Recursive-Descent-Parser-using-python

This is program of recursive descent parser using Python programming language.

Recursive Descent Parser:

It is a kind of Top-Down Parser. A top-down parser builds the parse tree from the top to down, starting with the start non-terminal. A Predictive Parser is a special case of Recursive Descent Parser, where no Back Tracking is required. By carefully writing a grammar means eliminating left recursion and left factoring from it, the resulting grammar will be a grammar that can be parsed by a recursive descent parser.

Here 'i' is Epsilon or any terminals symbol.

For Recursive Descent Parser, we are going to write one program for every variable.

Any suggestion regarding this program is helpful for me
