LaTeX expresentation as input in SymPy

[redstone-cold]

I have found this function

latex(expr, **settings):

can Convert the given expression to LaTeX representation,but is there any function can take LaTeX expresentation so that it can be used in SymPy ?

i.e. is there any function can take 

\dfrac{2x+2}{2x^3-3x^2+3x+3}

as input in SymPy ?

We don't have it but we do want it. See https://github.com/sympy/sympy/issues/5418. Note that parse_expr can already handle the basic stuff (like implicit multiplication).

Demo ware by necessity.   How can you distinguish  (d*y)/ (d*x)    from diff(y,x)  written as \frac{dy}{dx} ?

And it gets worse as notation gets more subtle.

sure you can do a+b*c.

Why not allow speech input?

Speech input would be great, but hard work to achieve it.
