the following is what I did. I don't have INSTALLed python, because I want to make portable development enviroment, and I hate to write to register. I am using winxp
I dont' find the problem with py2.6.2, I hope it will not be a bug for py2.4.4. 1. download http://www.python.org/ftp/python/2.4.4/python-2.4.4.msi, which is the lastest official bianry release of py 24 for windows 2. use http://legroom.net/software/uniextract to extract python-2.4.4.msi to R:\python-2.4.4 3. downlaod http://sympy.googlecode.com/files/sympy-0.6.4.tar.gz abd extract it into R:\_sympy\, then the real package is at R:\_sympy\sympy \ 4. go to the dosbox 5. set pythonpath= this will clear the enverioment setting 6. here is the code [a.py] import sys sys.path.insert(0, r'r:\_sympy') import sympy print sympy.simplify(sympy.sqrt((-2+sympy.sqrt(2)/2)**2+(2-sympy.sqrt (2)/2)**2)) [/a.py] 7. let's go R:\>r:\python-2.4.4\python.exe a.py -1 + 2*2**(1/2) 8. go again R:\>r:\python-2.4.4\python.exe a.py Traceback (most recent call last): File "a.py", line 4, in ? print sympy.simplify(sympy.sqrt((-2+sympy.sqrt(2)/2)**2+(2- sympy.sqrt(2)/2)* *2)) File "r:\_sympy\sympy\simplify\simplify.py", line 1079, in simplify expr = Poly.cancel(powsimp(expr)) File "r:\_sympy\sympy\polys\polynomial.py", line 605, in cancel numer, denom = f.as_numer_denom() File "r:\_sympy\sympy\core\power.py", line 428, in as_numer_denom num = n ** exp File "r:\_sympy\sympy\core\sympify.py", line 271, in __sympifyit_wrapper return func(a, b) File "r:\_sympy\sympy\core\basic.py", line 668, in __pow__ return Pow(self, other) File "r:\_sympy\sympy\core\cache.py", line 85, in wrapper func_cache_it_cache[k] = r = func(*args, **kw_args) File "r:\_sympy\sympy\core\power.py", line 85, in __new__ obj = a._eval_power(b) File "r:\_sympy\sympy\core\mul.py", line 293, in _eval_power return coeff**e * Mul(*[s**e for s in rest]) File "r:\_sympy\sympy\core\sympify.py", line 271, in __sympifyit_wrapper return func(a, b) File "r:\_sympy\sympy\core\basic.py", line 668, in __pow__ return Pow(self, other) File "r:\_sympy\sympy\core\cache.py", line 85, in wrapper func_cache_it_cache[k] = r = func(*args, **kw_args) File "r:\_sympy\sympy\core\power.py", line 85, in __new__ obj = a._eval_power(b) File "r:\_sympy\sympy\core\power.py", line 104, in _eval_power if self.base.is_nonnegative and self.exp.is_real and other.is_real: File "r:\_sympy\sympy\core\assumptions.py", line 366, in getit return self._what_known_about(name) File "r:\_sympy\sympy\core\assumptions.py", line 279, in _what_known_about a = getattr(self,'is_'+pk) File "r:\_sympy\sympy\core\assumptions.py", line 366, in getit return self._what_known_about(name) File "r:\_sympy\sympy\core\assumptions.py", line 279, in _what_known_about a = getattr(self,'is_'+pk) File "r:\_sympy\sympy\core\assumptions.py", line 366, in getit return self._what_known_about(name) File "r:\_sympy\sympy\core\assumptions.py", line 296, in _what_known_about v = self.evalf() File "r:\_sympy\sympy\core\evalf.py", line 1010, in Basic_evalf result = evalf(x, prec+4, options) File "r:\_sympy\sympy\core\evalf.py", line 950, in evalf r = rf(x, prec, options) File "r:\_sympy\sympy\core\evalf.py", line 296, in evalf_add terms = [evalf(arg, prec+10, options) for arg in args] File "r:\_sympy\sympy\core\evalf.py", line 950, in evalf r = rf(x, prec, options) File "r:\_sympy\sympy\core\evalf.py", line 348, in evalf_mul re, im, a, aim = evalf(arg, prec, options) File "r:\_sympy\sympy\core\evalf.py", line 950, in evalf r = rf(x, prec, options) File "r:\_sympy\sympy\core\evalf.py", line 445, in evalf_pow return mpf_sqrt(xre, prec), None, prec, None File "r:\_sympy\sympy\mpmath\libmpf.py", line 1485, in mpf_sqrt shift += shift & 1 TypeError: unsupported operand type(s) for &: 'float' and 'int' --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
