这是我的代码：
我导入模块

import shodan
import json

我创建了我的密钥，

SHODAN_API_KEY = ('xxxxxxxxxxxxxxxxxxxx')
api = shodan.Shodan(SHODAN_API_KEY)

我打开我的json文件，

with open('Ports.json', 'r') as f:
    Ports_dict = json.load(f)
    #I loop through my dict,
    for Port in Ports_dict:
        print(Port['Port_name'])
       
        try:
            results = api.search(Port['Port_name']) # how can I filter ports by country??
            #and I print the content.
            print('Results found: {}'.format(results['total']))
            for result in results['matches']:
                print('IP: {}'.format(result['ip_str']))
                print(result['data'])
                print('')
                print ('Country_code: %s' % result['location']['country_code'])
            
        except shodan.APIError as e:
                print(' Error: %s' % e)

但如何按国家/地区筛选端口？
