16 How to add property to a python class dynamically? Say you have an object that you want to add a property to. Typically, I want to use properties when I need to begin managing access to an attribute in code that has downstream usage, so that I can maintain a consistent API.
It is NOT 'bad' to use the new keyword. But if you forget it, you will be calling the object constructor as a regular function. If your constructor doesn't check its execution context then it won't notice that 'this' points to different object (ordinarily the global object) instead of the new instance. Therefore your constructor will be adding properties and methods to the global object ...

property 's arguments are getx, setx, delx and a doc string. In the code below property is used as a decorator. The object of it is the x function, but in the code above there is no place for an object function in the arguments.
A property should always encapsulate one or more fields, and should never do any heavy lifting or validation. If you need a property such a UserName or Password to have validation, change their type from strings to Value Objects. There is an unspoken contract between a class-creator and the consumer.
Descriptors like property need to be in the type's dictionary to work their magic. So those in a class definition primarily affect the behaviour of instances of the class, with minimal effect on the behaviour of the class itself (since the class is the type of the instances).

A new expression is the whole phrase that begins with new. So what do you call just the "new" part of it? If it's wrong to call that the new operator, then we should not call "sizeof" the sizeof operator, or & the address-of operator (when it behaves like one).
You should use new when you wish an object to remain in existence until you delete it. If you do not use new then the object will be destroyed when it goes out of scope.
The new operator uses the internal [[Construct]] method, and it basically does the following: Initializes a new native object Sets the internal [[Prototype]] of this object, pointing to the Function prototype property. If the function's prototype property is not an object (a primitive values, such as a Number, String, Boolean, Undefined or Null), Object.prototype is used instead. After ...
