Hello All,
I'm reading Learning Python's section 'Operator Overloading' and I was
wondering why
class headers that implement and overload are lowercase?
Cheers,

I'm not sure what you mean by class headers?
Can you post an example?

As for my question it looks like the convention is if a class only has
operator overloading then the class receives a lowercase class name.
If the class has a mix, operator overloading and a normal method then
the class name gets sta

Thanks Hugo,
Do methods like __add__, __del__, count as built-in types? I'm aware of the
rule you explained and use it and that's why when I saw:
class indexer():
def ___getitem__(self, index):
return index ** 2
I thought I was missing some special style, or rule. The class above i

Built-in types are only those classes 'built in' to the python

Hmm, that's pretty dubious usage of header in my view.
Its the class definition and there is nothing "header" about it.

Hi,
For class definitions I've always used
class Knights:
but I've just seen an example using:
class Knights(object):
So I did a quick little test and see this:
>>> a = Knights()
>>> b = Knights2()
>>> a
<__main__.Knights instance at 0xb7e12bec>
>>> b
<__main__.Knights2 object at 0xb7e12b2c>

Python is a programming language, not a printer driver.
So this is not the best place to ask the question.
