Can you elaborate the idea of a complex number module which can add and
subtract?
For example, do you want to represent things coerced into a 2-tuple
representation, than representing everything with a multiplication with
imaginary unit?

sympify() can only parse things that are valid Python, meaning it can
only work with symbol names that are valid Python variable names.
E_1m1 is a valid Python variable name but E_{1\,-1} is not. If you
need to get a parsable string form for an expression you can use
srepr(), which would create a
Hello Aaron,
thanks for the reply. First, subst() is a typo, and should be subs(), but
I'm not using it here anyway.
The test program contains this definition:
E1m1 = symbols('E_{1\,-1}')
so you can see that I am using the _ in it. The problem is the conversion
to latex, which recognizes E11,
SymPy also comes with Anaconda. Anaconda basically installs a
completely separate Python installation, but as long as the same
installation includes SymPy and matplotlib they will be able to work
with each other.
The issue is that things like tkinter or qt that are needed for
matplotlib plotting
What is subst()?
Is the problem here that SymPy does not convert E1m1 into a LaTeX
string with subscripts? You can use _ in the symbol name to indicate
that part of it should be subscripted. For example
>>> latex(Symbol("E_1m1"))
'E_{1m1}'

Thanks Aaron, but
I just discovered something. Instead of symbols(str), I should be using
sympify(str), but that doesn't seem to change anything.

I think it would be better if sympy's plotting module didn't try to
wrap up other libraries as "backends" but instead

Tx for replying.
I'm working on which issue to tackle. Currently I'm going through the codebase
of SymPy, which is almost over. After that I'll post which issues i have in my
mind to solve.

IMO, anyone can suggest more concretely if you can come up with the list of
issues you want to address with a brief explanation of your approach to fix
them.
You can also refer to previous discussions in the group.

I need to create a large number of equations in different variations, and
they involve symbols such as
E1m1 = symbols('E_{1\,-1}')
Since subst() does not work for symbols, I create the string 'E1m1' as
('E'+str(1)+str(-1)).replace('-', 'm')
and then use symbols(str). This is working fine for
17 matches
