New issue 1743 by asmeurer: Vectorize subs and make a dummy function for it http://code.google.com/p/sympy/issues/detail?id=1743 The following should work: In [8]: s = x*pi In [9]: s.subs(x, range(10)) --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /Users/aaronmeurer/Documents/Python/sympy/sympy/<ipython console> in <module>() /Users/aaronmeurer/Documents/Python/sympy/sympy/sympy/core/basic.pyc in subs(self, *args) 1079 elif len(args) == 2: 1080 old, new = args -> 1081 return self._subs_old_new(old, new) 1082 else: 1083 raise TypeError("subs accepts either 1 or 2 arguments") /Users/aaronmeurer/Documents/Python/sympy/sympy/sympy/core/cache.pyc in wrapper(*args, **kw_args) 80 k = args 81 try: ---> 82 return func_cache_it_cache[k] 83 except KeyError: 84 pass TypeError: unhashable type: 'list' It is easy to vectorize a function, just add the decorator to the top of the function def, like with expand(). Also, do you think we should have a dummy function subs() that calls the subs method, like we do with N() for evalf? In [10]: subs(s, {x:12}) --------------------------------------------------------------------------- NameError Traceback (most recent call last) /Users/aaronmeurer/Documents/Python/sympy/sympy/<ipython console> in <module>() NameError: name 'subs' is not defined -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
