Python isn't perfect, but I do believe that is as good as the best of the major "standard" systems out there. You will have *far* greater chances of introducing errors yourself by coding in c, than you will encounter in Python.

Windows installer, different versions of Python on Windows
I would like to install several copies of Python 2.4.2 on my machine, but it doesn't seem to be possible.

You should probably pass a sequence to the method instead. You can do it
the other way, but it's poor coding style in most cases.

Setting the default value to a value that cannot exist as an argument is
the normal way. Eg. None.
def fn(vals, cmp=None)

def fn(*values, cmp=None):
if cmp is None:
raise TypeError, "'%s' is an invalid keyword argument for this

If you insist on doing it the other way:
FN_LEGAL_ARGS = set( ('cmp',) )
def fn(*values, **options):
for key in options.keys():
if not key in FN_LEGAL_ARGS:
raise TypeError, "'%s' is an invalid keyword argument for
this function" % key

Precisely. Sometimes you need different interfaces for a method. In that case it is fine. But if you are just doing it instead of passing sequences, you are just (ab)using the * and ** operators. The method definition, like any python code, is made for humans not machines. The more obvious you can make the function definition, the happier anyone will be. -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science -- http://mail.python.org/mailman/listinfo/python-list

You should make a wrapper around the library that handles the midi
events in a data structure.
When your musical structure is then is complete, you use the midi
library to write it to disk.
I have attached a simple example here.

Because it tries to print it out to your console and fail. While writing

Yes. This can be especially nice when you need to use restricted charsets.
I needed to use unicode objects as Zope ids. But Zope only accepts a
subset of ascii as ids.
So I used:
hex_id = u'INBOX'.encode('utf-8').encode('hex')

And I can get the unicode representation back with:
unicode_id = id.decode('hex').decode('utf-8')

Tn that case id.decode('hex') doesn't return a unicode, but a utf-8

oddities in the datetime module
# -*- coding: latin-1 -*- """ I am currently using the datetime package, but I find that the design is oddly asymmetric. I would like to know why. Or perhaps I have misunderstood how it should be used? I can make a datetime easily enough >>> datetime(2005, 1, 1) datetime.datetime(2005, 1, 1, 0, 0) What I find odd is that I cannot make a new datetime object from the timetuple() like this: >>> d1 = datetime(2005, 1, 1, 12, 13, 10) >>> d2 = datetime(*d1.timetuple()) Traceback (most recent call last): ... TypeError: function takes at most 8 arguments (9 given) >>> d1.timetuple() (2005, 1, 1, 12, 13, 10, 5, 1, -1) Because if I subclass datetime, I often need to convert between my subclass and the built in datetime module. But there is no direct way to do it. Instead I have to do it in a somewhat more clunky way: >>> datetime(* (d1.timetuple()[:6] + (0, d1.tzinfo))) datetime.datetime(2005, 1, 1, 12, 13, 10) if I want to convert a date to a datetime it is easy, even though I still have to truncate the timetuple. >>> d = date(2005, 1, 1) >>> datetime(*d.timetuple()[:6]) datetime.datetime(2005, 1, 1, 0, 0) The other way around is also easy. >>> dt = datetime(2005, 1, 1, 12, 0, 0) >>> date(*dt.timetuple()[:3]) datetime.date(2005, 1, 1) But it's a clunky design that I have to do it that way.

Re: oddities in the datetime module
Serge Orlov wrote: Max M wrote: Yes, you did. datetime.timetuple is those who want *time module* format, you should use datetime.data, datetime.time, datetime.year and so on... As they say, if the only tool you have is timetuple, everything looks like tuple Try this: dt = datetime(2005, 1, 1, 12, 0, 0) dt.date() datetime.date(2005, 1, 1) This doesn't solve it. I don't think you understand my issue. First of, it should be possible to easily convert between the datetime objects. And eg. the date object doesn't have a datetime() method. Which it could easily have. Neither does time. They could have. But I don't think that is the way to solve it. It is a problem if you make a subclass of datetime. Often you will ned to make datetime arithmetics with the new class. Like: datetime_subclass_1 + datetime_subclass_2 The result of that is a plain datetime In that case you will rather want your own subclass returned. But subclasses of datetime returns datetime objects. Not the subclass. So to do an add of your own objects you must convert the output to your own class "manually" class my_datetime(datetime): def __add__(self, other): result = datetime.__add__(self, other) return my_datetime(result.timetuple()[:6]) datetime(), time() etc. methods will not help with this. -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science -- http://mail.python.org/mailman/listinfo/python-list
[ANN] iCalendar package 0.9
I have written a package that can parse and generate files according to RFC 2445 (iCalender). That should be any file ending with .ics :-) It is not quite polished yet, but fully functional, and choke full of doctest. It does support the full spec and all datatypes and parameter values. The Api is pretty stable, and will probably not change much. I would like anybody interrested to give it a test drive before I finish it off and make it a 1.0. http://www.mxm.dk/products/public/ical/ Any feedback would be welcome. -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science -- http://mail.python.org/mailman/listinfo/python-list

How well do you cope with the crud that real programs generate? Does it work
with the different dialects uses out there? Can it at least identify them?
It depends on how badly the data is screwed up. But generally it should
be able to work on incorrect implementations.
It doesn't care of the spelling of property and parameter names. Though
type conversions will need to be done slightly more manual.
If something like 'dtstart' is misspelled it will not return a datetime
>>> cal.decoded('datestart')
But if you know that it is misspelled you can get it, and convert it
manually like:
>>> from PropertyValues import vDDDType
>>> vDDDType.from_ical(cal['datestart'])

But it is a lot smarter, because the files and directories are actually objects with different attributes and parameters. The methods on these objects can then be called eg. from a web browser with different parameters.

