需要安装 python-whois 库：pip install python-whois

import whois
import time

# 域名前缀和后缀列表
prefixes = ["example", "test", "demo"]
suffixes = [".com", ".net", ".org", ".io"]

def is_domain_registered(domain):
    try:
        w = whois.whois(domain)
        # 如果返回的信息中有注册人、创建时间等字段，则认为已被注册
        return bool(w.registrar or w.creation_date or w.name_servers)
    except Exception as e:
        # 某些 TLD 可能抛出异常表示未注册
        print(f"Error checking {domain}: {e}")
        return False

# 批量检查
for prefix in prefixes:
    for suffix in suffixes:
        domain = f"{prefix}{suffix}"
        registered = is_domain_registered(domain)
        if not registered:
            print(f"[AVAILABLE] {domain}")
        else:
            print(f"[TAKEN] {domain}")
        
        # 防止请求太频繁
        time.sleep(1)
