    Initializes pretty-printer depending on the environment.

    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.
    wrap_line: boolean
        If True, lines will wrap at the end;
        if False, they will not wrap but continue as one line.
    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.
    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.
