ow wxpython works in this regard.
So:
s = u"Matični broj" # instead of "Matični broj"
text = wx.StaticText(self, -1, s,(0,100))
# or if that doesn't work try this:
#text = wx.StaticText(self, -1, s.encode('utf-8'), (0,100))

For the reasons already stated, I think it's probably a bad idea to
enforce this at compile time. I think it's a great idea to make sure
that this information is present in all your code, but unless you want
to see useless stubs, the correct time to enforce this is at commit
time. Don't accept any improperly documented patches.
Syntax is not enough to ensure what you want to ensure. The semantics
have to be right as well.

chooses to recursively call __str__ on its elements, it is free to do
so, but since that causes ambiguity (as many people have pointed out),
python has (wisely) chosen to use repr instead. If I wanted to
implement a list-like class that doesn't show it's elements at all when
printed, but instead shows its length, I am free to do so.
For example:
>>> hl = HiddenList(1,2,3)
>>> hl
>>> hl[1]
2
(Implementation of HiddenList left as an exercise for the reader.)
If you want to implement a list-like object that returns the str of its
elements, go right ahead, or implement a function that digs into
containers and creates its own list representation for them. But that's
not how python works by default, nor should it be, for reasons already
explained by others.

Interesting. I hadn't thought of making __call__ a synonym for an
existing method. I think I like that, but I'm not quite sure. There's
something that nags at me about having two ways to do the same thing,
but I like giving the method a more descriptive name than __call__.

Essentially, this has the same behavior as the other two. But it looks
cleaner, and you don't have to worry about coupling separate functions,
or refering to a function by name within itself (because you have self
to work with). But the "object" semantics are essentially the same, and
state is just as legitimately preserved on a function object as a Foo
object.

So what you are seeing is best thought of as two garbage characters, one
of which happens (by coincidence only) to be the same as your original
character. If you decode the bytes returned properly (as UTF-8), you
will get the bytes you put in, for all characters.

This is definitely not functional code, but might get you in the right

haven't worked too much

self.y = 5
class B(object):
x = u'cow'
def __init__(self):
self.y = u'goat'
>>> c = A()

4
>>> c.y
5
>>> c.__class__ = B
>>> # Note that neither c nor x were changed in the last step

u'cow'

u'goat'

The important thing is that when you call x.__iter__() (which you do

Any one of these seems like a better idea to me than trying to pollute

No. __init__ should not return anything (rather, it should return None,
but it'll do that on its own without you telling it to return anything).
The problem is that you are trying to create an object with __init__,
but that is not what it does. It *initializes* objects that already
exist. when you call a class, it creates a new instance using
__new__(), and then initializes it using __init__(). So if you were
really inclined to muck around. You could do something like
cust1 = Customer.__new__(Customer)
cust1.__init__('12', ['1','435', '2332'])
But that would just be silly. What you really want is this:
cust1 = Customer('12', ['1','435', '2332'])
which does the same thing. Don't explicitly call under-under variables
unless you really have to.

Sounds like a good strategy would be to find the smallest chunk of the
file that matches can't cross, and iterate your search on units of those
chunks. For example, if none of your regexes cross line boundaries,
search each line of the file individually. That may help turn around
the speed degradation you're seeing.

In Evolution this is as easy as right clicking on a message from the
list in your inbox, select "Create Rule From Message > Filter on Mailing
List", and then choose a folder to redirect to.
Reading by thread instead of by
to open newfile in any piece of software of your choosing.
It's no longer a well-formed jpeg, so it won't work. That's exactly
what you're asking the browser to do.
I guess this isn't really python related, so my apologies for that.

Another possibility is to assign to a dict using a loop, if typing None
over and over again is so onerous.
options = ['cache_control',
'connection',
'date',
'pragma']
params = {}
for option in options:
params[option] = None
And of course you could substitute your choice of appropriate __dict__
for params, if you want to access the options as free-standing objects.

I was with you on this issue right up until that last paragraph. You

If you add that print line to end of your original code, then you'll get
the z%4-th element of bg, which would be one character, because bg is a
string, but if you "define bg as a list of the four colours" first, as
instructed, you'll get sensible results:
bg = ['#ff', '#b2b2b2', '#33FF66', '#00']
for z in (0,1,2,3,4,5,6,7,8,9):

trying to catch, it's better to leave off the try/except block,
*especially* during development. Stack traces are full of good
information.
Second, you never initialize w, which causes the following problem.
$ python

Type "help", "copyright", "credits" or "license" for more information.
>>> w += 1
Traceback (most recent call last):
File "", line 1, in ?

Third, double-spacing your code makes it difficult to read. Take out
blank lines, unless they add contextual hints which improve readability.
Post working code, and I'll answer your actual question.

You rebind the name system.thing, but the object it was originally bound
to is unaffected. Strings are immutable, so you couldn't change that
object if you tried. thing is still bound to the original object.
Another feature of this behavior is as follows:

A colon on the correct line would help readability quite a bit.
Yeah, I know I made it pretty ugly to begin with, and there are ways to
improve it without the colon, but still, just because it could be
removed doesn't necessarily mean it should.

un on 8084, you can
do the following

port = {

'dev.example.com': 8084,

It's a handy idiom.

practice. You leave yourself vulnerable not only
to attacks, but to simple absent-mindedness as well. Using parameters
in your execute statement will handle all necessary quoting for you,
which eliminates the possibility of a bad query sneaking in. For more

The problem is that the class of platform.__builtins__ is a dict, not a
string containing the text "".
Try replacing line 16 with this:
self.assertEqual(type(platform.__builtins__), dict)

Admittedly, this is a trivial benefit. If you're using a literal, you
