I have a lot of latex expression, such as:
a+b+c=0
abc>0
\frac{1}{a}+\frac{1}{b}+\frac{1}{c}
\left({a+b+c}\right)^2=a^2+b^2+c^2+2ab+2bc+2ac=0

I want a function, let's say latex2sympy(latex), to convert latex to sympy expression?

how can i do that?

Hello.

Because LaTeX is not mathmetically semantic, you can't have a perfect converter from LaTeX to SymPy.

see, for example,

for a discussion.  It is really a consideration of "optical character recognition"
of math equations, where the characters are mostly perfectly represented,
and the spacing is perfectly represented.  But what is the meaning of, say,
a superscript?  

To find info, consider that google is your friend.
