between various input languages and then interpreting them as Python
(Python, TeX, English-like, etc.) could also be an interesting task.
Heh. That's simple:
- Have a grammar for each syntax that we have,
-
Another thing you could look at is what should be done at the parsing
stage and what should be done after the parsing. For example, 2 x,
x y, and tan x are all the same syntax as far as the parser is
concerned (unless you want to put all predefined names in the grammar
itself), but the first two
Okay, some bad news - this might not qualify as a science fair project
since it doesn't really have an experiment. My teacher will double-check,
but he wasn't too sure. However, I would still like to pursue this project
as it interests me.

Yes, what I was thinking is that there would be a whitespace expansion
step (probably after tokenization) that would convert statements like 2xy
into 2 x y and then tokenize again
Multiple tokenization steps are usually not worth it.
Make it so that
Alright, that seems like a good approach. Actually, playing around with the
parser, it already seems to parse (but won't evaluate) expressions like 2x:
if I add a print statement to show the final list of tokens,
sympy.parsing.sympy_parser.parse_expr(2 x y)
[(1, 'Integer'), (51, '('), (2,
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

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
