Parameters ========== pretty_print: boolean If True, use pretty_print to stringify or the provided pretty printer; if False, use sstrrepr to stringify or the provided string printer. 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: string, boolean, or None If True, use default latex rendering in GUI interfaces (png and mathjax); if False, do not use latex rendering; if 'png', enable latex rendering with an external latex compiler, falling back to matplotlib if external compilation fails; if 'matplotlib', enable latex rendering with matplotlib; if 'mathjax', enable latex text generation, for example MathJax rendering in IPython notebook or text rendering in LaTeX documents wrap_line: boolean If True, lines will wrap at the end; if False, they will not wrap but continue as one line. This is only relevant if `pretty_print` is True. num_columns: int or None If int, number of columns before wrapping is set to num_columns; if None, number of columns before wrapping is set to terminal width. This is only relevant if `pretty_print` is True. no_global: boolean If True, the settings become system wide; if False, use just for this console/session. ip: An interactive console This can either be an instance of IPython, or a class that derives from code.InteractiveConsole. euler: boolean, optional, default=False Loads the euler package in the LaTeX preamble for handwritten style fonts (http://www.ctan.org/pkg/euler). forecolor: string, optional, default='Black' DVI setting for foreground color. backcolor: string, optional, default='Transparent' DVI setting for background color. fontsize: string, optional, default='10pt' A font size to pass to the LaTeX documentclass function in the preamble. latex_mode: string, optional, default='plain' The mode used in the LaTeX printer. Can be one of: {'inline'|'plain'|'equation'|'equation*'}. print_builtin: boolean, optional, default=True If true then floats and integers will be printed. If false the printer will only print SymPy types. 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().
