Re: [sympy] Re: Google+ Hangouts

The time zone issue is relevant no matter what realtime medium is used. We've always been able to work around it. People sleep for eight hours and are awake for 16 hours, so there is always overlap in awake time. At worst one party may have to wake up early or stay up late to make it work. Aaron

[sympy] auto_update_dict in subs

I wrote a class (see below) for a automatically updating dictionary. For example let - def xsq(x): return(x*x) D = auto_update_dict(xsq) D[2] calls xsq and returns 4 call D[2] and xsq is not called since the previous call has called xsq and placed the result in the dictionary. Again 4

Re: [sympy] auto_update_dict in subs

I suppose subs should be changed to just iterate over the entries. Another option would be to create an object that implements __iter__ that returns (old, new) pairs. Does subs do this just for simplicity, or does it need to have all the pairs at once before it can do the substitution? Aaron

Re: [sympy] auto_update_dict in subs

When you give a dictionary the keys are unordered and to be canonical, the keys are sorted. What sort of expression are you wanting to do what type of substitution on? Maybe replace, xreplace or Transform are better matches for what you want to do. -- You received this message because you are
