Hi, While trying to set up Travis testing for Python 3 and sympy, I noticed that there does not seem to be a current python3-sympy for Ubuntu 12.04, and that easy_install fails with a python 3 syntax error. Testing an sdist archive from the 0.7.2 branch: python setup.py sdist workon python32 #

I also wanted to comment on this, and I'm glad you brought it to the list. There are several advantages to having things in SymPy even if they already exist in Sage, not just group theory but all aspects of a computer algebra system. First, as David noted, it will be implemented in pure Python.

Hello all, As a high school student, I am encouraged to conduct a science fair experiment each year. I became interested in contributing to SymPy through the 2011 Google Code-In project, and for this year, I am interested in somehow working on SymPy for science fair. I reviewed the GSoC 2012

That looks like it would work. This is our .travis.yml: https://github.com/sympy/sympy/blob/master/.travis.yml. **Hopefully** when we release, pip install sympy and pip-3.2 install sympy (or whatever the Python 3 pip binary is called) should just work. I say hopefully because pip likes to do

We would not want to add an entire natural language processing toolkit; SymPy has a rather strict no external dependencies policy because it needs to be installable in installer-unfriendly environments (non-administrator accounts, mobile devices). However, it would be extremely useful if we

Alright, thanks for that other thread. I'll review this and discuss with my teacher to come up with a more specific plan. The tokenize module is quite interesting - I guess how Gamma would eventually work is to try to process non-Python syntax but also accept Python expressions? Or perhaps
