Almost without exception, class names use the CapWords convention. Classes for internal use have a leading underscore in addition. Exception Names Because exceptions should be classes, the class naming convention applies here. However, you should use the suffix "Error" on your exception names (if ...

classAbelApp(abel):def … Python 中的变量名解析遵循LEGB原则,本地作用域(Local),上一层结构中的def或Lambda的本地作用域(Enclosing),全局作用域(Global),内置作用域(Builtin),按顺序查找。 和变量解析不同,Python 会按照特定的顺序遍历继承树,就是方法解析顺序(Method Resolution Order,MRO)。类都有一个名...
The context object is a Python class that's defined in the Lambda runtime interface client. To return the value of any of the context object properties, use the corresponding method on the context object. For example, the following code snippet assigns the value of the aws_request_id propert...
In this tutorial, you'll compare Python's instance methods, class methods, and static methods. You'll gain an understanding of when and how to use each method type to write clear and maintainable object-oriented code.
