From the examples it is expected that obj['error'] is always set

[elchiapp]

Hi, thanks for this great library. I just wanted to report a behavior that, in my opinion, is not very obvious: in the examples it is shown that to check for errors it's enough to check whether obj['error'] is True. But when the request is successful the key 'error' is not set at all which might lead to a KeyError.

Is there a reason why obj['error'] is not set to False if the request is successful instead of not being set at all? I would expect this behavior for error_code not for just error.

Thank you.

You might try using:

if 'error' in obj:

instead?

Yes and that would technically, not conceptually, solve the problem. What I'm trying to say is that a first-time user of the library might not expect this behavior. Maybe this is a common good practice or pattern (apologies in case).
