Hi Thomas,

ipython-user is deprecated, you should post on ipython-dev, even if the
name is misleading. All mail traffic is going through that now.

Cheers,

i everyone,<br>
<br>
(apologies if you already saw this on the numpy-discussion list. I am<br>
resending it to the scipy-user and ipython-user mailing lists since<br>
these were down last week)<br>
<br>
We have released a small experimental package called numtraits that<br>
builds on top of the traitlets package and provides a NumericalTrait<br>
class that can be used to validate properties such as:<br>
<br>
* number of dimension (for arrays)<br>
* shape (for arrays)<br>
* domain (e.g. positive, negative, range of values)<br>
* units (with support for astropy.units, pint, and quantities)<br>
<br>
The idea is to be able to write a class like:<br>
<br>
=C2=A0 =C2=A0 class Sphere(HasTraits):<br>
<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0 radius =3D NumericalTrait(domain=3D&#39;strictl=
y-positive&#39;, ndim=3D0)<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0 position =3D NumericalTrait(shape=3D(3,))<br>
<br>
and all the validation will then be done automatically when the user<br>
sets &#39;radius&#39; or &#39;position&#39;.<br>
<br>
In addition, tuples and lists can get automatically converted to<br>
arrays, and default values can be specified. You can read more about<br>
the package and see examples of it in use here:<br>
<br>
=C2=A0 <a href=3D"https://github.com/astrofrog/numtraits" rel=3D"noreferrer=
" target=3D"_blank">https://github.com/astrofrog/numtraits</a><br>
<br>
and it can be easily installed with<br>
<br>
=C2=A0 pip install numtraits<br>
<br>
The package supports both Python 3.3+ and Legacy Python (2.7) :)<br>
<br>
At this point, we would be very interested in feedback - the package<br>
is still very young and we can still change the API if needed. Please<br>
open issues with suggestions!<br>
<br>
Cheers,<br>
<br>
Tom and Francesco<br>
