什么是域名删除时间

import whois

def get_domain_deletion_date(domain_name):
    try:
        w = whois.whois(domain_name)
        if hasattr(w, 'expiration_date'):
            # 假设域名在到期后7天被删除
            deletion_date = w.expiration_date[0] + timedelta(days=7)
            return deletion_date
        else:
            return "Deletion date not available"
    except Exception as e:
        return str(e)

# 使用示例
domain_name = "example.com"
deletion_date = get_domain_deletion_date(domain_name)
print(f"The deletion date for {domain_name} is: {deletion_date}")
