-Python 使用以下配置项创建一个 Consumer 实例。
+Python 语言下引入 `taos` 库的 `TaosConsumer` 类，创建一个 Consumer 示例：

+```python
+from taos.tmq import TaosConsumer
+
+# Syntax: `consumer = TaosConsumer(*topics, **args)`
+#
+# Example:
+consumer = TaosConsumer('topic1', 'topic2', td_connect_ip = "127.0.0.1", group_id = "local")
