You should use thread.start(), not thread.run(). When you use run(), it

There is a discussion about this in the thread `Threaded
As I said above you should do the SMTP connection setup, including the
login, here, and store the connection either in self.s or in a local
variable s in the method. As you don't use the s in another method, I
think a local variable is better.

econd, the mail server probably doesn't like it that
you make such a large number of connections simultaneously. If the mail
server doesn't protest, probably its systems administrator will.
Moreover there is probably no benefit in having 1000 connections open to
the same mail server because long before there will be another
bottleneck such as your network connection or the CPU load of either
your computer or the mail server, unless you are on a very scalable
infrastructure.
A better solution will be to use a Thread Pool with a limited number of
simultaneous threads (my guess is that 10-20 or so would be good
enough).
And as I said to my students yesterday: You shouldn't program
multithreaded applications unless you have studied this subject
thoroughly. Of course I don't know how this applies to you.

the string goes to the output channel, i.e. outside of the object.
Unfortunately this is one of the leftovers from Python's pre-unicode
heritage. Hopefully in Python3 this will work without problems. Anyway,
in Python 3 the string type is unicode, so at least __repr__ can return
unicode.

No. Where does it set a lock? There is only a short lock period in the queue

It does not depend on the source code's
encoding (supposing that the encoding declaration in the source is
correct). repr returns unicode(self).encode("utf-8"), so it is utf-8
encoded even when the source code had a different encoding. The u"©au"

Here is exactly the problem. Merging the two MRO's as you state would
give C3, C2, C1, object, i.e. C2 before C1.
But your class definition:
class C3(C1, C2):
says that C1 should be before C2. Conflict!!
Change it to class C3(C2, C1):
You see it has nothing to do with the metaclasses. The following code
gives the same error:
class C1(object):

class C2(C1):

CGI scripts return stuff by printing it, or more generally writing to
stdout.
So print message should do. The rest is not a Python question but a
Javascript question.

ewline, or is it
a backslash followed by 'n'? In the first case then every filename is on
a separate line. So then you are mixing two concepts of line.
Anyhow you would make your life easier by getting rid of the \n's.
If all your filenames are numeric with the extension mp3 then the
following gives you a list of the filenames from a line:
In [31]: re.findall('[0-9]+\.mp3', line)
Out[31]: ['100.mp3', '10008.mp3', '10005.mp3', '10001.mp3', '10006.mp3']

ep everything in byte strings your problem may
disappear. In Python 3 you have to do this explicitely as the default is
unicode.

Personally I prefer parentheses: (1).c
For non-SQL you could look into Kyoto Cabinet, which is Berkeley DB-like. Or
ZODB which is a Python Object databes.

Filecmp does a binary compare, not a text compare. So it starts by
comparing the sizes of the files and if they are different the files
must be different. If equal it compares the bytes by reading large
blocks. Comparing text files would be quite different especially when
ignoring line separators. Maybe comparing text files should be added as
a new feature.

were equal, not what the differences would be. In that case difflib is
overkill.
On the other hand `equal' has many meanings. Ignoring line endings is
one option, ignoring trailing whitespace could be another one. Yet

Java, on the other hand does have static typing but does not have
disjoint sums. So they have not much choice but to put null in every
class-based type.

so much different from its inclusion in any other framework. You must
just choose one of the existing editors.
