Hi,
I want to point out first of all that I'm not as familiar with Python as
I should be, and for that reason I question a lot of things because I'm
mainly a C++ programmer and I'm used to certain conveniences. Having
said that...
I've always been curious (more so than annoyed) as to why one must
explicitly specify a "self" parameter for member functions in a class in
Python. This seems very "C" like to me, since to do object oriented
programming in C you must devote one parameter to the object itself. In
a higher order language like Python, I would not have expected (and thus
am rather surprised) that this pattern would apply. Is there any
particular reason why 'self' parameters must be specified explicitly? I
am curious to understand the philosophy and design behind this.
In Python 3 will there be any plans to eliminate this syntactic
artifact? As I said, it's not terribly annoying to me but it seems like
more of a hack than anything else. I would feel a bit better if I didn't
have to see it. I don't mean to start any syntax wars or anything, so I
hope everyone will keep an open mind and simply explain the design,
rather than defend it. I'm interested in only facts, and not opinions.
This is an example of a response I'm looking for:
"The self parameter is required because the parser is a bit old and
needs to know the exact object you're referencing"
This is _not_ an example of what I'm looking for:
"Specifying self is a great mysterious thing that we should never
question. Do not question the language! The language is mighty! Don't
bring C++ to Python!"
I appreciate the community's time.

There was a massive thread "attack a sacred python cow" that brought up
a lot of reasons why this is the case. If you can ignore the flames,
you'll find some good info there. But it might not be wise to bring it
up again a week after it happened last time.
