definition:抽取array的一部分element生成新array。 对Python list进行切片操作得到的array是原始array的transcript,而对Numpy array进行切片操作得到的array则是指向相同buffer的view。 (上述一段话可概括为:Python的list切片会创建transcript,而Numpy的array切片知识创建一个view,它们共享data memory。) ①如果想要抽取array...

in contrast to a statically typed language such as C, because variable names (for example, “x”) can point to objects of any type. For instance, “x” can equal the number 3, but the same variable name can also be assigned the value of the string “car” or the value of the list...

Also, when a data type is used, the whole code needs to be checked for type correctness before the code is executed. The basic definition of an interpreted language is that the full code is not analyzed before execution, so the types cannot be checked. This of course, is my spec...
