(Line and column numbers are 1-based by default - if debugging a parse action, pass base_1=False, to correspond to the loc value passed to the parse action.) :param s: string to be printed with line and column numbers :param start_line: starting line number in s to print (default=1) :param end_line: ending line number in s to print (default=len(s)) :param expand_tabs: expand tabs to spaces, to match the pyparsing default :param eol_mark: string to mark the end of lines, helps visualize trailing spaces :param mark_spaces: special character to display in place of spaces :param mark_control: convert non-printing control characters to a placeholding character; valid values: - ``"unicode"`` - replaces control chars with Unicode symbols, such as "␍" and "␊" - any single character string - replace control characters with given string - ``None`` (default) - string is displayed as-is :param indent: string to indent with line and column numbers; if an int is passed, converted to ``" " * indent`` :param base_1: whether to label string using base 1; if False, string will be labeled based at 0 :returns: input string with leading line numbers and column number headers .. versionchanged:: 3.2.0 New ``indent`` and ``base_1`` arguments.
