Question

我有一些错误处理的Python代码，但由于某些原因，代码似乎仍然无法处理这个特定的错误：

raise GQueryError("No corresponding geographic location could be found for the     specified location, possibly because the address is relatively new, or because it may be incorrect.")
geopy.geocoders.google.GQueryError: No corresponding geographic location could be found for the specified location, possibly because the address is relatively new, or because it may be incorrect.

这是来源：

import csv
from geopy import geocoders
import time

g = geocoders.Google()

spamReader = csv.reader(open('locations.csv', 'rb'), delimiter='\t', quotechar='|')

f = open("output.txt",'w')

for row in spamReader:
    a = ', '.join(row)
    #exactly_one = False
    time.sleep(1)

    try:
        place, (lat, lng) = g.geocode(a)
    except ValueError:
        #print("Error: geocode failed on input %s with message %s"%(a, error_message))
        continue 

    b = str(place) + "," + str(lat) + "," + str(lng) + "\n"
    print b
    f.write(b)

我没有包含足够的错误处理吗？我的印象是＆＃34;除了ValueError＆＃34;会处理这种情况，但我一定是错的。

提前感谢您的帮助！

P.S。我把它从代码中删除了，但我不知道它到底意味着什么：

   def check_status_code(self,status_code):
    if status_code == 400:
        raise GeocoderResultError("Bad request (Server returned status 400)")
    elif status_code == 500:
        raise GeocoderResultError("Unkown error (Server returned status 500)")
    elif status_code == 601:
        raise GQueryError("An empty lookup was performed")
    elif status_code == 602:
        raise GQueryError("No corresponding geographic location could be found for the specified location, possibly because the address is relatively new, or because it may be incorrect.")
    elif status_code == 603:
        raise GQueryError("The geocode for the given location could be returned due to legal or contractual reasons")
    elif status_code == 610:
        raise GBadKeyError("The api_key is either invalid or does not match the domain for which it was given.")
    elif status_code == 620:
        raise GTooManyQueriesError("The given key has gone over the requests limit in the 24 hour period or has submitted too many requests in too short a period of time.")

现在try / except只捕捉ValueError s。要同时捕获GQueryError，请将except ValueError:行替换为：

except (ValueError, GQueryError):

或者如果GQueryError不在你的命名空间中，你可能需要这样的东西：

except (ValueError, geocoders.google.GQueryError):

或者捕获ValueError以及check_status_code中列出的所有错误：

except (ValueError, GQueryError, GeocoderResultError, 
        GBadKeyError, GTooManyQueriesError):

（同样，如果错误位置不在您的命名空间中，请将geocoders.google.或错误位置添加到所有地理错误的前面。）

或者，如果您只想捕获所有可能的异常，您可以这样做：

except:

但这通常是不好的做法，因为它也会在你的place, (lat, lng) = g.geocode(a)行中发现语法错误，你不想抓住它，所以最好检查一下geopy代码来找到所有的它可能会抛出你想抓住的可能例外。希望所有这些都列在你找到的那段代码中。
