tweepy/ twitter api error type

Question

I am using tweepy to make a twitter application. When users tweet/update profile, etc, they will get some errors. I want to classify error and give user more information.

try:
    tweet/update profile/ follow....

except tweepy.TweepError, e:

    if tweepy.TweepError is "Account update failed: Description is too long (maximum is 160 characters)"
        Do something
    if tweepy.TweepError is "Failed to send request: Invalid request URL: http://api.twitter.com/1/account/update_profile.json?location=%E5%85%B5%E5%BA%A"
        Do something
    if tweepy.TweepError is "[{u'message': u'Over capacity', u'code': 130}]" 
        Do something

Is the only way to classify error is to compare e with string, for example, Account update failed: Description is too long (maximum is 160 characters)?

Answer 1

Right, it is the only way now. There is only one TweepError exception defined. It's raised throughout the app with different text.

Here's the relevant open issue on github. So there is a chance that it'll be improved in the future.
