simple arithmetic calculator

Python implements a simple arithmetic calculator, python I. Algorithms 1. The main idea of the algorithm is to convert an Infix expression into a Postfix expression, and then use the stack's simple data structure, returns the result of an expression.

First, the algorithm 1, the main idea of the algorithm is to convert an infix expression (Infix expression) into a convenient suffix expression (Postfix expression), and then with the help of the stack of this simple data structure, to calculate
