Hi, I am new to sympy and I have a basic question.
I would like to use sympy to sovle simple sets of equations in a text
editor.
like given the following as plain text:
a = 10
b = 20
a * 12 + 50*c == 456 + b
and an instruction to solve for c, then ptorduce:
c = 7.12
I know sympy comes with a
Hullo Sympy Group,
In my code, I'd like to be able to specify symbols with a binary type,
something akin to:
* b = symbols('b', binary=True)*
This would let *b* assume only values from the set *{0, 1}*. I see the *
Boolean* class from which the *Symbol* class derives, but I believe that's
Hello,
try the following.
Best regards.

a = 10
b = 20
print solve(a * 12 + 50*c - (456 + b), c)

It's not clear what exactly you want to do. Here are some

In [12]: sympify(a*12 + 50*c)
Out[12]: 12⋅a + 50⋅c
Note that I did not have a or c
So you want to assume that b is a number modulo 2. To do this, you
can use the new Mod() object that was recently added. Note that this
was added after the latest release, so you'll have to use the git
version if you want to use it.
You define b = Symbol('b', integer=True), and use Mod(b, 2)
So should make htmli18n be run before uploading the docs to docs.sympy.org?

For this project, my end goal is to interface a series of Sympy equations
that I've built to an optimization solver. In the context of optimization,
binary variables usually represent a decision, and in the context of
solving, they represent a branch point. Branch points make it expensive

Hullo Sympy Group,
I'm wrapping some Sympy variables into a group via a class object. The
object is attached to another object, and from here, I'm able to collect
the name of the group (via *__setattr__*). Thus, I can have constructs
like this:
-
*M.X = Var()# Var is the wrapper
The colors are only for visual purposes. They correspond to the the
letters and have no additional meaning.
Other letters that are used are:
T - timeout (e.g., when --timeout is used)
K - KeyboardInterrupt (when running the slow tests with --slow, you
can interrupt one of them without killing

For many of the classes in secondquant dealing with state they will
not print. Most of them are because of not having a variable lbracket
