I am wondering whether it is possible to add fields to objects dynamically. For example, I want to be able to add something like:
user = object()
user.first_name = 'John'
user.last_name = 'Smith'
When I execute that in Python command line interpretor I get:
AttributeError: 'object' object has no attribute 'first_name'
Any idea?
Try this:
class Object:
pass
obj = Object()
obj.x = 5
pass: docs.python.org/tutorial/controlflow.html#pass-statements 2) No, when you do obj.x = 5, you only add x attribute to single instance of Object. If you want all Object instances to share x, you have to do Object.x = 5.
None. Objects created in the way gruszczy proposes do not have any kind of "prototype"; you can add and delete attributes at will, and it has no effect on any other instance of the Object class.
You cannot assign to attributes of object instances like this. Derive from object, and use an instance of that class.
