-### Preparation
+### Pre-installation preparation
 
 1. Install Python. The recent taospy package requires Python 3.6.2+. The earlier versions of taospy require Python 3.7+.  The taos-ws-py package requires Python 3.7+. If Python is not available on your system, refer to the [Python BeginnersGuide](https://wiki.python.org/moin/BeginnersGuide/Download) to install it.
 2. Install [pip](https://pypi.org/project/pip/). In most cases, the Python installer comes with the pip utility. If not, please refer to [pip documentation](https://pip.pypa.io/en/stable/installation/) to install it.

-The `consumer` in the connector contains the subscription api. 
-
-##### Create Consumer
-
-The syntax for creating a consumer is `consumer = Consumer(configs)`. For more subscription api parameters, please refer to [Data Subscription](../../../develop/tmq/).
+##### Create Stmt
 
-```python
-from taos.tmq import Consumer
+Call the `statement` method in `Connection` to create the `stmt` for parameter binding.
 
-consumer = Consumer({"group.id": "local", "td.connect.ip": "127.0.0.1"})

-##### Subscribe topics
-
-The `subscribe` function is used to subscribe to a list of topics.
-
-```python
-consumer.subscribe(['topic1', 'topic2'])
+conn = taos.connect()
+stmt = conn.statement("insert into log values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)")
 ```
 
-##### Consume
-
-The `poll` function is used to consume data in tmq. The parameter of the `poll` function is a value of type float representing the timeout in seconds. It returns a `Message` before timing out, or `None` on timing out. You have to handle error messages in response data.
+##### parameter binding

-    val = res.value()
+Call the `new_multi_binds` function to create the parameter list for parameter bindings.
 
-    for block in val:
-        print(block.fetchall())
 ```
-
-##### assignment
-
-The `assignment` function is used to get the assignment of the topic. 
-
-```python

-`Consumer` 提供了 Python 连接器订阅 TMQ 数据的 API。
-
-##### 创建 Consumer
-
-创建 Consumer 语法为 `consumer = Consumer(configs)`，参数定义请参考 [数据订阅文档](../../develop/tmq/#%E5%88%9B%E5%BB%BA%E6%B6%88%E8%B4%B9%E8%80%85-consumer)。
+##### 创建 stmt
 
-```python
-from taos.tmq import Consumer
+Python 连接器的 `Connection` 提供了 `statement` 方法用于创建参数绑定对象 stmt，该方法接收 sql 字符串作为参数，sql 字符串目前仅支持用 `?` 来代表绑定的参数。
 
-consumer = Consumer({"group.id": "local", "td.connect.ip": "127.0.0.1"})
 ```
+import taos
 
-##### 订阅 topics
-
-Consumer API 的 `subscribe` 方法用于订阅 topics，consumer 支持同时订阅多个 topic。
-
-```python
-consumer.subscribe(['topic1', 'topic2'])
+conn = taos.connect()
+stmt = conn.statement("insert into log values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)")
 ```
 
-##### 消费数据
-
-Consumer API 的 `poll` 方法用于消费数据，`poll` 方法接收一个 float 类型的超时时间，超时时间单位为秒（s），`poll` 方法在超时之前返回一条 Message 类型的数据或超时返回 `None`。消费者必须通过 Message 的 `error()` 方法校验返回数据的 error 信息。
+##### 参数绑定
 
-```python
-while True:
-    res = consumer.poll(1)
-    if not res:
-        continue
-    err = res.error()
-    if err is not None:
-        raise err
-    val = res.value()
+调用 `new_multi_binds` 函数创建 params 列表，用于参数绑定。
 
-    for block in val:
-        print(block.fetchall())
+```
+params = new_multi_binds(16)
+params[0].timestamp((1626861392589, 1626861392590, 1626861392591))
+params[1].bool((True, None, False))
+params[2].tinyint([-128, -128, None])  # -128 is tinyint null
+params[3].tinyint([0, 127, None])
+params[4].smallint([3, None, 2])
+params[5].int([3, 4, None])
+params[6].bigint([3, 4, None])
+params[7].tinyint_unsigned([3, 4, None])
+params[8].smallint_unsigned([3, 4, None])
+params[9].int_unsigned([3, 4, None])
+params[10].bigint_unsigned([3, 4, None])
+params[11].float([3, None, 1])
+params[12].double([3, None, 1.2])
+params[13].binary(["abc", "dddafadfadfadfadfa", None])
+params[14].nchar(["涛思数据", None, "a long string with 中文字符"])
+params[15].timestamp([None, None, 1626861392591])
 ```
 
-##### 获取消费进度
-
-Consumer API 的 `assignment` 方法用于获取 Consumer 订阅的所有 topic 的消费进度，返回结果类型为 TopicPartition 列表。
+调用 stmt 的 `bind_param` 以单行的方式设置 values 或 `bind_param_batch` 以多行的方式设置 values 方法绑定参数。
 
-```python
-assignments = consumer.assignment()
+```
+stmt.bind_param_batch(params)
 ```
 
-##### 指定订阅 Offset
+##### 执行 sql
 
-Consumer API 的 `seek` 方法用于重置 Consumer 的消费进度到指定位置，方法参数类型为 TopicPartition。
+调用 stmt 的 `execute` 方法执行 sql
 
-```python
-tp = TopicPartition(topic='topic1', partition=0, offset=0)
-consumer.seek(tp)
+```
+stmt.execute()
 ```
 
-##### 关闭订阅
+##### 关闭 stmt
 
-消费结束后，应当取消订阅，并关闭 Consumer。
+最后需要关闭 stmt。
 
-```python
-consumer.unsubscribe()
-consumer.close()
 ```
