In general, a function takes arguments (if any), performs some operations, and returns a value (or object). The value that a function returns to the caller is generally known as the function’s return value. All Python functions have a return value, either explicit or implicit. You’ll ...
Part-of-speech tagging is the process of assigning a POS tag to each token depending on its usage in the sentence. POS tags are useful for assigning a syntactic category like noun or verb to each word. In spaCy, POS tags are available as an attribute on the Token object: Python >>>...
bool使用__bool__方法,对于零大小的Vector2d返回False,否则返回True。 Vector2d来自示例 11-1,在vector2d_v0.py中实现(示例 11-2)。 该代码基于示例 1-2,除了+和*操作的方法,我们稍后会看到在第十六章中。 我们将添加==方法,因为它对于测试很有用。 到目前为止,Vector2d使用了几个特殊方法来提供 Pythonist...

6. OOPS in Python From its early beginning, Python has been an object-oriented language. Object-oriented programming (OOP) is a programming technique that emphasizes the usage of classes and objects. Its goal is to use programming to create real-world concepts like inheritance, polymorphisms, and...
