Requirement already satisfied: pymodbus[full] in c:\program files (x86)\microsoft visual studio\shared\python39_64\lib\site-packages (3.3.1) WARNING: pymodbus 3.3.1 does not provide the extra 'full'

根据你的提示信息,`pymodbus`模块已经被安装了,并且版本为3.3.1。另外,你还可以看到一个警告,该警告指出该版本的`pymodbus`模块不提供名为`full`的额外选项。
这意味着,你不需要再次安装`pymodbus`模块或指定`full`选项,因为你已经安装了最新版本的模块。你可以在Python脚本中直接导入`pymodbus.client.sync`模块,并开始使用Modbus TCP协议进行同步通信:
```python
from pymodbus.client.sync import ModbusTcpClient
# 创建一个Modbus TCP客户端对象
client = ModbusTcpClient('127.0.0.1', port=502)
# 连接到Modbus TCP服务器
client.connect()
# 发送读取保持寄存器的请求
response = client.read_holding_registers(address=0, count=10, unit=1)
# 获取响应数据
if response.isError():
print("Error: %s" % response)
else:
print(response.registers)
# 关闭连接
client.close()
```

看起来您已经成功安装了 Flask。接下来可以创建一个简单的 Flask 应用程序。您可以在 Python 中创建一个新文件,然后将以下代码复制到该文件中:
```
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello():
return 'Hello, World!'
```
这个应用程序非常简单,它只有一个路由 '/',当访问该路由时,它会返回 'Hello, World!'。现在,您可以运行这个应用程序。在命令提示符中输入以下命令:
```
export FLASK_APP=yourfilename.py
flask run
```
这会启动 Flask 开发服务器,并在默认情况下监听本地主机的端口 5000。现在您可以在浏览器中访问 `http://localhost:5000/`,应该会看到 'Hello, World!' 的消息。
