When to Use Instance Methods Instance methods are the most common methods in Python classes. You use them when you want to implement functionality that can access and change the state of an instance. Maybe you’
@classmethod means: when this method is called, we pass the class as the first argument instead of the instance of that class (as we normally do with methods). This means you can use the class and its properties inside that method rather than a particular instance. @staticmethod means: whe...
The syntax of classmethod() method is: 1 classmethod(function) classmethod() is considered un-Pythonic so in newer Python versions, you can use the@classmethoddecorator for classmethod definition. classmethod()被认为是非Pythonic,因此在较新的Python版本中,您可以使用@classmethod装饰器进行classmethod定义。

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 ''....
