我是Python 2.7的新手.我正在编写一个程序,在我继续使用Internet将数据发送到数据库之前,我需要检查我的Wifi的互联网可用性(有时是互联网断开连接).如果没有互联网连接,将跳过向数据库发送数据.我怎样才能做到这一点.这是我这样做的正确方法吗？

import urllib                                                        
#Perhaps check internet availability first

        conn.close()
        return True
    except:
        conn.close()
        return False


#send data to database
data = {'date':date_mmddyyyy,'time':time_hhmmss,'airtemperature':temperature_c,'humidity':humidity_c, 'watertemperature':watertemp_c, 'phsolution':pHvalue_c, 'waterlevel':distance_c, 'CO2 concentration':CO2_c, 'TDS value':tds_c}
result = firebase.put('Region 1', 'Parameter Reading', {'date':date_mmddyyyy,'time':time_hhmmss,'airtemperature':temperature_c,'humidity':humidity_c, 'watertemperature':watertemp_c, 'phsolution':pHvalue_c, 'waterlevel':distance_c, 'CO2 concentration':CO2_c, 'TDS value':tds_c})
result2 = requests.post(firebase_url + '/' + reading_location + '/History/Parameter Reading.json', data=json.dumps(data))     
print 'All parameter records are inserted.\nResult Code = …
