i am trying to migrate an application from gtk2 to gtk3 using GObject Introspection (gi.repository).
The problem i have now is creating an Atk.Relation in an accessibility method that looks like this:
from gi.repository import Atk
def atk_acc(obj, lbl):
atk_obj = obj.get_accessible()
atk_l = lbl.get_accessible()
relation_set = atk_l.ref_relation_set()
relation = Atk.Relation.new([atk_obj], 1, Atk.RelationType.LABEL_FOR)
relation_set.add(relation)
When i run the application, it breaks with an exception:
Traceback (most recent call last):
File "/home/erick/Desarrollo/git/canaima-instalador/canaimainstalador/main.py", line 237, in siguiente
CFG['w'].next('Metodo', Metodo, (CFG), PasoMetodo(CFG))

relation = Atk.Relation.new([atk_obj], 1, Atk.RelationType.LABEL_FOR)
File "/usr/lib/python2.7/dist-packages/gi/types.py", line 72, in constructor
return info.invoke(cls, *args, **kwargs)
TypeError: Expected Atk.Object, but got GObjectMeta
In ATK documentation says that the first argument of Atk.Relation.new is an array.
What i'm doing wrong here?

I installed chatterbot in my terminal earlier today using virtual studio code's terminal. I saw that both chatterbot and chatterbot_corpus worked in installation. Then, I made the following python document:
EDIT: Turns out I should define a chatbot variable first.
from chatterbot import ChatBot
from chatterbot.trainers import ChatterBotCorpusTrainer
from chatterbot.trainers import ListTrainer
conversation = [
"Hello",
"Hi there!",
"How are you doing?",
"I'm doing great.",
"That is good to hear",
"Thank you.",
"You're welcome."
]
bot = ChatBot('Maya')
trainer = ListTrainer(bot)
trainer.train(conversation)
This was my code
it says this however
bot = ChatBot('Maya')

Does anyone know how to fix this easily?
EDIT: I just updated python using pip install --upgrade ipython in terminal, but it didn't fix the issue

But now it gives

it seems the python upgrade worked with regard to the initial error on time.clock. This new error you are seeing is quite different to the previous one. In this case you need to go into chatterbot/storage/sql_storage.py and comment out if not self.engine.dialect.has_table(self.engine, 'Statement'): and leave only self.create_database(). This means that instead of checking whether a database table has been created which is triggering the error, it will just create the DB every time, which i expect to work fine.
# if not self.engine.dialect.has_table(self.engine, 'Statement'):
self.create_database()

Try to install an older version of pymongo (preferably 2.9.0).

I am trying to get going with django, which so far I have found to be amazing other than repeated db issues.
My latest is following the Django by Example book and I have followed everything to the letter, yet when following some simple instructions to add some data via the python shell api I get the following:
>>> from django.contrib.auth.models import User
>>> from blog.models import Post
>>> user = User.objects.get(username='jamie')
>>> Post.objects.create(title='One More Post', slug='one-more-post', body='Post body', author='user')

During handling of the above exception, another exception occurred:

This has happened while following multiple tutorials and I am stumped. I followed standard instructions and installed, pip, python and django via terminal. Also using a virtual env so not sure why this is happening.
Use this instead of your statement.
Use user variable instead of 'user' string.
Post.objects.create(title='One More Post', slug='one-more-post',
body='Post body', author=user)
import blinker
from blinker import signal
class Ticket():
#classmethod
def update(cls):
pass
ticket_created = signal('CREATED')
ticket_created.connect(Ticket.update)
This snippet of code works well on Python 2.7. But does not work on Python 2.6. I get this trace:

Is there a way I could get this to work in 2.6 environment?
Yes, new-style classes is the answer.
class Ticket(object):

Solves the issue.
I am having an issue with Python throwing an AttributeError on accessing a variable.
The code is below, redacted for clarity.
class mycollection(object):
"""
Collection of stuff.

__slots__ = ["stuff_list"]
def __init__(self):
self.stuff_list = []
def add_stuff(self, stuff):
self.stuff_list.append(stuff)
#later on..
collection = mycollection()
stuff = stuff()
collection.add_stuff(stuff)
Generating this error.

Checking through the documentation, I don't understand why this error is arising.
__ini__ should be __init__
Wouldn't this be "more Pythonic"?
collection.stuff_list.append(test_stuff)
