This uses around 100MB of memory as expected and 'del l' will clear that.

This is using 165MB of memory. I really don't understand where the

If I reduce the string size, it remains high till it reaches around
1000. In that case it is back to 100MB usage.

So on Python 2.6.6 + Ubuntu 10.10, the second is actually a little smaller
than the first.
Some issues you might ponder:
1) Does FreeBSD's malloc/free know how to free unused memory pages in the
middle of the heap (using mmap games), or does it only sbrk() down when the
end of the heap becomes unused, or does it never sbrk() back down at all?
I've heard various *ix's fall into one of these 3 groups in releasing unused
pages.
2) It mijght be just an issue of how frequently the interpreter garbage
collects; you could try adjusting this; check out the gc module. Note that
it's often faster not to collect at every conceivable opportunity, but this
tends to add up the bytes pretty quickly in some scripts - for a while,
until the next collection. So your memory use pattern will often end up
looking like a bit of a sawtooth function.
3) If you need strict memory use guarantees, you might be better off with a
language that's closer to the metal, like C - something that isn't garbage
collected is one parameter to consider. If you already have something in
CPython, then Cython might help; Cython allows you to use C datastructures
from a dialect of Python.

import socket
# the public network interface
HOST = socket.gethostbyname(socket.gethostname())
# create a raw socket and bind it to the public interface
s = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_IP)
s.bind((HOST, 0))
# Include IP headers
s.setsockopt(socket.IPPROTO_IP, socket.IP_HDRINCL, 1)
# receive all packages
s.ioctl(socket.SIO_RCVALL, socket.RCVALL_ON)
# receive a package
while 1 :
print(s.recvfrom(65565))

I hope put value1 to b.variable1, value2 to b.variable2 and value3 to
b.variable3. it does not work. How can I do it?
By the way, I know dictionary can bind two variable together, like a 2-
dimension array. but, if I need group 3 or more variables together,
(each group has 3 or more variables)like a 3-dimension(or higher)
array, Is there an easy way besides class?

b.key gets the key attribute of b, not the attribute that has the
same name as the variable called key. Otherwise, you'd have to
reference it as b.key normally. If you want to dynamically set the
variable, you'll have to use the setattr function
setattr(b, key, c[key])

A dictionary does not bind two variables together. A dictionary is a
hash map- it maps keys to values. Each key will map to exactly one
value. If you want to store a list of associated values, use a tuple.
A tuple is an immutable collection of objects (the tuple itself is
immutable, not necessarily the objects in it). It can be indexed just
like a list.
l = [(0,0), (0,1,2,3,4,5,6,7), (0,1,'foo', 5 ,6)]
l[0]
(0, 0)
l[2]
(0, 1, 'foo', 5, 6)

Just change the shebang to point to your package's virtual Python installation. That obviously won't work for Windows, which uses system-wide file-type associations.

Re: enhanced map function
Steven, Thanks for the info of itertools. It is a great start for me. Overall, I agree with you that it is really the user data needs to be sorted out. However, novice users may need help on certain patterns such as a=[1,[2,3],4], b=[5,[6,7,8],9,10]. We could just draw our line saying that similarly nested inputs could be adjusted even though the members aren't exactly on one-to-one mapping and we won't getting any deeper for complicated cases such as a = [1, 2, [3, 4]]; b = [1, [2, [3,4]], [4,5], 6]. enhanced_map([1, [2,3, [4,5], 6], 7], [8, [7,6, [5,4], 3], 2]) should be the same as map([1, 2, 3, 4, 5, 6, 7], [8, 7, 6, 5, 4, 3, 2]) I don't expect the drop. The original nested structure is very important. What do you expect to happen if the sub-sequences don't match up exactly? E.g. a = [1, 2, [3, 4]]; b = [1, [2, 3], 4] What do you expect to happen if the shorter list is empty? E.g. a = [1, 2, [3, 4], 5]; b = [1, 2, [], 3] There are modes called shortest and longest (and AllCombination/Cross which is more complex). For case a = [1, 2, [3, 4],4]; b = [1, [2, 3], 4,5] shortest: a will be adjusted to [1, [3, 4],4] b will be adjusted to [1, [2, 3],4] longest: a will be adjusted to [1, 2,[3, 4],4,4] b will be adjusted to [1, 1,[2, 3],4,5] As I said previously, the enhance_map function will only handle limited unmatch cases and the line will need to be drawn carefully.

I have found this approach problematic if you have packages separately developed and maintained in different directory trees, resulting in more than one PYTHONPATH entry with the same root metapackage name. What happens is that only the first entry in the PYTHONPATH containing the metapackage name is looked in for package/module resolution.

