Hello!
Always when I use "super" I create a code duplication because class
used as first arg to "super" is always the class where the method
containing "super" was defined in:
'''
class C:
def method(self):
super(C, self).method()
'''

Hi,
I hope this is not a FAQ, but I have trouble understanding the behaviour of
the super() built-in function. I've read the excellent book 'Python in a
Nutshell' which explains this built-in function on pages 89-90. Based on the
example on page 90, I wrote this test code :
class A(object):
def test(self):
print 'A'

I've been to the cookbook (both forms, since they're sometimes usefully
different), but that gave rise to more questions than answers. Heck,
let me pull some of them up while I'm at it.
Martelli gives the recipie (5.3 on paper) "Calling a Superclass
__init__ Method if it Exists" where he seems to say that this:
class NewStyleOnly(A, B, C):
def __init__(self):
super(NewStyleOnly, self).__init__()

So when I'm writing a class and I define an __init__ method, I sometimes
haven't called object.__init__, e.g.:
class C(object):
def __init__(self, x):
self.x = x
instead of
class C(object):

Hello!
Im working with new (object) classes and normaly call init of ther
motherclass with callin super(...), workes fine.
No, I've got a case with multiple inherance and want to ask if this is
the right and common case to call init:
class Mother(object):
def __init__(self, param_mother): print 'Mother'

Hi,
I was wondering whether someone could shed some light on the following.
Using inheritance in Java one can override a function f() (or is it
overload?) in the child and then do:
public f() {
super.f();
...
}
in the child to first execute the parent stuff to be followed by the

Hi
I have a a function with several methods. For simplicity it looks a bit
like this:

super.prototype.returnValue = function () {

I'm reading Alex Martelli's "Nutshell" second edition. In the section
called "Cooperative superclass method calling", he presents a diamond
inheritance hierachy:
class A(object):
def met(self):
print "A.met"
class B(A):
def met(self):
print "B.met"

Hello, I have been trying to call the super constructor from my
derived class but its not working as expected. See the code:
class HTMLMain:
def __init__(self):
self.text = "<HTML><BODY>";
print(self.text);
def __del__(self):
self.text = "</BODY></HTML>";
print(self.text);

Hi All,
Now that I am really diving into Python, I encounter a lot of things
that us newbies find difficult to get right. I thought I understood
how super() worked, but with 'private' members it does not seem to
work. For example;
.... def __baseMethod(self):
.... print 'Test'

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

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...
