Generally, the data is in key:value format with values having data types as string, numbers, list or dictionary. The class provides attribute ``data`` as list with lines parsed line by line based on keys for each bridge. Sample command output:: name : br-int other_config : {disable-in-band="true", mac-table-size="2048"} name : br-tun other_config : {} Examples: >>> bridge_lists[0]["name"] 'br-int' >>> bridge_lists[0]["other_config"]["mac-table-size"] '2048' >>> bridge_lists[0]["other_config"]["disable-in-band"] 'true' >>> bridge_lists[1].get("name") 'br-tun' >>> len(bridge_lists[1]["other_config"]) == 0 True Attributes: data (list): A list containing dictionary elements where each element contains the details of a bridge.
