New issue 1529 by zhangxiaopan: Not working in Python 3.0, after  
installation, 'import sympy' gives error.
http://code.google.com/p/sympy/issues/detail?id=1529

My computer is "Windows Vista Home Basic"

I installed Python 3.1
I then installed the sympy-0.6.4-win32
I then opened the "IDLE" window.
I then typed 'import sympy', python gives the following error:

Traceback (most recent call last):
   File "<pyshell#0>", line 1, in <module>
     import sympy
   File "C:\Python31\lib\site-packages\sympy\__init__.py", line 23, in  
<module>
     from sympy.core import *
   File "C:\Python31\lib\site-packages\sympy\core\__init__.py", line 21
     exec '%s = _cls()' % (_n)
                      ^
SyntaxError: invalid syntax


I guess the reason is that 'exec' is no more a statement in Python 3 any
more, BTW, even after changing this to exec(), there are still many import
errors about not being able to find modules.
