Strong and weak typing systems determine how strictly a language adheres to operations between different data types, with strong systems requiring explicit conversions and weak systems being more permissive, impacting error frequency and debugging complexity. ...
but the time you don't spend hunting bugs is time you can spend doing something else." When I asked Josh Bloch about strong and weak typing, he said, "It's always beneficial to detect programming errors as quickly as possible.
Incidentally, please be wary of the terms "strong" and "weak" typing, because they don't have a universally agreed technical meaning.相比之下, static typing means that programs are checked before being executed, and a program might be rejected before it starts. Dynamic typing means that the ...
Historically, "strong typing" has been associated with static typing. Languages noted for strong typing include Pascal and Ada; languages noted for weak typing (most notoriously BASIC) had primarily dynamic typing. But the language thatoughtto be most notorious for weak typing has static typing: C...
Python是一种弱类型语言吗?因为变量可以切换类型。 pythonstrong-typingweak-typing 15 据我理解,以下的写法在PHP中是被允许的,因为PHP是一种弱类型语言。 $var = 'Hello'; $var = 5; 我刚刚安装了一个Windows版本的Python 2.6,我本来以为它不会让我像那样轻易地改变类型,但是上面代码的Python等效代码就像PHP...
Weak vs. Strong typing Yes, I know already what you've been thinking, but this post isn't about programming languages. It's about search. We live today in an ocean of information. Too much information we can ever cope for. But, in some sense this information is strongly-typed: things...
20080330 - strong-typing and weak-typing 要注意是强类型和弱类型,很多人容易将此与静态语言和动态语言的混淆。静态语言在编译时检查变量类型,动态语言在运行时检查变量类型。但这不是强类型和弱类型的区别。 弱类型语言允许将一块内存看做多种类型。比如直接将整型变量与字符变量相加。C and C++ 是静态语言,也...
Typing strength is a continuum;MLis more strongly typed thanJava, which is more strongly typed thanC. Strong or weak typing is independent of the choice betweenstatic typinganddynamic typing. Among strongly typed languages,Ada,Java,HaskellandMLare statically typed, whereasPythonandRubyare dynamically...

There's two dimensions when it comes to typing in a language. - First one is the weak vs. strong dimension. - Second one is the static vs. dynamic dimension. Weak vs. strong, in my understanding, is how specific a type needs to be, and how easily it can be implicitly converted or...
