CSSRuleListc@sLeZdZdZddZddZeZZZZ ddZ e dd Z d d Z d S) raThe CSSRuleList object represents an (ordered) list of statements. The items in the CSSRuleList are accessible via an integral index, starting from 0. Subclasses a standard Python list so theoretically all standard list methods are available. Setting methods like ``__init__``, ``append``, ``extend`` or ``__setslice__`` are added later on instances of this class if so desired. E.g. CSSStyleSheet adds ``append`` which is not available in a simple instance of this class! cGsdS)z2Nothing is set as this must also be defined later.NselfignoredrrL/var/www/html/myenv/lib/python3.10/site-packages/cssutils/css/cssrulelist.py__init__szCSSRuleList.__init__cGstd)z.Implemented in class using a CSSRuleList only.z=Must be implemented by class using an instance of this class.)NotImplementedErrorrrrr__notimplementedszCSSRuleList.__notimplementedcCs z||WStyYdSw)a(DOM) Retrieve a CSS rule by ordinal `index`.
