QUESTION
I'm using Fysom
to create a finite state machine in Python, and I'm seeing one issue which I don't know why it's happening.
I create a MyClass
class, and inside that class I create a self.fsm
member which is an instance of Fysom
.
For some reason, the fsm
member of my class seems to not exist when the first state of the finite state machine is reached. But when the second state is reached, it does exist.
ANSWER
Answered 2017-Dec-07 at 21:17You guess is correct and it's the correct behavior. __init__
is executed in order. Your callback happens when the fsm is created and before it's assigned to self.fsm
, so self.__dict__
is still empty.
After you've successfully instantiated and assigned the fsm, you could initialize it within the __init__

Install fysom
You can use fysom like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
