ML语言采用的是所谓Binding Statement, 而不是其他语言中常见的assignment statement。这意味着ML语言中的变量有着 immutable 的性质。 syntax: valx=e; Function Bindings syntax: funx0(x1 :t1, x2 :t2, ..., xn :tn)= e 当对一个 Function binding 进行 type-checking 时,使用 current static environment...

Foundations using R specialization. It teaches learners to build models, make inferences, and deliver interactive data products. There are five courses in the specialization each of which includes a hands-on, peer-graded assignment. There is also a capstone project where learners build a data produ...
which we use to determine dependencies between input variables and outputs. We finalize with a collection of metrics to measure model accuracy, and continue with the introduction to the Python programming language. Please note, there is no formal assignment this week, and we hope that everyone par...
Bindings are immutable. Given val x = 8+9; we produce a dynamic environment where x maps to 17. In this environment, x will always map to 17; there is no “assignment statement” in ML for changing what x maps to. That is very useful if you are using x. You can have another bin...
通过constructor 我们可以构造 mytype 类型的值。如 TwoInts(1, 2), Str"hi", Pizza。 对于同样是 one-of type 的 option 来说,通过isSome : option -> bool函数可以判断 variant 类型 (NONE or SOME),valOf : t option -> t可以取出 SOME 中的值。而如果是自己定义的 datatype ML 语言并不提供这...
