A simple math library with basic operations

MathLib: A Simple Python Library for Basic Mathematical Operations

MathLib is a simple Python library for basic mathematical operations, including arithmetic and algebraic functions. It's designed to be easy to use and extendable for more advanced mathematical operations.

Features

• Arithmetic Operations: Addition, subtraction, multiplication, and division.
• Algebraic Operations: Solving simple linear equations.

Important steps

Step 1: Set Up the Project Structure

First, set up your directory structure:

MathLib/
├── mathlib/
│   ├── __init__.py
│   ├── arithmetic.py
│   ├── algebra.py
│   ├── complex_numbers.py
│   ├── logarithmic.py
│   ├── matrix_operations.py
│   ├── power_roots.py
│   ├── random_utils.py
│   ├── statistics.py
│   ├── trigonometry.py
│   └── utility.py
├── tests/
│   ├── test_arithmetic.py
│   ├── test_algebra.py
│   ├── test_complex_numbers.py
│   ├── test_logarithmic.py
│   ├── test_matrix_operations.py
│   ├── test_power_roots.py
│   ├── test_random_utils.py
│   ├── test_statistics.py
│   ├── test_trigonometry.py
│   └── test_utility.py
├── setup.py
├── README.md
└── LICENSE

Step 2: Write the Package Code

mathlib/__init__.py

This file makes the mathlib directory a package.

# mathlib/__init__.py

from .arithmetic import add, subtract, multiply, divide, power
from .algebra import solve_linear, solve_quadratic
from .trigonometry import sin, cos, tan, arcsin, arccos, arctan
from .statistics import mean, median, variance, standard_deviation
from .matrix_operations import matrix_addition, matrix_multiplication, matrix_determinant, matrix_inverse
from .complex_numbers import complex_addition, complex_subtraction, complex_multiplication, complex_division, complex_magnitude, complex_phase
from .random_utils import random_integer, random_float
from .utility import factorial, gcd, lcm

__all__ = [
    'add', 'subtract', 'multiply', 'divide', 'power',
    'solve_linear', 'solve_quadratic',
    'sin', 'cos', 'tan', 'arcsin', 'arccos', 'arctan',
    'mean', 'median', 'variance', 'standard_deviation',
    'matrix_addition', 'matrix_multiplication', 'matrix_determinant', 'matrix_inverse',
    'complex_addition', 'complex_subtraction', 'complex_multiplication', 'complex_division', 'complex_magnitude', 'complex_phase',
    'random_integer', 'random_float',
    'factorial', 'gcd', 'lcm'
]

Next Create the python files for various kind of mathematical functions.

Step 3: Write Tests

To ensure your package functions as expected, it's essential to write some basic tests. Pytest is a powerful tool for this purpose and is widely recommended for Python projects. It helps you write simple and scalable test cases to validate your code.

Step 4: Set Up the Package Metadata

setup.py

# setup.py

from setuptools import setup, find_packages

setup(
    name='mathlib',
    version='0.1',
    packages=find_packages(),
    description='A simple math library with basic operations',
    long_description=open('README.md').read(),
    long_description_content_type='text/markdown',
    author='Arun Kumar Pandey',
    author_email='[e-mail]',
    url='https://github.com/arunp77/mathlib-package.git',
    license='MIT',
    install_requires=[],
    classifiers=[
        'Programming Language :: Python :: 3',
        'License :: OSI Approved :: MIT License',
        'Operating System :: OS Independent',
    ],
)

This setup.py file is used to install the package using pip. It includes metadata such as

Testing

To run the tests for this project, use pytest:

pytest tests/

This will run the test suite located in the tests directory, ensuring that all functions work as expected.

To check the individial operations, go to the test folder and run each file with pytest. FOr example, to check the operations insdie the functions defined in algebra.py, run:

pytest algebra.py

Installation

• Step-1: Install the Package Locally

  You can install MathLib directly from the source code:

  git clone https://github.com/arunp77/Data-engineering-tools.git
  

  Navigate to the root directory of your project (where setup.py is located)

  cd /Data-engineering-tools/mathlib
  

  and then run:

  pip install -e . -v
  

  The -e flag stands for "editable," which means any changes you make to the code will immediately be reflected without needing to reinstall the package. Here -v will give you more detailed output about what is happening during the installation process.

  

  We can alsi install it using:

  pip install mathlib
  

  

• Step 2: Verify Installation

  After running the installation, you can verify that the package was installed by running:

  pip show mathlib
  

  This should display information about the mathlib package, such as the version and location.

  Verify Import in Python Shell: Try importing mathlib directly in the Python shell to ensure it is correctly recognized:

  >>> import mathlib
  
  >>> mathlib
  

  We can also install mathlib, directly using setup.py file, using:

  python setup.py install --verbose
  

  This will give you more detailed output about what is happening during the installation process.

  If you're using pip install, you can add the -v option for verbose output:

• Step 3: Run the Tests Once the package is installed, you should run the tests to ensure everything is working as expected.

  Navigate to the root directory of your project and run:

    pytest tests/
  

  This will execute the tests defined in tests/test_arithmetic.py and tests/test_algebra.py. If all the tests pass, it indicates that your package is functioning correctly.

• Step 4: Create Docekrimage

  docker build -t arunp77/mathlib:latest .
  

  and then push it to DOcker.

  docker push arunp77/mathlib:latest
  

  Here, you must remember that, you must have created a Docker Access token from the DOcker hub and then saved it to your Github secrets. FOr more details on this, you can follow step by step guide provided at my documentation page created for another project
