[sympy] Best practices for Python 2/3 single codebase?

2013-08-17 Thread Rathmann
Now that we are on a single code base, I have a few questions on how best to write/test code going forward. In particular, do we have a convention on how to handle name changes? One approach might be to have Sympy's code base reflect one of Python 2/3s names/syntax, and adjust as best we can for

Thanks. I wouldn't worry too much about the things that Travis already tests. Is there an easy way to be notified about test failures? Aaron Meurer On Sat, Aug 17, 2013 at 4:02 PM, Matthew Brett wrote: > Hi, > > On Fri, Aug 16, 2013 at 10:15 AM, Jason Moore wrote: >> Sounds good to me. I can w

[sympy] How to extract a general term from a summation expression ?

2013-08-17 Thread echelon3 . nsa94
Hi everyone, I'm trying to solve linear ODEs, using the Frobenius method (ie. with power series). The idea is to obtain a_n in a summation with the following form : y_n(x) = Sum(a_n, (n, 0, oo)) I guess such a mehod already exist but I didn't manage to find it. Thanks in advance -- Y

To pull apart expressions in general in SymPy, use .args, like >>> Sum(f(x), (x, 0, oo)).args (f(x), (x, 0, ∞)) >>> Sum(f(x), (x, 0, oo)).args[0] f(x) See http://docs.sympy.org/0.7.3/tutorial/manipulation.html. Aaron Meurer On Sat, Aug 17, 2013 at 5:04 PM, wrote: > Hi everyone, > > I'm tryin
