User: 1738375477415のようなタイムスタンプを出力したいです　
Assistant: 1738375477415 のようなタイムスタンプは、Unixエポック（1970年1月1日00:00:00 UTC）からのミリ秒数を表しています。このようなタイムスタンプをPythonで生成するには、標準ライブラリの `time` または `datetime` モジュールを使用することができます。

以下に、現在の日時のミリ秒単位のUnixタイムスタンプを出力する簡単なPythonスクリプトを示します。

```python
import time

# 現在の時間をミリ秒単位で取得
timestamp_ms = int(time.time() * 1000)
print(timestamp_ms)
```

このスクリプトを実行すると、1970年1月1日からの経過時間をミリ秒単位で表したタイムスタンプが表示されます。

`datetime` モジュールを使用する場合は、以下のように記述できます。

```python
from datetime import datetime

# 現在の日時を取得
now = datetime.now()

# UNIXエポックからのミリ秒単位のタイムスタンプを計算
timestamp_ms = int(now.timestamp() * 1000)
print(timestamp_ms)
```

どちらの方法でも、1738375477415 のような形式のタイムスタンプを取得することができます。
User: python3 websockets
Assistant: Python's `websockets` library is great for creating WebSocket servers and clients in Python. It allows you to handle real-time communication over the web. Here's a basic example of how to create both a WebSocket server and client using this library:

### Installation
First, you need to install the `websockets` library if you haven't already. You can do this using pip:

```bash
pip install websockets
```

### WebSocket Server Example
Here's a simple WebSocket server that echoes back any message it receives:

```python
import asyncio
import websockets

async def echo(websocket, path):
    async for message in websocket:
        await websocket.send(f"Echo: {message}")

start_server = websockets.serve(echo, "localhost", 8765)

asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()
```

### WebSocket Client Example
And here's a simple WebSocket client that connects to the server and sends a message:

```python
import asyncio
import websockets

async def hello():
    uri = "ws://localhost:8765"
    async with websockets.connect(uri) as websocket:
        message = "Hello, WebSocket!"
        await websocket.send(message)
        response = await websocket.recv()
        print(response)

asyncio.get_event_loop().run_until_complete(hello())
```

### Explanation
- **Server**: The server listens on `localhost` at port `8765`. The `echo` function receives messages and sends them back to the client prefixed with "Echo: ".
- **Client**: The client connects to the server at `ws://localhost:8765`, sends a message "Hello, WebSocket!", and prints the server's response.

With these examples, you can start creating real-time web applications using WebSockets in Python. Let me know if you have any specific questions or need further assistance!

Assistant: When working with WebSockets in Python, you might want to include custom headers in your WebSocket client for various reasons such as authorization, session management, etc. The `websockets` library allows you to include headers in the client connection.

### Example with Custom Headers

Below is an example that demonstrates how to add custom headers to your WebSocket client connection:

### WebSocket Server Example (from previous message)

```python
import asyncio
import websockets

async def echo(websocket, path):
    async for message in websocket:
        await websocket.send(f"Echo: {message}")

start_server = websockets.serve(echo, "localhost", 8765)

asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()
```

### WebSocket Client with Custom Headers

```python
import asyncio
import websockets

async def hello():
    uri = "ws://localhost:8765"
    headers = {
        "Authorization": "Bearer your_token_here",
        "Custom-Header": "YourCustomValue"
    }
    
    async with websockets.connect(uri, extra_headers=headers) as websocket:
        message = "Hello, WebSocket!"
        await websocket.send(message)
        response = await websocket.recv()
        print(response)

asyncio.get_event_loop().run_until_complete(hello())
```

### Explanation

- In the `hello()` function, we define a dictionary `headers` that contains the custom headers we want to send.
- When establishing a connection with `websockets.connect`, we pass the `extra_headers` parameter with our headers dictionary.

This way, you can include any custom headers you need when connecting to a WebSocket server. The server can then read these headers and perform actions such as authentication or logging based on the header values.

Feel free to let me know if you need further clarifications or additional examples!
