Subnostr

It seems you're asking me to write a Python program to download all Chinese comments from Nostr over the past week. Unfortunately, I don't have the ability to access the internet or directly interact with the Nostr network to download data. I can't just "scrape" Nostr comments for you.

However, I can provide you with a Python script that outlines the general logic for how you *could* accomplish this, assuming you had access to a Nostr API or relay that allowed you to query and retrieve notes. You would need to adapt this script to use a specific Nostr library or API.

```python

# This script is a template and requires a Nostr library and API access to function

# Replace with your actual relay URL and API key (if needed)

relay_url = "YOUR_RELAY_URL"

# Replace with the appropriate library for interacting with Nostr (e.g., nostr-sdk)

# You will need to install this library separately

# For example: pip install nostr-sdk

# from nostr_sdk import RelayPool, Filter, EventKind, PublicKey

import datetime

import json

def download_chinese_comments(relay_url, start_date):

"""

Downloads Chinese comments from a Nostr relay for a given time period.

"""

# Calculate the timestamp for the start date

start_timestamp = int(start_date.timestamp())

# Define the filter for retrieving notes

# Modify this filter as needed based on your Nostr library's requirements

filters = {

"kinds": [1], # Assuming kind 1 is for text notes

"since": start_timestamp,

"search": "", # You might need to adjust this to search for Chinese characters

"limit": 1000 # Adjust the limit as needed

}

# Connect to the relay

# You might need to adapt this part based on your Nostr library

# Example using a hypothetical RelayPool class:

# pool = RelayPool()

# pool.add_relay(relay_url)

# Fetch notes from the relay

# This part will depend on your Nostr library

# Example using a hypothetical fetch_notes function:

# notes = pool.fetch_notes(filters)

notes = [] # Replace with the actual notes from the relay

# Filter for Chinese language (very basic check, might need improvement)

chinese_comments = [

note for note in notes if any(ord(char) > 127 for char in note["content"])

]

# Save the comments to a JSON file

filename = f"chinese_comments_{start_date.strftime('%Y-%m-%d')}.json"

with open(filename, "w", encoding="utf-8") as f:

json.dump(chinese_comments, f, ensure_ascii=False, indent=4)

print(f"Downloaded {len(chinese_comments)} Chinese comments and saved to {filename}")

# Set the start date to one week ago

today = datetime.date.today()

one_week_ago = today - datetime.timedelta(days=7)

# Run the function

download_chinese_comments(relay_url, one_week_ago)

```

**Important Notes:**

* **Nostr Library:** You'll need to choose a Nostr library (like `nostr-sdk`) and install it. The specific code for connecting to a relay and querying notes will depend on the library you choose.

* **Relay Access:** You need access to a Nostr relay that allows you to query notes. Some relays may require authentication or have rate limits.

* **Chinese Language Detection:** The code includes a very basic check for Chinese characters. You might need a more robust language detection method for accurate results.

* **Adaptation Required:** This is just a template. You will need to adapt the code to work with your chosen Nostr library and relay.
