Stack-Calc

A calculator based on Python's list-like stack.

Usage

1. Make sure python==3.8 is installed on your computer.
2. Run /path/to/python app.py in root folder of project.
3. Enter arguments as needed.

Installation

No need to install! Just use it!

If you have to install it, just run sh install.sh (or make install). It will copy all .py files to ~/.local/lib/python3.8/site-packages/ctack-calc. Use sh uninstall.sh (or make uninstall) to uninstall.

Description of files

• app.py: The main application.
• argparsing.py: The argument parsing module meant to be imported by app.py to parse command-line arguments.
• by_operands.py: The module that seperates SOperator into NoOperand, SingleOperand, and DoubleOperand.
• convert.py: The module that converts between postfix and infix expressions.
• exceptions.py: The module that defines InputError for the calculator.
• new_operator.py: The module that defines function new_operator for creating an operator.
• soperator.py: The module that defines class SOperator that represents a stack operator. (Pretty cool name, huh?)
• stack.py: The module that defines class Stack that imitates a stack that is powered by a list.
• utils.py: The module that defines some utilities used in the application.

Post-fix and in-fix expressions

A post-fix expression is an expression in which the operator follows the operands. This is in contrast to an in-fix expression, where the operator is between the operands. This calculator supports both types - just pass -i/--infix for infix notation, and -p/--postfix for postfix notation. The default is postfix.

Contribution

I welcome contributors, if there are any 😄 If you wish to contribute, simply clone this repository, add any code you wish, and then open a pull request. (I really need more operators...)
