Description:
 def explain(exc, depth=16):
 """ Method to take an exception and translate the Python internal traceback into a list of the pyparsing expressions that caused the exception to be raised. Parameters: - exc - exception raised during parsing (need not be a ParseException, in support of Python exceptions that might be raised in a parse action) - depth (default=16) - number of levels back in the stack trace to list expression and function names; if None, the full stack trace names will be listed; if 0, only the failing input line, marker, and exception string will be shown Returns a multi-line string listing the ParserElements and/or function names in the exception's stack trace. Note: the diagnostic output will include string representations of the expressions that failed to parse. These representations will be more helpful if you use `setName` to give identifiable names to your expressions. Otherwise they will use the default string forms, which may be cryptic to read. explain() is only supported under Python 3. """
