Why am I getting AttributeError: Object has no attribute [closed]

Answer 1

I have encountered the same error as well. I am sure my indentation did not have any problem. Only restarting the python sell solved the problem.

Answer 2

I got this error for multi-threading scenario (specifically when dealing with ZMQ). It turned out that socket was still being connected on one thread while another thread already started sending data. The events that occured due to another thread tried to access variables that weren't created yet. If your scenario involves multi-threading and if things work if you add bit of delay then you might have similar issue.

Answer 3

Python protects those members by internally changing the name to include the class name. You can access such attributes as object._className__attrName.
