Comment #5 on issue 1719 by ronan.l...@gmail.com: implement from sympy.abc import lower, greek http://code.google.com/p/sympy/issues/detail?id=1719
In from sympy.abc import ..., you are following a file path: python fetches the module abc.py inside sympy/. On the other hand, sympy.abc is the attribute named 'abc' of the module object sympy. Since abc is never imported in sympy/__init__.py, this is not defined. These 2 lines at the end of sympy/__init__.py give some sort of explanation: # This is slow to import: #import abc -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
