That's because this bug in 2to3: http://bugs.python.org/issue5093 Using the workaround it all gets converted, and I pushed my changes to http://fseoane.net/git/sympy.git, branch py3 However, I am getting some problems with string.strip() when importing sympy: >>> import sympy Traceback (most recent call last): File "<stdin>", line 1, in <module> File "sympy/__init__.py", line 23, in <module> from sympy.core import * File "sympy/core/__init__.py", line 4, in <module> from .basic import Basic, S, C, sympify File "sympy/core/basic.py", line 3, in <module> import sympy.mpmath as mpmath File "sympy/mpmath/__init__.py", line 3, in <module> from .mptypes import ( File "sympy/mpmath/mptypes.py", line 40, in <module> from string import strip ImportError: cannot import name strip I suppose we should be using string.format or something similar, http://docs.python.org/3.1/library/string.html > > Ondrej > > > > -- http://fseoane.net/blog/ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
