simply calls into the default ConsoleHost class provided by...
BETA is a compiled and statically typed object-oriented programming language. The metalevel interface preserves the type safe properties of the language and supports static type checking. This is achieved through a novel language construct, the attribute reference , on top of which the metalevel ...

Kotlin is a compiled, statically typed language, which might provide some initial hurdles for people who are used to the interpreted, dynamically typed Python. This document aims to explain a substantial portion of Kotlin's syntax and concepts in terms of how they compare to corresponding concepts...
脚本语言(Scripting Language)。虽然动态语言通常又被称为脚本语言,但它们也并不完全等价,通常把提供运行时环境(runtime language)的语言叫做脚本语言。 强类型(Strongly typed)和弱类型(Weakly typed)。如果在一种语言里,值的类型不依赖于怎样使用它,那这种语言是强类型,否则是弱类型。比如同样去执行"1" + 2这样...
On the other hand, Python gives you only one chance to set the type of a variable, which makes it more strongly typed. You can dynamically assign the type to a variable and have the runtime infer it from the assigned value. After that, though, you’re not allowed to store any value...
