Hi all
I needed something similar to, but not quite the same as,
collections.namedtuple.
The differences are that namedtuple requires the 'names' to be provided at
creation time, and then lends itself to creating multiple instances of
itself. I wanted a more generic class where I could suppl

Sorry, my mistake.
The real problem is this.
When I started working on the package, somehow all of indentations were
made by space-bars instead of using tabs.
But when I am implementing my own on top of it, I still use tabs to make
indentations.
This is causing a problem.

unfortunately, the 3rd party application uses Py2.5.x internally, so I

Thanks for the report. I've released a 2.0.2 version on PyPI. That

Is this by design? It seems to me that this is not the correct

int
Doh!
Well the problem is that int's are integers. So yeah, you can't even do
that with normal value "int ('2.1')" will also throw an error. And
floats don't support radix conversion, because no-one really writes
numbers that way. (At least computer programmers...)

Hi, how can I write the popular C/JAVA syntax in Python?
Java example:
return (a==b) ? 'Yes' : 'No'
My first idea is:
return ('No','Yes')[bool(a==b)]
Is there a more elegant/common python expression for this?

The conversion is not supported for decimal integers AFAIK, however
'0b123.456' is always valid. I guess you can always get a decimal number
convertor onto Python-recipes

I understand there are technical reasons for why math.fsum() exists.

To get the decimal representation of a binary number, I can just do
this:
int('11',2) # returns 3
But decimal binary numbers throw a ValueError:
int('1.1',2) # should return 1.5, throws error instead.
Is this by design? It seems to me that this is not the correct
behavior.

not really, the int will eventually overflow and cycle around ;)
