Static variables are easy to access. Static variables are helpful to increase the readability of the code. Static variables are useful to unitize class-related variables. Since they are initialized once in the class, it is flexible to initialize and modify the data.Disadvantages...
Class variables are defined within theclass construction. Because they are owned by the class itself, class variables are shared by all instances of the class. They therefore will generally have the same value for every instance unless you are using the class variable to initialize a variable. D...

They just were built-in variables, and it was possible to reassign them Python 3 was backward-incompatible, the issue was finally fixed, and thus the last snippet won't work with Python 3.x!▶ Class attributes and instance attributes1....
Python不像C++和JAVA等语言,各种class不需要在类体明确声明变量(属性)及函数(方法),因此在使用第三方库的时候,如果帮助文档不完整,就很难通过源代码去查看某个类有哪些属性和方法。在网上查了些资料,并动手实践了下,大致可以通过四种办法来获取某个类/对象的属性及方法。
class Human: # A class attribute. It is shared by all instances of this class # 类属性,可以直接通过Human.species调用,而不需要通过实例 species = "H. sapiens" # Basic initializer, this is called when this class is instantiated. # Note that the double leading and trailing underscores denote ...

Class attributes (your data) are just like variables that exist within object instances. The __init__() method can be defined within a class to initialize object instances. Every method defined in a class must provide self as its first argument. ...
