HowTo Get LaTeX code of original formula (without expand/simplify)?

[Michał Pawłowski]

Hi.

I'd like to get LaTeX code of formula, but without simplification or expanding. I.E:

formula_1 = '2+x+x**2'

print(latex(expand(formula_1))) <- this works but it sorts the formula

print(latex(???)) -> 2+x+x^{2} #HOW TO GET THIS?

Thanks

Mike.

SymPy generally doesn't keep track of the order that an input expression was created in. The best you can get is something like this

latex(sympify('2+x+x**2', evaluate=False), order='none')

The limitation here is that evaluate=False is not generally going to survive if you call some other function or combine with some other expression.
