def escape_string(self, value):
return str(value)<EOL>
Escape a string.

        Escape the given string so that special characters (such as quotes and
        whitespace) are treated properly. If `value` is a string, assume that
        this is an expandable string in this interpreter.

        Note:
            This default implementation returns the string with no escaping
            applied.

        Args:
            value (str or `EscapedString`): String to escape.
