I myself prefer to import everything by hand in Python. Thus the sage module can have many things (even all letters) preloaded, because there cannot be any confusion -- I want to use it like this: from sage import e, I, sin, x print I*sin(x) and actually even the "x" is kind of confusing, in SymPy we need to create it by hand, like "x=Symbol('x')". Then there can be some very limited environment, that imports some things automatically, for example "isympy" (which is just ipython) in our project does from sympy import * x = Symbol("x") y = Symbol("y") z = Symbol("z") at the beginning automatically, so that one can use it interactively. But for any serious working, I prefer to do it by hand from my own script. Like any other python library.
