The WingIDE guys probably just forgot to include it. Python is very strange in that if you convert an exception to a string, it doesn't tell you what exception type was thrown! So, for example, this is not sufficient:
except Exception, e:
print 'Caught exception: %s' % e
Instead, it needs to be:
print 'Caught exception: %s: %s' % (e.__class__.__name__, e)
Feels like an oversight in the design of exceptions in my opinion, but it's the way that it is. I even have a function for it:
Return a readable string for an exception. Format is:
if not e:
return '%s: %s' % (e.__class__.__name__, e)
