Re: Enumerating formatting strings

I was messing about with formatting and realized that the right kind of
object could quite easily tell me exactly what accesses are made to the
mapping in a string % mapping operation. This is a fairly well-known
technique, modified to tell me what keys would need to be present in any
mapping used with the format.
snip code
I've been wondering whether it's possible to perform a similar analysis
on non-mapping-type format strings, so as to know how long a tuple to
provide, or whether I'd be forced to lexical analysis of the form string.
When I was playing with formatstring % mapping I thought it could
be useful if you could get the full format specifier info an do your own
complete formatting, even for invented format specifiers. This could be
done without breaking backwards compatibility if str.__mod__ looked for
a __format__ method on the other-wise-mapping-or-tuple-object. If found,
it would call the method, which would expect
def __format__(self,
ix,# index from 0 counting every %... format
name, # from %(name) or ''
width, # from %width.prec
prec, # ditto
fc,# the format character F in %(x)F
all# just a copy of whatever is between % and including F
): ...
This would obviously let you handle non-mapping as you want, and more.
The most popular use would probably be intercepting width in %(name)widths
and doing custom formatting (e.g. centering in available space) for the object
and returning the right size string.
Since ix is an integer and doesn't help find the right object without the normal
tuple, you could give your formatting object's __init__ method keyword arguments
to specify arguments for anonymous slots in the format string, conventionally
naming them a0, a1, a2 etc. Then later when you get an ix with no name, you
could
write self.kw.get('%as'%ix) to get the value, as in use like
'%(name)s %s' % Formatter(a1=thevalue) # Formatter as base class knows how
to do name lookup
Or is this just idearrhea?

['more data', 'even more data']
This has the same issues as with opening and closing files: losing the
'dump', having to always use try/finally if needed, accidentally
re-binding 'p', significantly more lines. Moreover, class 'Pickled' won't
be as readable as the 'pickled_file' function above since 'load' and
'dump' are separate methods that share data through 'self'.
A few more lines to create the class, but it encapsulates the data
object better. It is also reusable and extendable.
This class isn't reusable in the case that one wants to pickle something
other than an array. Every type of object that one would wish to pickle
would require its own class.
...Or in a function, or the 3 to 6 lines of pickle code someplace.
Many programs would load data when they start, and then save it when
the user requests it to be saved. So there is no one method fits all
situations. Your thunk example does handle some things better.
Here's yet another way to do it, but it has some limitations as well.
import pickle
def pickle_it(filename, obj, commands):
try:
f = open(filename, 'r')
obj = pickle.load(f)
f.close()
except IOError:
pass
for i in commands:
i[0](i[1])
f = open(filename, 'w')
pickle.dump(obj, f)
f.close()
file = 'filename'
L = []
opps = [ (L.append,'more data'),
(L.append,'even more data') ]
pickle_it(file, L, opps)
Also, this implementation behaves differently because the object is
re-pickled after every modification. This could be a problem when writing
over a network, or to a shared resource.
-Brian
In some cases writing to the file after ever modification would be
desired. A way around that would be to use a buffer of some sort. But
then again, that adds another level of complexity and you would have
to insure it's flushed at some point which get's back to the issue of
not closing a file.
Thanks for explaining how thunks works. I'm still undecided on
whether it should be built in feature or not.
I would rather have a way to store a block of code and pass it to a
function, then execute it at the desired time. That would solve both
the issue where you would use a thunk, and replace lambdas as well.
But I understand there's a lot of resistance to that because of the
potential abuse.

After all I start backtracking: the purpose of defining suites is still prevention of namespaces pollution with helper-functions not a sake of it's own and not inventing of a suite-based programming style for everything. The examples You presented have become almost pathological examples of what should be prevented and where syntax cannot be rigid enough. So there are following requierements about we seem to agree: - define suites on a functions-call scope in order to define helper functions that would otherwise pollute external namespaces - mark the func-call-scope by some keyword either with or where because it has to be separated from the calling environment both for consistency and user friendlyness - Simple matching rules for both keyword-parameters and argument-tuples. Make explicit which kind of inference rule is selected.

