determining numerator and denominator in a relatively complex mathematical expression using python

Question

I'm trying to convert calculator input to LaTeX. if a user inputs this:

(3x^(x+(5/x)+(x/33))+y)/(32 + 5)

I have to convert it to this:

frac{3x^(x+frac{5}{x}+frac{x}{33})+y}{32 + 5x}

however I am having issues with determining when a numerator begins and ends. Any suggestions?

Answer 1

Have a look at compiler

compiler.parse('(3*x**(x+(5/x)+(x/33))+y)/(32 + 5)')

returns

Module(None, Stmt([Discard(Div((Add((Mul((Const(3), Power((Name('x'), Add((Add((Name('x'), Div((Const(5), Name('x'))))), Div((Name('x'), Const(33))))))))), Name('y'))), Add((Const(32), Const(5))))))]))

which could be more easily converted to LaTeX code. You will have to write methods, that handle each code (Div, Add, Const, Name, Power,...) and its parameters recursively and return appropriate LateX code.
