title: Using sympy's latex() function without calculating the input
body: <p>I want to get latex output from a sympy expression without calculating the expression. For instance if I do latex((2+3)/7) the output would be 5/7 (with latex), but what I am after is for it to just output (2+3)/7 with latex.  Like this: \frac{2+3}{7} </p>
