How to debug a 'can't set attribute' error

An order object have different task objects, within each task I need to keep track of the order also. Indeed, I will define different orders later. I defined the following classes.

How to fix this?

You have a property and class attribute with the same name in the Task class. Since you haven't defined a setter for the command property, you get this error.

To fix this, you should probably make the Task class store the command in an attribute with a different name and add a setter, perhaps something along the lines of:

class Task:
    def __init__(self, ..., command):
        # some init stuff ...
        self._command = command

    @property
    def command(self):
        # sanity check here...
        return self._command

    @command.setter
    def command(self, x):
        self._command = x

Or if you don't want the command property changed after the task is created, just leave out the setter.