Question about python 2.4 documentation
Hello all. I have a small question concerning the functions open(...) and file(...) with python 2.4 In the online version of the documentation in the build-in functions (section 2.1 http://docs.python.org/lib/built-in-funcs.html) here is an quote of the file(...) doc : The file() constructor is new in Python 2.2 and is an alias for open(). Both spellings are equivalent. The intent is for open() to continue to be preferred for use as a factory function which returns a new file object. The spelling, file is more suited to type testing (for example, writing isinstance(f, file)). In my installed python 2.4 documentation the correspondig quote : The file() constructor is new in Python 2.2. The previous spelling, open(), is retained for compatibility, and is an alias for file(). If I understand well, in my version it is recommended to use file() function instead of open(), and in the online version it is the opposite. what is the favorite function you recommend me to use ?

Re: pre-PEP: Suite-Based Keywords - syntax proposal

foo = f1; bar=f2; x=k1; y=k2
I think we are diverging again. You are right with Your objection about
my claim of generality but I'm completely against the latter statement
not only because
foo(x) where:
foo = f1
is not much better than
foo(x) where:
def foo():
# do some stuff
which should clearly raise an exception and be abandoned.
Why do you say that? foo(x) is just a call of whatever foo is bound to.
The where: suite supplies a transient namespace where foo happens to
be defined in the conventional way. This allows definition and call of
foo without binding it in the caller's local namespace, much like
(lambda(): do_some_stuff)()
IMO that's a perfectly valid use. You don't have to worry that your
def foo():... will clobber some other foo.
After all I start backtracking: the purpose of defining suites is still
prevention of namespaces pollution with helper-functions not a sake of
it's own and not inventing of a suite-based programming style for
everything. The examples You presented have become almost pathological
examples of what should be prevented and where syntax cannot be rigid
enough.
You don't have to write what you consider to be pathological, but
this becomes sort of a free speech issue. I.e., don't impose a style-censoring
spell-checker on me please ;-)
So there are following requierements about we seem to agree:
- define suites on a functions-call scope in order to define helper
functions
that would otherwise pollute external namespaces
Why just function call? You realize that a function call is just the
effect of (arglist) tacked on the tail of an expression that is not
necessarily just a name. E.g., notice the possibilities the parser goes
through before finding that foo() is a simple name expression with a () trailer:
[ 1:18] C:\pywk\parse\astpy24 debg.py -full foo()
'file_input'
'stmt'
'simple_stmt'
'small_stmt'
'expr_stmt'
'testlist'
'test'
'and_test'
'not_test'
'comparison'
'expr'
'xor_expr'
'and_expr'
'shift_expr'
'arith_expr'
'term'
'factor'
'power'
'atom'
NAME 'foo'
'trailer'
LPAR '('
RPAR ')'
NEWLINE ''
ENDMARKER ''
What about instance.method(args) as a call? Should you not be
able write
instance.method(*args) where:
args = []
# append various values to args here,
# in single statements and/or using looping etc.
to specify complex args in a where? That looks like
[ 2:18] C:\pywk\parse\astpy24 debg.py -full instance.method(*args)

