Please help me with the code of this. It is in Python OOP form like there is __init__ or so what. Below are the infix that must be converted into postfix expressions. Thank you very much.

C:\Documents and Settings Admin\Desktop\In2 post.exe WWW-WINFIX TO POSTFIX HHHH Enter the infix expression > A*B/2 C-D Postfix Expression is :: AB*2/CD- CONVERTING INFIX TO POSTFIX EXPRESSION. The method of converting infix expression A+B C to postfix form is: A+B*C Infix Form A+( BC) Parenthesized expression A +(BC*) Convert the multiplication A (BC*)+ Convert the addition ABC* + Postfix form The rules to be remembered during infix to postfix conversion are: 1. Parenthesize the expression starting from left to light. 2. During parenthesizing the expression, the operands associated with operator having higher precedence are first parenthesized. For example in the above expression B *C is parenthesized first before A+B. 3. The sub-expression (part of expression), which has been converted into postfix, is to be treated as single operand. 4. Once the expression is converted to postfix form, remove the parenthesis. Example: Give postfix form for A+[(B+C)+(D+E) *F]/G Solution: Evaluation order is A+{[(BC +) + DE +) 'F]/G} A+{[(BC+) + (DE +F *]/G} A+{[(BC+ (DE+F*+]/G}. A+ [BC +DE+F*+G/] ABC +DE+F*+G/+ Postfix Form Using Infix expression, convert the following into a postfix expression. INFIX (A + B) * C/D+E^ A/B (A+B) + C/DEA A/B (A + B)/C/D.E^ A/B (A + B) - C/D-EAA/B (A+B) +C/DE A/B POSTFIX AB+CD/EAAB/+ AB + CD/EA^* B/+ AB+C/D/EA^*B/ AB + CD/- EAB/- AB + CD/EA^* B/+
