This might be a duplicate post---I sent something a few minutes ago
but I might not have had a subject line....did not see post come up..
I am teaching a course in using software to do mathematics and have
been discussing Python.
I would like to present this to the class but cannot get to first
base.
I have done some Python programing but never used sympy.
I just today downloaded sympy-0.6.4.
In idle on Windows I get:
Python 3.0.1 (r301:69561, Feb 13 2009, 20:04:18) [MSC v.1500 32 bit
(Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> from sympy import Symbol, cos
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
from sympy import Symbol, cos
File "C:\Python30\lib\site-packages\sympy\__init__.py", line 23, in
<module>
from sympy.core import *
File "C:\Python30\lib\site-packages\sympy\core\__init__.py", line 21
exec '%s = _cls()' % (_n)
^
SyntaxError: invalid syntax
>>>
and very similar result from command line on Windows or in Linux---the
slight difference is where the carat is.
exec '%s = _cls()' % (_n)