This will mean string literals in your source code will be encoded as
UTF8 - if you handle them with normal string operations you might get
funny results.
It means that you don't have to explicitely set the encoding on strings.
If your coding isn't set you must write:
ust = 'æøå'.decode('utf-8')
If it is set, you can just write:
ust = u'æøå'
And this string will automatically be utf-8 encoded:
st = 'æøå'
So you should be able to convert it to unicode without giving an encoding:
ust = unicode(st)

A recipe would be excellent. Unfortunately yours is no right. It should
have looke like:
>>> imapUTF7Encode(u"\u00ff")
'&AP8-'
I believe you missed the 'special' in "The special UTF-7 codec for IMAP?"
Imap folders use a non-standard version of utf-7, where some characters
are different.
I found som messages from 2001 on the net between a few Python unicode
developers, where they discuss implementing it. But I cannot find an
implementation anywhere.
I found a perl module that converts to/from the codec, but as usual that
is regex hell. Well ok its not that difficult, but I still need to think
to hard to parse Perl regex'

Re: Why are tuples immutable?
Antoon Pardon wrote: Well IMO there are two sides in this argument. The first is whether or not python allows mutable keys. The second is whether or not limiting keys to immutables in dictionaries provides a performance gain. The problem is that you don't understand what dicts are typically used for. Because of the nonliniarity in dict lookups, dicts are used for optimisation. I actually think it's the most important tool for optimising Python code. If dicts allowed mutable keys, a dict would need to run code that corresponds to:: def has_key(key): for key in self.keys(): if a_key == key: return True return False Using immutable keys, a code can be generated for the key, that can be efficiently stored in something like a binary tree. This makes lookup *very much* faster, and is the speed concern that Python programmers care about. Not the time taken to convert a list into a tuple. -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science -- http://mail.python.org/mailman/listinfo/python-list

Maybe you should shange your tactics. What about just fetching the settings from the client? That way the send function will be the same, and you can control it. But the server settings could be fetched from the different clients. It is probably much simpler to find those than it is to use them as the sender.

It simply kept on to it, so it could reuse it again later. From 2.5 onwards it should release most of the unused memory. However it doesn't use less memory. The peak memory usage should be the same as before. So for one-off programs that starts up and runs once, there should not be much gain. -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science -- http://mail.python.org/mailman/listinfo/python-list

Irony does mean that one says the opposite of what one really means. If you do it for humor its irony, if you do it for mocking it is sarcasm. So now I see... americans really *do* understand irony. -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science -- http://mail.python.org/mailman/listinfo/python-list

As a Dane that is a Chronic Ironic, I beg to differ. In Denmark at least there is a lot of difference between irony and sarcasm. Irony is the main form of humor here, and danes takes to it easily. People being sarcastic we don't much like. But I guess that it can be hard to se the difference for someone not used to irony. I believe the reason that irony works here is that we have such a homogenous society. Somewhere like the US where the cultural differences are larger, it is probably a lot harder for irony to be taken as such and not as sarcasm. -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science -- http://mail.python.org/mailman/listinfo/python-list

No. You are probably running your script in an ide that keeps an old variable hanging around.

I wrote "different in use". Which is not the same as saying it has not changed. The general feel of coding in Python is exactly the same to me. I believe that most of those changes you mention are rarely used by most programmers. -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science Phone: +45 66 11 84 94 Mobile: +45 29 93 42 96 -- http://mail.python.org/mailman/listinfo/python-list

Ideas are a dime a dozen. Implementation is the hard part. If you want something done, you will have to do it yourself. I am not trying to be negative, but I will bet you that every competent programmer on the list has 1+ project that she would love to do, if she just had the time. -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science Phone: +45 66 11 84 94 Mobile: +45 29 93 42 96 -- http://mail.python.org/mailman/listinfo/python-list

Do yourself a favor and use the email module to construct your messages
with. Constructing messages by hand can lead you into so many traps.
Especially if you are using international characters in you messages.

What is the problem with encoding the message as utf-8 before setting
the payload? That has always worked for me.
pl = u'Some text with chars that need encoding:\xa3'.encode('utf-8')
msg.set_payload(pl ,charset)
From the docs:
"""
The payload is either a string in the case of simple message objects or
a list of Message objects for MIME container documents (e.g. multipart/*
and message/rfc822)
"""
Message objects are always encoded strings. I don't remember seeing that
it should be possible to use a unicode string as a message.
The charset passed in set_payload(pl ,charset) is the charset the the
string *is* encoded in. Not the charset it *should* be encoded in.
