# PolStringConvertor
PolStringConvertor is a Python package that provides utilities to convert infix expressions into postfix and prefix forms, and to evaluate postfix expressions. It also includes validation of infix expressions.
## Features
- Validate infix expressions for proper operator placement and balanced parentheses.
- Convert infix expressions to postfix notation.
- Convert infix expressions to prefix notation.
- Evaluate postfix expressions.
## Installation
To install the package, use pip:
```bash
pip install PolStringConvertor
```
This package requires the `StrTokenizer` package version 1.1.0 to function properly. It will be installed automatically when you install `PolStringConvertor`.
## Usage
Here’s how to use the main features of the package:
### 1. Validate an Infix Expression
```python
from PolStringConvertor import isExpressionValid
expression = "(a+b)*c"
print(isExpressionValid(expression)) # Returns True or False
```
### 2. Convert Infix to Postfix
```python
from PolStringConvertor import infixToPostfix
expression = "(a+b)*c"
postfix = infixToPostfix(expression)
print(postfix) # Output: ['a', 'b', '+', 'c', '*']
```
### 3. Convert Infix to Prefix
```python
from PolStringConvertor import infixToPrefix
expression = "(a+b)*c"
prefix = infixToPrefix(expression)
print(prefix) # Output: ['*', '+', 'a', 'b', 'c']
```
### 4. Evaluate a Postfix Expression
```python
from PolStringConvertor import evaluatePostfixExpression
postfix = ['3', '4', '+', '2', '*', '7', '/']
result = evaluatePostfixExpression(postfix)
print(result) # Output: 2.0
```
### 5. Import All Functions at once
```python
from PolStringConvertor import *
expression = "(a+b)*c"
print(isExpressionValid(expression)) # Returns True or False
postfix = infixToPostfix(expression)
print(postfix) # Output: ['a', 'b', '+', 'c', '*']
prefix = infixToPrefix(expression)
print(prefix) # Output: ['*', '+', 'a', 'b', 'c']
postfix = ['3', '4', '+', '2', '*', '7', '/']
result = evaluatePostfixExpression(postfix)
print(result) # Output: 2.0
```
