I`m starting to learn python, and I hava a very good background in Java
and C/C++ programming. I was reading Dive into python chapter about
OO and I saw that in python we can do the following:
class Person:
pass
joe = new Person()
joe.name = "Joe"
joe.age = 13
It seems that it is possible to add attributes to any object instance
in run time, as in _javascript_. It seems to me that it can be a source
of errors. One that come in my mind is the follwing:
class Person:
name = ""
joe = new Person()
joe.nome = "Joe"
The code above adds an attribute called nome, but the programmer may think it's name.
What is the real interest of this feature ? Is there a way to block this kind of error ?
Thanks,
Miguel
