isympy - interactive shell for SymPy


isympy [-c | --console] isympy [ {-h | --help} | {-v | --version} ]


isympy is a Python shell for SymPy. It is just a normal python shell (ipython shell if you have the ipython package installed) that executes the following commands so that you don't have to:
 >>> from __future__ import division
 >>> from sympy import *
 >>> x, y, z = symbols("xyz")
 >>> k, m, n = symbols("kmn", integer=True)

So starting isympy is equivalent to starting python (or ipython) and executing the above commands by hand. It is intended for easy and quick experimentation with SymPy. For more complicated programs, it is recommended to write a script and import things explicitly (using the "from sympy import sin, log, Symbol, ..." idiom).


-c shell, --console=shell
Use the specified shell (python or ipython) as console backend instead of the default one (ipython if present or python otherwise).

Example: isympy -c python


Saves the history of commands when using the python shell as backend.

La Nature déploie la même splendeur sans limite dans l'Atome ou
dans la Nébuleuse, et tout moyen nouveau de connaissance la
montre plus vaste et diverse, plus féconde, plus imprévue, plus
belle, plus riche d'insondable Immensité.
