And thereafter, a parsing algorithm based on operator precedence is proposed in the paper, with the algorithm formalized and the complexity analyzed. The proposed ideas have been proved valid and realistic through the application to parsing Chinese sentences. Further researches are needed to put it ...
Operator-Precedence parsing cannot handle the unary minus when we have also the binary minus in our grammar. The best approach to solve this problem, let the lexical yzer handle this problem. The lexical yzer will return two different operators for the unary minus and the binary minus. The le...
The precedence of the walrus operator can cause some confusion. It binds less tightly than all other operators except the comma, so you might need parentheses to delimit the expression that you’re assigning. As an example, note what happens when you don’t use parentheses: Python >>> numb...
