This Learning Path shows you how to leverage the power of both native and third-party Python libraries for building robust and responsive applications. You will learn about profilers and reactive programming, concurrency and parallelism, as well as tools
As of today, Numba doesn't support optimization of generic Python objects. This limitation, however, doesn't have a huge impact on numerical codes as they usually involve arrays and math operations exclusively. Nevertheless, certain data structures are much more naturally implemented using objects; ...

Pure Python Optimizations As mentioned in the last chapter, one of the most effective ways of improving the performance of applications is through the use of better algorithms and data structures. The Python standard library provides a large variety of ready-to-use algorithms and data structures th...
将class序列化必须先把class对象转化为dict,然后python才能把dict转化为JSON,dumps()方法的default参数可以把任意一个对象变成一个可序列为JSON的对像。 1importjson23classStudent(object):#建立一个类4def__init__(self, name, age, score):5self.name =name6self.age =age7self.score =score89defstudent2di...
python advanced programming ( II ) 面向对象编程 简称OOP,是一种程序设计思想。OOP把对象作为程序的基本单元,一个对象包含了数据和操作数据的函数。数据封装、继承和多态是面向对象的三大特点。 在Python中,所有数据类型都可以视为对象,当然也可以自定义对象。自定义的对象数据类型就是...
Another important feature available in Python regarding generators is the ability to interact with the code called with the next function. yield becomes an expression, and a value can be passed along with a new method called send: def psychologist(): print('Please tell me your problems') while...
