The 2to3 code converts sympy just fine, but then one needs to apply this patch:
----------------------------- sympy/core/logic.py -----------------------------
index d3ae4ec..293f947 100644
@@ -66,6 +66,16 @@ def __ne__(a, b):
else:
return a.args != b.args
+ def __lt__(cls, other):
+ if cls.__cmp__(other)==-1:
+ return True
+ return False
+
+ def __gt__(cls, other):
+ if cls.__cmp__(other)==1:
+ return True
+ return False
+
def __cmp__(a, b):
if type(a) is not type(b):
and then fix the imports in sympy/core. Then it could start working.
The way to fix the imports is to just use regular "import something"
syntax, but do not inject things into other modules, because python3.0 is
more strict and this doesn't work.

running with python2.6's -3 flag output's some useful warnings. |

Another thing that will have to change is that Python 3 does not support cmp functions for sorting anymore. You have to use a key function. I know at least Basic._compare_pretty() and compare_ode_sol() in ode.py are cmp functions, but I am sure there are others. |

Using the -3 switch (e.g. "python -3 bin/test") is a good way to check what has to be done. The real problems are sorting with a cmp instead of a key, and overriding __eq__ or __cmp__ without overriding __hash__. |
