I'm coming from Groovy and it has a nice @ToString annotation that you can add before any class that uses reflection to generate a ToString () method 在python中， str () 方法 类似于其他语言中的 toString () 方法。它被称为传递对象作为参数转换为字符串。它在内部调用参数对象的 __str__ () 方法来获取其字符串表示形式。 但是，在这 The toString () method of the Object class returns the string representation of an object. It is called passing the object to convert to a string as a parameter. Class is a user-defined prototype from which objects are created. This allows the child class to provide its own implementation while Python Classes: The basic idea behind an object-oriented language (OOP) is to combine into a single unit both data and associated procedures (known as methods) that operate on the data.
