The IPython session is initiated with the --pylab option, without the numpy imports, so that matplotlib plotting can be interactive. Parameters ========== pretty_print: boolean If True, use pretty_print to stringify; if False, use sstrrepr to stringify. order: string or None There are a few different settings for this parameter: lex (default), which is lexographic order; grlex, which is graded lexographic order; grevlex, which is reversed graded lexographic order; old, which is used for compatibility reasons and for long expressions; None, which sets it to lex. use_unicode: boolean or None If True, use unicode characters; if False, do not use unicode characters. use_latex: boolean or None If True, use latex rendering if IPython GUI's; if False, do not use latex rendering. quiet: boolean If True, init_session will not print messages regarding its status; if False, init_session will print messages regarding its status. auto_symbols: boolean If True, IPython will automatically create symbols for you. If False, it will not. The default is False. auto_int_to_Integer: boolean If True, IPython will automatically wrap int literals with Integer, so that things like 1/2 give Rational(1, 2). If False, it will not. The default is False. ipython: boolean or None If True, printing will initialize for an IPython console; if False, printing will initialize for a normal console; The default is None, which automatically determines whether we are in an ipython instance or not. str_printer: function, optional, default=None A custom string printer function. This should mimic sympy.printing.sstrrepr(). pretty_printer: function, optional, default=None A custom pretty printer. This should mimic sympy.printing.pretty(). latex_printer: function, optional, default=None A custom LaTeX printer. This should mimic sympy.printing.latex() This should mimic sympy.printing.latex(). argv: list of arguments for IPython See sympy.bin.isympy for options that can be used to initialize IPython. See Also ======== sympy.interactive.printing.init_printing: for examples and the rest of the parameters.
