需要一个Python脚本来处理数据， 作为参数输入的nostr_id_public_keys_china_users.txt 文件的每一行为一个公钥id，需要读取每一行公钥id作为参数，比如 db11b32009d914dd76bd904b8a636627d1d9043f2a4f9ecaf6aaf85d05c5f7af ，拼接命令为 echo '["REQ", "cn", {"authors": ["db11b32009d914dd76bd904b8a636627d1d9043f2a4f9ecaf6aaf85d05c5f7af"] , "kinds": [1], "limit": 1}]'|nostcat wss://offchain.pub|jq '.[2].created_at' , 执行命令将获得的时间戳结果跟当前时间比较 ，如果小于30天则将公钥id 添加输出到 nostr_crawler_live_zh_users_list.txt 文件里，并依次循环执行。

result = subprocess.run(cmd, stdout=subprocess.PIPE, shell=True, text=True)
try:

except ValueError:
return None
def is_within_30_days(timestamp):
current_time = int(time.time())
return (current_time - timestamp) < (30 * 24 * 60 * 60)
with open(input_file, 'r') as f_in, open(output_file, 'w') as f_out:
