Python try语句使用谷歌地图1.0.2

我使用的是python模块googlemaps 1.0.2，不能在用户输入未知地址的实例中使用try语句

我收到的错误消息如下所示：

GoogleMapsError: Error 602: G_GEO_UNKNOWN_ADDRESS

我的方法如下所示（没有API密钥）：

我试过：

except GoogleMapsError:
except 'GoogleMapsError: Error 602: G_GEO_UNKNOWN_ADDRESS'

谢谢

您可能尚未导入googlemaps.GoogleMapsError异常

from googlemaps import GoogleMaps, GoogleMapsError

def get_distance(address, destination):
    try:
        gmaps = GoogleMaps(api_key)
        directions = gmaps.directions(address,destination)
        distance = directions['Directions']['Distance']['meters']/1600.0
        return distance
    except GoogleMapsError:
        pass

从googlemaps导入googlemaps，GoogleMapsError

？？？

from googlemaps import GoogleMaps, GoogleMapsError

def get_distance(address, destination):
    try:
        gmaps = GoogleMaps(api_key)
        directions = gmaps.directions(address,destination)
        distance = directions['Directions']['Distance']['meters']/1600.0
        return distance
    except GoogleMapsError:
        pass
