## Installation
## Installation Steps
### 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.

### Subscription
### Writing data via parameter binding
Connector support data subscription. For more information about subscroption, please refer to [Data Subscription](../../../develop/tmq/).
The Python connector provides a parameter binding api for inserting data. Similar to most databases, TDengine currently only supports the question mark `?` to indicate the parameters to be bound.
<Tabs defaultValue="native">
<Tabs>
<TabItem value="native" label="native connection">
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"})
```
import taos
##### 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
```python
while True:
res = consumer.poll(1)
if not res:
continue
err = res.error()
if err is not None:
raise err
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
assignments = consumer.assignment()
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])
```
##### Seek
The `seek` function is used to reset the assignment of the topic.
Call the `bind_param` (for a single row) method or the `bind_param_batch` (for multiple rows) method to set the values.
```python
tp = TopicPartition(topic='topic1', partition=0, offset=0)
consumer.seek(tp)
```
stmt.bind_param_batch(params)
```
##### After consuming data
##### execute sql
You should unsubscribe to the topics and close the consumer after consuming.
Call `execute` method to execute sql.
```python
consumer.unsubscribe()
consumer.close()
```
stmt.execute()
```
##### Tmq subscription example
##### Close Stmt
```python
{{#include docs/examples/python/tmq_example.py}}
```

</TabItem>
<TabItem value="websocket" label="WebSocket connection">
In addition to native connections, the connector also supports subscriptions via websockets.
##### Create Consumer
##### Create Stmt
The syntax for creating a consumer is "consumer = consumer = Consumer(conf=configs)". You need to specify that the `td.connect.websocket.scheme` parameter is set to "ws" in the configuration. For more subscription api parameters, please refer to [Data Subscription](../../../develop/tmq/#create-a-consumer).
Call the `statement` method in `Connection` to create the `stmt` for parameter binding.
```python
```
import taosws
consumer = taosws.(conf={"group.id": "local", "td.connect.websocket.scheme": "ws"})
conn = taosws.connect('taosws://localhost:6041/test')
stmt = conn.statement()
```
##### subscribe topics
##### Prepare sql
The `subscribe` function is used to subscribe to a list of topics.
Call `prepare` method in stmt to prepare sql.
```python
consumer.subscribe(['topic1', 'topic2'])
```
##### 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.
```python
while True:
res = consumer.poll(timeout=1.0)
if not res:
continue
err = res.error()
if err is not None:
raise err
for block in message:
for row in block:
print(row)
stmt.prepare("insert into t1 values (?, ?, ?, ?)")
```
##### assignment
##### parameter binding
The `assignment` function is used to get the assignment of the topic.
Call the `bind_param` method to bind parameters.
```python
assignments = consumer.assignment()
```
stmt.bind_param([
taosws.millis_timestamps_to_column([1686844800000, 1686844801000, 1686844802000, 1686844803000]),

])
```
##### Seek
The `seek` function is used to reset the assignment of the topic.
Call the `add_batch` method to add parameters to the batch.
```python
consumer.seek(topic='topic1', partition=0, offset=0)
```
stmt.add_batch()
```
##### After consuming data
##### execute sql
You should unsubscribe to the topics and close the consumer after consuming.
Call `execute` method to execute sql.
```python
consumer.unsubscribe()
consumer.close()

`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()
```
##### 完整示例
```python
{{#include docs/examples/python/tmq_example.py}}
stmt.close()
```

<TabItem value="websocket" label="WebSocket 连接">
除了原生的连接方式，Python 连接器还支持通过 websocket 订阅 TMQ 数据，使用 websocket 方式订阅 TMQ 数据需要安装 `taos-ws-py`。
taosws `Consumer` API 提供了基于 Websocket 订阅 TMQ 数据的 API。
##### 创建 Consumer
##### 创建 stmt
创建 Consumer 语法为 `consumer = Consumer(conf=configs)`，使用时需要指定 `td.connect.websocket.scheme` 参数值为 "ws"，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)。
Python WebSocket 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。
```python
```
import taosws
consumer = taosws.(conf={"group.id": "local", "td.connect.websocket.scheme": "ws"})
conn = taosws.connect('taosws://localhost:6041/test')
stmt = conn.statement()
```
##### 订阅 topics
##### 解析 sql
Consumer API 的 `subscribe` 方法用于订阅 topics，consumer 支持同时订阅多个 topic。
调用 stmt 的 `prepare` 方法来解析 insert 语句。
```python
consumer.subscribe(['topic1', 'topic2'])
```
stmt.prepare("insert into t1 values (?, ?, ?, ?)")
```
##### 消费数据
##### 参数绑定
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。
调用 stmt 的 `bind_param` 方法绑定参数。
```python
while True:
res = consumer.poll(timeout=1.0)
if not res:
continue
err = res.error()
if err is not None:
raise err
for block in message:
for row in block:
print(row)
```
stmt.bind_param([
taosws.millis_timestamps_to_column([1686844800000, 1686844801000, 1686844802000, 1686844803000]),
taosws.ints_to_column([1, 2, 3, 4]),
taosws.floats_to_column([1.1, 2.2, 3.3, 4.4]),
taosws.varchar_to_column(['a', 'b', 'c', 'd']),
])
```
##### 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 `add_batch` 方法，将参数加入批处理。
```python
assignments = consumer.assignment()
```
stmt.add_batch()
```
##### 重置消费进度
##### 执行 sql
Consumer API 的 `seek` 方法用于重置 Consumer 的消费进度到指定位置。
调用 stmt 的 `execute` 方法执行 sql
```python
consumer.seek(topic='topic1', partition=0, offset=0)
```
stmt.execute()
```
##### 结束消费
##### 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()
```
##### tmq 订阅示例代码
```python
{{#include docs/examples/python/tmq_websocket_example.py}}
