I think this is a very defendible position too. Isn't it frustrating when you look at an example, and it has all kinds of hidden assumptions, so copy/paste of it doesn't "just work". For example, in numpy docs, one often sees the implicit assumption that one did "import numpy as np" or "from numpy import *". -- William > > If you want to make it so that you don't have to import your file you > can put it somewhere in the sage directory and then add an entry for > it in the all.py file that resides in the same folder as your file. > > -Jim > > On Tue, Feb 21, 2012 at 8:16 AM, Laurent <moky.m...@gmail.com> wrote: >> >>>> On 21 Feb., 14:24, Laurent<moky.m...@gmail.com> wrote: >>>>> >>>>> Is it normal ?
