How to convert Math Formula to Python code?

问题:

Are there any easy ways to convert mathematical formulas to Python code? Perhaps translators, web reference, specific book chapters, anything ~

For regular expressions there are programs such as Kodos and sites such as pythonregex.com, so I was hoping there would be something similar for formula notation and Python.

回答1:

No, this isn't possible in general. There are mathematical functions that aren't computable (for example, see wikipedia/Halting_problem). There are other mathematical functions where it's just not obvious how to code them up (consider a difficult integral or differential equations). There are many books written on finding numerical solutions to these sorts of problems (you can find some links here: wikipedia/Numerical_analysis).

For simple cases, you can transcribe mathematical formulae directly, but any automated means of translation would require a formal language for writing mathematical formulae in what would be a programming language in itself. This would beg the question, since you would be trading writing mathematical formulae in one language with writing them in another.

You could try to make your own with sympy and pyparsing.
