When the parser returns PARSE_INCOMPLETE then you know that the expression is not complete and thus more input is needed. If you are directly interfacing R from Python then you can easily do exactly the same thing. However, if you want a solution in pure Python, it may be more difficult as it would be equal to re-writing the R parser in Python... (or some 'light' version of it..).
