The decision of when to implicitly intern a string is implementation-dependent. There are some rules that can be used to guess if a string will be interned or not: All length 0 and length 1 strings are interned. Strings are interned at compile time ('wtf' will be interned but ''....

- 类由关键字class创建。 - 属性是属于类的变量。 - 属性始终是公共的,可以使用点(.)操作。例如:Myclass.Myattribute 类定义语法: class ClassName: # Statement-1 # Statement-N 在Python中创建空类 class Dog: pass 在上面的例子中,我们使用class关键字创建了一个名为Dog的类。
