New issue 3441 by [email protected]: _kern leftover from sympify of a list http://code.google.com/p/sympy/issues/detail?id=3441 This was sent to me by email: The sympify function uses inner "_kern" symbol in order to do some things smartly. At the end, all occurences of the symbol should be replaced by "1". But the replacement uses "in" statemtent, that is not valid when the result of sympify is a structure (e.g. a list): from sympy import sympify for xpr in ('[-(2/4)]', '[-2/4]', '-(2/4)', '-2/4'): print(sympify(xpr)) # the response is ''' [-_kern/2] [-1/2] -1/2 -1/2 ''' -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
