This will raise SympifyError if there is a syntax error, as you noted.
You can also use parse_expr() if you want more low-level control over

also consider how one would solve eq2 by hand. Should there be a

I think Round as a shortcut for putting parentheses around something

g in numbers are subscripted, so it

Another idea: if A1, B1, and so on are what you want to use as your
symbol names, you can replace "AND" with "&" and "OR" with "|" and the
string will parse directly as a SymPy expression (using parse_expr()

I haven't tried it but I imagine it would. The biggest challenge would
be the serialization method. SymPy can have issues with things like
pickle sometimes.

Ah that's interesting. I would consider that to be a bug. I would expect
apart() to just be assemble_partfrac_list(apart_list()), but apparently
there is a lot of duplicated logic. Can you open a bug report about this

representable by the set of things that the old assumptions can
represent. The only way to represent more advanced relations like x >
y is to use a different syntax from what the old assumptions use,
which is the idea behind the new assumptions.
Also, the old assumptions aren't goin
Yes, that is what I mean by only getting the real roots. I don't think it's
possible now, though it shouldn't be hard to do it manually with
apart_list().

To get the version you mentioned, you should use
>>> (Integer(149)/35).evalf(16)
4.257142857142857
>>> Rational(str((Integer(149)/35).evalf(16)))
4257142857142857/1000

work like this, where if you
change a coefficient it changes the behavior of it. That's because it's
easy for a polynomial to have a rational root with one coefficient but not
with another close coefficient, like in this case.

I wouldn't recommend using threads with SymPy. Even if it works (which
I expect it won't because we do have global things like the cache),
the Python GIL would prevent it from truly working concurrently.
Instead, use different processes.

There's also https://github.com/sympy/scipy-2016-tutorial (there may
be a newer version somewhere).

I don't recall anyone objecting to it. If no one does, I would go
ahead and start working on it. I think no work was done here because
no one had the time to organize the sympy-notebooks repo.

one way. Getting funding to
improve things is another.
- We have a documentation style guide, which was developed as part of
last year's GSoD. However, only a small subset of SymPy actually
conforms to the guide
