Hi all,
I was trying to share a dictionary of dictionaries of arrays with
Manager from multiprocessing. Without multiprocessing the code works
perfectly, but with the current example the last print does not show
the correct result.
Any hint?
Thanks,

You can't sort dictionaries in Python, because they are unordered hash
tables. Giving up the ability to store items in order is one of the
things

Python's built-in dictionary is unsorted by design.

Ah, thank you, you explained that quite well and opened my eyes to some
things I very much need to improve in my code. I'll keep those
list-etiquette things in mind next time.

I've been using irclib to write a simple irc bot, and I was running into
some difficulties with pickle. Upon some experimentation with pdb, I found
that pickle.load() doesn't load *all* of the data the _first_ time it's
called.
For instance, I have this dictionary pickled:

Hi,
I'm wondering what the best practice is for creating an extensible
dictionary-of-dictionaries in python?
In perl I would just do something like:
my %hash_of_hashes;
for(my $i=0;$i<10;$i++){
for(my $j=0;$j<10;$j++){
${$hash_of_hashes{$i}}{$j} = int(rand(10));

This creates two references to just *one* instance of empty
dictionary.
I'd do it like:
messagesReceived = dict([(key, {}) for key in ("one","two")])

`dict.fromkeys()` stores the given object for all keys, so you end up with
the *same* dictionary for 'one' and 'two'.
In [18]: a = dict.fromkeys(("one","two"), {})
In [19]: a
Out[19]: {'two': {}, 'one': {}}
In [20]: a['one']['x'] =

This will create a dictionary "messagesReceived", with all the keys
referring to *same instance* of the (empty) dictionary.
( try: m
Hi,
I have the following -
messagesReceived = dict.fromkeys(("one","two"), {})
messagesReceived['one']['123'] = 1
messagesReceived['two']['121'] = 2
messagesReceived['two']['124'] = 4
This gives:
{'two': {'121': 2, '123': 1, '124': 4}, 'one': {'121':
2, '123': 1
22 matches
