MathematicaToPython

Mathematica package to convert MATHEMATICA expressions to Python Numpy

Quick usage

The quickest way to use the package is to directly load it from the master branch of this repository by running the following code in a Mathematica notebook:

Import["https://raw.githubusercontent.com/zwicker-group/MathematicaToPython/master/ToPython.wl"]

Installation

To install the package permanently, do the following

1. Download it from this repository
2. Click on Mathematica' File menu-> Install->From file...
3. Select the file on your disk

You should be ready to go.

Usage

The package mainly provides the ToPython function, which takes a Mathematica expression and tries to convert it to a python expression. It can handle a lot of expressions already, but it is obviously limited.

Beside the actual expression the ToPython function also supports two options:

• NumpyPrefix, which determines the name under which numpy is imported. The default is to prefix all numpy call with np., but you can also set NumpyPrefix to "numpy" to enforce numpy. as a prefix. If you supply an empty string, no prefix is added, which might be useful if you use the wildcard import from numpy import *
• Copy, which when enabled copies the formatted expression to the clipboard

Taken together, a simple example call is

ToPython[Sin[x], NumpyPrefix->"numpy", Copy->True]

which should copy numpy.sin(x) to your clipboard.
