+### 通过参数绑定写入数据
+
+TDengine 的 Python 连接器支持参数绑定风格的 Prepare API 方式写入数据，和大多数数据库类似，目前仅支持用 `?` 来代表待绑定的参数。
+
+<Tabs>
+<TabItem value="native" label="原生连接">
+
+#### 创建 stmt
+
+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。
+
+```
+import taos
+
+conn = taos.connect()
+stmt = conn.statement("insert into log values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)")
+```
+
+#### 参数绑定
+
+调用 `new_multi_binds` 函数创建 params 列表，用于参数绑定。
+
+```
+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[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])
+```
+
+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。
+
+```
+stmt.bind_param_batch(params)
+```
+
+#### 执行 sql
