numbers——数字抽象基类,其源代码存储在:Lib/numbers.py numbers模块定义了数字抽象基类的层次结构,逐渐定义更多的操作。该模块中定义的任何类型都不能实例化。 1.数字塔 class numbers.Complex 数字的一个子类,用来描述复数以及可应用于内置复数类型的操作中。它们是:complex(复数)转化、bool(布尔)、real(复数实部)...

This way, Python knows that the iteration has reached its end. By implementing these two methods in your custom classes, you’ll turn them into iterators. For example, say you want to create a class that provides an iterator over the numbers in the Fibonacci sequence. In that situation, ...
The __add__ method is used to implement addition operation. In Python, numbers are not primitive literals but objects. The num + 4 expression is equivalent to num.__add__(4). main.py #!/usr/bin/python class MyDict(dict): def __add__(self, other): self.update(other) return My...
The __mul__ magic method in Python is used to multiply two numbers. However, it can also be used to create a number with a decimal point in it. This can cause problems when working with numbers that are stored in a database or other data storage system. ...
