To get use what this returns:
    lat = str(int(gps.latitude))
    lng = str(int(gps.longitude))
    if lat[0] == '-':
        print('lat={}.{}'.format(lat[:3],lat[3:]))
    else:
        print('lat={}.{}'.format(lat[:2],lat[2:]))
    if lng[0] == '-':
        print('lng={}.{}\n'.format(lng[:3],lng[3:]))
    else:
        print('lng={}.{}\n'.format(lng[:2],lng[2:]))
