I may be reading this question different than Fredrik.
This example is with old-style classes.
class baseclass:
def __init__(self, arg):
#
# Do some initialization
#
def method1(self, arg):
#
# baseclass method goes here
#
class myclass(basecla ss):
def __init__(self, arg):
#
# This method gets called when I instantiate this class.
# If I want to call the baseclass.__ini t__ method I must
# do it myself.
#
baseclass.__ini t__(arg)
def method1(self, arg):
#
# This method would replace method1 in the baseclass
# in this instance of the class.
#
myObj=myclass(a rg)
I could be way off base, but maybe it will help.

This is an example of polymorphism generally, not overloading.

it looks like you're using a non-standard definition of the word "overloadin g".
here are the usual definitions (quoting from a random google page):
"Overloadin g a method refers to having two methods which share the
same name but have different signatures."
"Overriding a method refers to having a new implementation of a method
with the same signature in a subclass."

to programming after a gap of about ten years I've really enjoyed

I've just made my first forays into inheritance and operator

I've written a simple config file parser - and I thought I'd

Hello all,
Is there a common way to emulate constructor overloading in Python class?
For instanse, I have 3 classes:
1/ Polar - to hold polar coordinates;
2/ Cartesian - to hold cartesian coordinates;
3/ Coordinates3D, which holds synchronized instances of the both in
__p__ and __c__ fields respectively.

Hi All,
I've seen lots of code in which the attributes of a class are accessed and
modified using two separate methods. For example:
class Problems:
def __init__( self, refNum ):
self._refNum = refNum
self._title = ""
self._problem = ""

Python allows the binding behaviour to be defined for descriptors,
using the __set__ and __get__ methods. I think it would be a major
advantage if this could be generalized to any object, by allowing the
assignment operator (=) to be overloaded.
One particular use for this would be to implement "lazy evaluation".
For example it would allow us to get rid of all the temporary arrays
produced by NumPy.
For example, consider the...

Working on a class that I would use multiple constructors in C++ since I have different ways of creating the data. Tried this in python by defining multiple __init__ methods but to no avail, it seems to only find the second one. So I have:

self.name = mystring1
self.value = mystring2
