Pardon my extremely ignorant newbie questions.
Where can I go to find more information about the "self" argument?
Is there something special about the word "self" or did Mr. Guido van
Rossum just decide to us the word arbitrarily?
More precisely it seems that most all classes have "self" as the first
parameter. This may be directly obvious but is the word "self" always
referring to the class or the function it is used in?

I think it would be cool if you could refer to instance variables
without prefixing with "self." I know noone else thinks like me so
Python will never be changed, but maybe you can already do it with
Python today?
..import sys
..
..def magic():
.. s = ""
.. for var in sys._getframe(1).f_locals.__dict__:

Hi,
i was just wondering about the need to put "self" as the first
parameter in every method a class has because, if it's always needed,
why the obligation to write it? couldn't it be implicit?
Or is it a special reason for this being this way?
Thanks.

OK, I'm a newbie...
I'm trying to learn Python & have had fun with it so far. But I'm having
trouble following the many code examples with the object "self." Can
someone explain this usage in plain english?
Thanks,
Wayne

Hi all,
For some reason this bind is calling the donothing function, like it
should, but is then allowing the text to be inserted into the Text
widget.
Here is the code:
self.framebody.tag_config("name", underline=1)
self.framebody.tag_bind("name", "<Any-KeyPress>", self.donothing)

Hi,
I found one example which defines the addition of two vectors as a
method of a class. It looks like that:
class Vector:
def __add__(self, other):
data =
for j in range(len(self.data)):
data.append(self.data + other.data)

I first learned about OO from Java.
I much prefer to program in Python though.
However I am consufed about 2 things.
1. Why do I have to pass self into every method in a class? Since I am
always doing why cant this be automated or abstracted away?
Are the instances where I won't pass self?
I imagine there is some tradeoff involved otherwise it would have been

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
