exceptions need a common base class

[foresto]

All the exceptions in the braintree package derive directly from Exception, which makes them indistinguishable from standard python exceptions unless I write special cases for each one of them (and hope new ones never show up). For example:

try:
    braintree.Customer.create( dict( first_name="John", last_name="Doe"))
except (AuthenticationError, 
    AuthorizationError, 
    DownForMaintenanceError,
    ForgedQueryStringError,
    NotFoundError,
    ServerError,
    UnexpectedError,
    UpgradeRequiredError):
    print "braintree raised an exception"

All these exception classes really need a common ancestor that doesn't belong to the python standard library. braintree.Error, perhaps.

Thanks for the suggestion. We added a common exception ancestor which will be released in the next version. If you would like to be notified when we release, please sign up at http://www.braintreepaymentsolutions.com/gateway/gateway-updates
