Python uses the name “function” to describe a reusable chunk of code. Other programming languages use names such as “procedure,”“subroutine,” and “method.” When a function is part of a Python class, it‘s known as a “method.”. You’ll learn all about Python’s classes and me...

Example 7.3 (code_chunkex.py): Figure 7.3: Example of a Simple Regular Expression Based NP Chunker. Tag Patterns 标签 The rules that make up a chunk grammar use tag patterns to describe sequences of tagged words. A tag pattern is a sequence of part-of-speech tags delimited using angle...

In Python, an object is a chunk of data that contains at least the following: A type that defines what it can do (see the next section) A unique id to distinguish it from other objects A value consistent with its type A reference count that tracks how often this object is used The ...
To keep code legible and consistent, I suggest minimizing the chunk of code contained within JS, keeping most of the logic within RapydScript itself. For example, instead of accessing a variable that shares reserved keyword as JS('module.exports') use JS('module').exports. This will make ...
