numpsy 0.0.12
NumpSy - Integrated NumPy, SymPy, SciPy and Pandas with unit management for scientific programming with IPython.
Requires Python: >=3.6

# NumpSy

Straight up mix between NumPy, SymPy and Pandas into a value single-declaration extendable framework to simulatenously perform symbolic and numerical operations.

Objectives:
1. Ever think you wanted to simultaneously perform numerical and symbolic mathematics for an engineering or optimization derivation? Now you can pretty much intuitively derivate simultaneously whilst performing unit management automatically.
2. Integrate mathematical analytical derivation Python toolchains into a single handy one that retains and expands each of the constituent packages methods. Retain intuitive compatibility.
3. Have fun!

### Is it any good?
I think it's an elegant mathematical representation to simultanously perform symbolic, numerical, and data science operations into a single system. It targets a minimal overhead to raw numpy, sympy or scipy operations.

## Quick Start

Download the [Anaconda distribution first](https://www.anaconda.com/).

Pip install:
```bash
$ pip install numpsy
```

Local install for most recent version:
```bash
$ git clone https://github.com/daquintero/numpsy.git
$ cd numpsy
$ python3 setup.py install
```

## Quick Example
See the [10 minutes to NumpSy jupyter notebook](https://github.com/daquintero/numpsy/blob/master/docs/ten_minutes_to_numpsy/10_minutes_to_numpsy.ipynb) for much more.

### Installation

*Import NumpSy*


```python
import numpsy as nsy
```

## Units

#### Declare a Unit


```python
meter = nsy.Unit(name="meter", symbol="m")
meter
```




|                     | Unit                            |

#### Constants cannot be mutated


```python
e_d.n = 10
```

    Constant cannot be mutated. You cannot set any attribute value. Instantiate a new variable.


## Variable


```python
capacitor_plate_separation = nsy.Variable(
    name="capacitor_plate_separation",
    symbol= "d",
    numerical=None,
    unit=nsy.u.meter
)
capacitor_plate_separation
```

### Future plans
* Extend unit management and verification.
* Create a full constants list, probably even in Excel or as an importable CSV file into Pandas.

Open to contributions.
