I want to know why Python is not fully object-oriented. For example, it does not support private, public, protected access level modifiers.
What are the advantages and disadvantages of this? By these expressions, Python is suitable for what applications (Desktop, Scientific, Web or other)?
What exactly is full object oriented?  Alan Kay said "Actually I made up the term "object-oriented", and I can tell you I did not have C++ in mind.".  Admittedly, he probably did not have python in mind either, but it is worth noting that Smalltalk also protects classes by convention, no mandate.
