The object() function returns an empty object. You cannot add new properties or methods to this object. This object is the base for all classes, it holds the built-in properties and methods which are default for all classes.
A Java object is a member (also called an instance) of a Java class. Each object has an identity, a behavior and a state. The state of an object is stored in fields (variables), while methods (functions) display the object's behavior. Objects are created at runtime from templates, which are also known as classes.
Benefits of Object ModelIt helps in faster development of software. It is easy to maintain. Suppose a module develops an error, then a programmer can fix that particular module, while the other parts of the software are still up and running. It supports relatively hassle-free upgrades.
The advantages of using object literals to create objects include convenience, flexibility in declaration, and less code during declaration. You can drop an object literal anywhere in your program with no previous setup and it'll work, which can be very handy!
How is it possible that
class EmptyClass:
def __init__(self):
pass
e = EmptyClass()
e.a = 123
works and:
o = object()
o.a = 123
does not (AttributeError: 'object' object has no attribute 'a') while
print isinstance(e, object)
>>> True
?
What is object() good for then, when you cannot use it like this?
