This project is a multi-purpose tool developed in Python that serves as both a command-line calculator and a plotter for single-variable mathematical functions (x). The goal is to provide a simple and user-friendly interface to perform quick calculations and visualize the behavior of different functions on a 2D graph.
This project was developed as part of my learning journey in Data Science and as a Mathematician, applying concepts of programming logic, string manipulation with Regex, and the use of fundamental libraries from the Python ecosystem.
- Dual Mode: Choose between using the tool as a direct expression calculator or as a function plotter.
- Function Plotter: Enter any function of
xand instantly visualize its graph. - User-Friendly Syntax: The parser accepts common shortcuts:
x^2for exponents (is converted tox**2).5xfor implicit multiplication (is converted to5*x).
- Safe Evaluation: Uses the
numexprlibrary to evaluate expressions, avoiding the security risks of theeval()function.
- Python
- NumPy: For array generation and numerical computations.
- Matplotlib: For data visualization and plotting.
- NumExpr: For the safe evaluation of mathematical expressions.
- Regex (
remodule): For preprocessing and correcting user-input formulas.
To run this project on your local machine, follow the steps below:
-
Clone the repository:
git clone [https://github.com/Silea-Dev/mini-geogebra.git](https://github.com/Silea-Dev/mini-geogebra.git) cd mini-geogebra -
Create a virtual environment (Recommended):
python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate
-
Install the dependencies:
pip install -r requirements.txt
-
Run the program:
python main.py
- v2.0: Implement the plotting of multiple functions on the same graph.
- Add more graph customization options (colors, line styles).
- Allow the user to define the
xrange to be plotted.
