语法错误运行python文件时？

Question

我是python的新手所以请忽略，如果这是愚蠢的。在这里，我在以某种指定格式打印数据时获得无效语法。

with open("ip_services.xyz", "w") as handle:
    for service in sorted(...some functionality...)):
        print("ip_server(\"{}\", {}, {}, {}, {}, {}, {}) # {}, {}".format(
            service.address, service.port, 1 if service.udp else 0,
            service.service_id, service.instance_id,
            service.major_version, service.minor_version,
            service.xyz,
            service.service_name),
              file=handle)

错误就像： -

  File "producer.py", line 220
    print("{} = \"{}\" # {}".format(signal, value, label), file=handle)
                                                               ^
SyntaxError: invalid syntax