Re: ANN: Veusz 0.5 - a scientific plotting package

I've been accused of the same, on more than one occasion :-) But I'm also aware of the problem that this creates -- the tyranny of choice. python is so fun to code in that many developers are looking for a reason to find an existant package inadequate so they have an excuse to write their own replacement. Hence we have a proliferation of web-app frameworks, plotting packages, array objects and so on. There is a lot of duplicated effort in many arenas and it would be nice to collaborate more. True. It's sad that it's just more fun to go off and write something yourself, but it is fun :-) I'm afraid I'm not very good with using other people's codebases. I read over your scipy list of problems that you found in matplotlib -- some were helpful and some, as you note, have been long fixed. One critique you might flesh out for me is the notion that matplotlib's object model is baroque -- most of the developers feel the object model is fairly solid. You weren't by chance, trying to use the procedural pylab (aka matlab) interface, were you, since pylab itself is just a wrapper of the OO matplotlib API? One area in the object model that we plan to change is to make high level plot objects (scatter, error, histogram) etc, proper objects, ala gnuplot. Right now they are methods that generate primitive objects (lines, rectangles, text, etc). I thought I was using the object interface. It seemed strange to me that methods of the axes were used to plot data, draw legends, and so on... It seemed to make much more sense to have these as objects themselves. The main problem is that there's no object you can alter to change their appearance. I quite like the object system I've developed, where the external interface is completely based on building the object hierarchy and setting properties of the objects (plus there is a functional interface, but this is only used rarely for active operations, like fitting data). I wanted an interface where I could twiddle a bit, and change the axis from log to linear, or vertical to horizontal... I wasn't sure which variables in the matplotlib source I could touch and get away with in future releases :-) Another area you identify as a problem with matplotlib is the need to regenerate the entire graph when one property is changed. This is true in one way and false in another. matplotlib does have a proper object model -- eg, you can selectively change the facecolor of a marker w/o regenerating the graph scene. But the *drawing* hierarchy (as opposed to the object hierarchy) needs some work . Once you have changed a property, the entire graph is redrawn. This is a known limitation and will change in the not-too-distant-future. One advantage of working in mainstream in open source software is the network effect. With 10 some-odd developers including institutions such as the U of C, STScI, JPL and NOAA, bugs and limitations of matplotlib tend to be fixed within minutes, days, weeks or months. It looked to me that you could change some properties (like line style) after creating the graph, but other things were hard to change (marker style?). Therefore I deleted the graph and rebuilt it from scratch each time. The way you modify a property is different from how you set it when building a graph, and so it was difficult to create a transparent interface. Your package looks very nice. It specifically addresses two limitations in matplotlib that we would like to address -- a GUI interface for creating figures and a way to save the figure at any point as a high level description (rather than an image). I do wish you had publicly voiced the problems you ran into along the way; I just searched the archives and saw only one post from you on the users list which I answered 28 minutes later with http://sourceforge.net/mailarchive/message.php?msg_id=10124206 after which I never heard from you again. Such response times are fairly typical on the list, but if you don't report the bugs and follow up on the suggested fixes, we can't fix them. Sorry - much of my work was done when I didn't have a very good internet connection, and so it was hard for me to collaborate over bugs. I took the easy option of expanding the small codebase I already have (which I knew pretty well!), over debugging someone else's code. Anyway, nice work on veusz. Are you committed to the GPL license? matplotlib uses a more permissive license (PSF compatible) mainly to encourage contributions from the commercial sector. As you suggest, it is still possible for someone to take the work you've done on the GUI frontend and expose matplotlib as a backend based on your prior experiments.

Re: modules and namespaces
Each module has its own namespace, which is like a dictionary of
objects that the module can see. I use the term dicitionary because
locals() and globals() both return dictionaries -- someone may correct
me on this (or confirm what I say)...
You have local and global variables.
Locals are variables in the scope of a function.
def myfun():
localvar = 1
`globals' are really 'module' global only.
# mymodule
global_var = 3
def myfun()
print global_var
# This is a *gotcha* -- you can't change global variables this way.
# here, a new local variable global_var is initialized.
global_var = 3
def changeglobal():
# you have to use `global' to instruct python to use the `global'
instance of the variable
# instead of creating a new one when you assign to it.
global global_var
global_var = 3
You can only see variables you've created or modules you've imported.
Becase you haven't imported string in m2 or m3, you can't see them.

New to Tkinter...
Good Morning. I am new to Tkinter. I have been testing the installation of Tkinter through the python web site. The first two test steps give no errors, 'import _tkinter' and 'import Tkinter'. However, the third step, 'Tkinter._test', gives the error: function _test at 0xb7ec8df4 Any suggestions? pete -- Peter G.

