def geocode(address):
        parameters = {'key': 'ca46ec1d11040999ec4b02d9b8a64a4c','address': address}
        base = 'https://restapi.amap.com/v3/geocode/geo?parameters'
        response = requests.get(base, parameters)
        answer = response.json()
        print(answer)
        dz=answer['geocodes'][0]['formatted_address']
        qu=answer['geocodes'][0]['city']+answer['geocodes'][0]['district']
        adcode=answer['geocodes'][0]['adcode']
        location=answer['geocodes'][0]['location']
        return dz,qu,adcode,location
