Hi,
I am trying to understand the coercion model...
In the followiing, C is a parent that I defined, in which (I think) I
implemented a coercion map from P to C, but not from ZZ to C.
sage: P
Multivariate Polynomial Ring in x, y over Finite Field in a of size
2^4
sage: C.has_coerce_map_from(P)
Of these two examples:
m(x)=mod(x,10)
m=lambda x:mod(x,10)
The first returns an error unable to convert x (=x) to an integer.
Can anyone explain what's going on here?
Thanks,
Alasdair

Hello!
I need to operate on a statistical data in the sage notebook. But
before I do that I need to get this data from the Oracle DB. Is there
a way to get data from DB?
Cann't find the answer manually :( Any help would be appreciated.

You should define a Python function
def m(x):
return mod(x,10)

Ok. '_populate_coercion_lists_ ' solve my problem.

I am trying to add some stat functions to my API, since Sage does not

The example you showed attempted to call a module, so it was sure to
fail. We cannot guess why
I don't what else I can say. Look at the articles about.

I'm not sure what you meant; are you saying that Kevin's suggestion
does not work? I.e. something like:
import scipy.stats as S
def Mean_(exp1):
v=[RDF(x) for x in list(exp1)]
R1=S.mean(v)
return R1
Which works for me in the following way:
sage: Mean_('1234')

Yes, it seems so.