This works. The only thing you have to do is stuff a floppy into the
drive find out what the fstype is (that's inf[-1] in the code below)
so you can key on it. Try the docs for Mark Hammond's Win32, and
there's always his _Python Programming on Win32_.
import os
import os.path
import win32api
def findCDs():
cdDrives=[]
print Searching for cd drives...
drives=win32api.GetLogicalDriveStrings().split(:)
for i in drives:
dr=i[-1].lower()
if dr.isalpha():
dr+=:\\
inf=None
try:
inf=win32api.GetVolumeInformation(dr)
except:
pass # Removable drive, not ready
if inf!=None:
if inf[-1].lower().endswith(cdfs):
cdDrives.append([dr,inf])
elif inf[-1].lower().endswith(udf):
cdDrives.append([dr,inf])
return cdDrives
inf[0] contains the volume label if there is one and if there's a CD
loaded:
win32api.GetVolumeInformation(c:\\)
('God_C', -798323922, 255, 459007, 'NTFS')
Note that you must use the full drive spec, letter:\\ or
GetVolumeInformation() doesn't always work.
There are probably better ways to do these things, but they do work;
I've been using them constantly the last few days.

Re: Why does python class have not private methods? Will this never changed?
Have I missed something? Doesn't this mangle class methods: class Foo: def __bar(self): print bar Granted, you could probably figure out how the names are being mangled. In the example above __bar is a defacto private method. Griping about it not having `private' in front of it is asinine. If someone intentionally has to call a `private' method, then the design is at fault, not the language. jw On 4/19/05, Peter Hansen [EMAIL PROTECTED] wrote: Roy Smith wrote: Simon Brunning [EMAIL PROTECTED] wrote: On 4/19/05, could ildg [EMAIL PROTECTED] wrote: Private stuff always makes programming much easier.

It's appealing, indeed, trying to create more uniformity between tuple unpacking and argument passing. There are two approaches towards such uniformity, either upgrading tuple unpacking (as the above thread discusses) or downgrading argument passing (as suggested by those who found atrocious the current behaviour). I started recently to study the R system and language, and saw many good ideas in there about argument passing. Translated in Python terms, it would mean that `*varargs' and `**keywords' are not necessary last, that named keywords may be intermixed with positional keywords, that keywords may be abbreviated, and much more hairy, that the default values for keywords are not pre-evaluated at `def' time, and that the computation of actual expressions given as arguments is lazily postponed until their first use within the function. It surely looks all strange at first, but these choices are surprisingly productive in practice, as I merely begin to understand. Curious minds may start at http://cran.r-project.org/doc/manuals/R-lang.html#Arguments and read down.

Re: (Python newbie) Using XP-SP2/MSVC6: No Python24_d.lib, winzip barfs on Python-2.4.1.tar, cannot download bzip2
Okay, let me have another stap at this. As you have probably noticed MSVC6 is no longer actively supported as far as Python 2.4 goes. The official distribution of Python 2.4 for Windows is built using MSVC7.1 (or whatever you wish to call it). We are told that building C extensions with MSVC6 for use in the official Python 2.4 (which uses the MSVCR71) is not safe, and mixing the different runtime libraries that your extension (or my extension) with that which official Python 2.4 uses will/might cause crashes. Google around for details on this. So, what to do? You seem to have four options. 1. Get and use the MSVC7.1 compiler. 2. Get and use the freely distributed MS compiler. 3. Download the Python source[1] and compile it yourself in MSVC6 (there are project files in the source to enable you to do that). Then use your MSVC6 to create the extension. 4. Get and use MinGW and pyMinGW[2] Regards, Khalid [1] Check to see if your archiever tool is working, or get the source from CVS.

In the new (2.4) version of the Tutorial, that statement has been removed. What you're using has been called old-style classes for quite a while now (since 2.0?). Any new Python code should really be using the new-style classes (inherit from object and use things like super. But FWIW, it appears to still work with Python 2.4: #-- snip FILE=Foo.py - class Foo: def foo(self): print foo class Bar(Foo): def foo(self): print bar Foo.foo(self) #--- /snip # Now in the Python interpreter: from Foo import * f = Foo() f.foo() foo b = Bar() b.foo() bar foo So nothing jumps out to me that you did obviously wrong, sorry.

Re: Strings and Lists
Thank you all very much for your responses. It's especially reassuring to hear about other Python GA's as I have had some scepticism about Python's speed (or lack of it) being too big a problem for such an application. With regard to using numeric, arrays or integer lists -- I didn't mention that these strings can also contain wild cards (so I suppose it's not really binary -- sorry). This is traditionally done using a '#' symbol, but I was imagining using a value of None in a boolean list to represent this. Also there is currently a fair bit of research going into other representations (floating-point values, paired values etc) so I was hoping to be able to keep my framework extensible for the future. Many thanks again for your help. I will ``take the plunge'' and give the boolean list a go I think! -- http://mail.python.org/mailman/listinfo/python-list

The good news is that you can know for sure that you are going to Heaven which is described in the Holy Bible as a beautiful place with no death, sorrow, sickness or pain. God tells us in the Holy Bible how simple it is to be saved so that we can live forever with Him in Heaven. For if you confess with your mouth Jesus is Lord and believe in your heart that God raised Him from the dead, you WILL BE SAVED. (Romans 10:9) Over 2000 years ago God came from Heaven to earth in the person of Jesus Christ to shed His blood and die on a cross to pay our sin debt in full. Jesus Christ was born in Israel supernaturally to a virgin Jewish woman named Mary and lived a sinless life for thirty-three years. At the age of thirty-three Jesus was scourged and had a crown of thorns pressed onto His head then Jesus was crucified. Three days after Jesus died on a cross and was placed in a grave Jesus rose from the dead as Jesus said would happen before Jesus died. If someone tells you that they are going to die and in three days come back to life again and it happens then this person must be the real deal. Jesus Christ is the only person that ever lived a perfect sinless life. This is why Jesus is able to cover our sins(misdeeds) with His own blood because Jesus is sinless. The Holy Bible says, In Him(Jesus) we have redemption through His blood, the forgiveness of sins... (Ephesians 1:7) If you would like God to forgive you of your past, present and future sins just ask Jesus Christ to be your Lord and Saviour. It doesn't matter how old you are or how many bad things that you have done in your life including lying and stealing all the way up to murder. Just pray the prayer below with your mouth and mean it from your heart and God will hear you and save you. Dear Jesus Christ, I want to be saved so that I can have a home in Heaven with You when I die. I agree with You that I am a sinner. I believe that You love me and want to save me. I believe that You bled and died on the cross to pay the penalty for my sins and that You rose from the dead. Please forgive my sins and come into my heart and be my Lord and Saviour. Thanks Lord Jesus Christ for forgiving me and saving me through Your merciful grace. Amen. Welcome to the family of God if you just allowed God to save you. Now you are a real Christian and you can know for sure that you will live in Heaven forever when this life comes to an end. As a child of God we are to avoid sin(wrongdoing), but if you do sin the Holy Bible says, My dear children, I write this to you so that you will not sin. But if anybody does sin, we have one who speaks to the Father in our defense Jesus Christ, the Righteous One. Those of you that have not yet decided to place your trust in the Lord Jesus Christ may never get another chance to do so because you do not know when you will die. Jesus said I am the way, the truth and the life: no one can come to the Father(God)(in Heaven), but by me. (John 14:6) This means that if you die without trusting in Jesus Christ as your Lord and Saviour you will be forever separated from the love of God in a place called Hell. The Holy Bible descibes Hell as a place of eternal torment, suffering, pain and agony for all those who have rejected Jesus Christ. The good news is that you can avoid Hell by allowing Jesus Christ to save you today. Only then will you have true peace in your life knowing that no matter what happens you are on your way to Heaven. Praise the Lord! Servant of the Lord Jesus Christ Ronald L. Grossi *Show this to your family and friends so they can know that they have a choice where they will spend eternity. Thanks!