Re: value of pi and 22/7
(pulls out doctorate in Math.) Take a circle and measure its diameter, then circumference (coffee cans and string are helpful). Then pi = Circumference/diameter approximating that is hard. It turns out that even though it *looks* like a nice fraction, the value that results is not (fractions of integers have the charming property that they always repeat, for instance 22/7 = 3.142857 142857 142857 142857 142857... Pi does not. Again this was a very hard question only answered in the 18th century by Lambert, I do believe.) It is the simple fractional look about pi vs. how hard it is to compute that drives most of the confusion about pi. The digits of pi are in effectively random order (each digit occur roughly 10% of the time), and to compute the nth one you need all the digits before it. Once upon a time (and maybe still) sending back and forth long strings of the digits of pi was a great way to test communications, since each side could look up the result in a table and tell if there were systematic errors. There are fun math questions, for instance, is there a run of a million 1's someplace in the decimal expansion of pi? Maybe so, but we just don't know, since we've only computed the first trillion or so digits. Computing pi also requires a lot of logistical organization too and cranking out the first several hundred million digits is still often used to test systems. FWIW my favorite approximation is 355/113. I can always seem to remember that one the best...

Note that Liouville's constant, the number sum_{j = 1}^\infty 10^{-j!}
is easily seen to be irrational (and is also transcendental), but no
string of a million 1's, or any digit other than 0 and 1, appears in its
decimal expansion. The relevant concept is that of a normal number,
which is one whose digits look random:
http://en.wikipedia.org/wiki/Normal_number
Pi has not been proved to be normal but it is suspected on purely
statistical grounds that it is, since almost all real numbers are normal
(in the sense that the set of non-normal real numbers has Lebesgue
measure 0).

Then use style map and style default to control the border appearance:

b.key gets the key attribute of b, not the attribute that has the

A dictionary does not bind two variables together. A dictionary is a

A tuple is an immutable collection of objects (the tuple itself is

Txs for your help I actually have another really weird behavior in this program, but haven't figured out yet what causes it so it is hard to tell if it's an error on my part or another system bug. I'll post it if I can isolate a system error. FWIW, what I am doing is using Configparser to assemble a bunch of classes together to provide a reporting/diffing engine for database comparisons. The object compositions are all defined in an .ini file. I've found Python + ini files are a great match for creating truly flexible programs. SQL queries, template strings and regular expression patterns can be stored in the ini file and are easy to modify without touching the core python code. Pass a different ini file = different behavior. Xml is overkill for this and plays really badly with relational , operators. This is the next step for me, defining mostly separate classes and assembling and initializing them based on ini file configuration info. -- http://mail.python.org/mailman/listinfo/python-list

Can you point at a reference for the latter? I have been trying to convince my company that PG is better than MySQL. -- Well, my $.02 worth is that, about 3 yrs ago, on 5.0x-5.1x, I was truly appalled by the sheer level of stupidity displayed by MySQL's handling of a moderately complex UPDATE SQL query with a correlated subquery. (Let's say this was a 7 out of 10 complexity, with your standard selects being 1-3 max and a nightmare update query with all sorts of correlated subqueries would be a 9. I am first of all a database programmer, so queries are my world). Not only did MySQL mangle the query because it didn't understand what I was asking, it thrashed the data during the update and committed it. And, when I reviewed the query once again, I found I had mismatched parentheses, so it wasn't even syntaxically correct. Truly scary. DB2 + SQLBase punted for years on correlated subqueries Ex: update ORDERS where x=y and exists (select 1 from ORDERS where some condition). The DB2 engine doesn't know how to handle them, so it tells you to get lost. MySQL is not smart enough to recognize it's over its head and instead makes a best effort. To me it looks like a database that will get you 80% there and steadfastly refuse the last 20%, assuming you need really clever queries.

[issue11055] OS X IDLE 3.2 Save As menu accelerator opens two Save windows
Ned Deily n...@acm.org added the comment:
The actual unwanted event is being generated as a result of the menu add
command accelerator. You can see that by playing with Wish.
set w .menu
catch {destroy $w}
toplevel $w
wm title $w Menu Shift
menu $w.menu -tearoff 0
set m $w.menu.basic
$w.menu add cascade -label Basic -menu $m -underline 0
menu $m -tearoff 0
$m add command -label Test \
-command puts command -accelerator Command-Shift-A
bind $w Command-Shift-A puts bind
$w configure -menu $w.menu
It appears that there is a bug in the Cocoa Tk right now where accelerators
with Shift (at least) in them are not being properly ignored by Tk. In the
Carbon Tk and the X11 Tk, I believe the only effect of the accelerator
definitions on the add command is to be used to create the shortcut
characters displayed in the menu entry. However, apparently a side effect of
using the Cocoa APIs is that the menu definitions now cause notifications back
into Tk which are not supposed to be translated into Tcl/Tk events back to the
app. For some reason, the shift ones are not being ignored.
https://github.com/das/tcltk/blob/master/tk/macosx/tkMacOSXMenu.c
Also, it seems that with all three of the Tk implementations (Carbon, X11, and
Cocoa), using a capital letter for the menu accelerator implies Shift.

Mark Dickinson dicki...@gmail.com added the comment: [Robert] I have to disagree. It seems entirely reasonable to expect that unpack should return the same value passed to pack. Robert: notice that a *Python* float (a *64-bit* C double internally) is here being stored as a *32-bit* float, losing precision. So no, it's not at all reasonable to expect that unpack should return the same value passed to pack---it's mathematically impossible for it to do so. There are (around) 2**64 distinct Python floats, and only 2**32 ways to pack them using 'f'. When packing / unpacking using 'd', it *is* reasonable to expect the value to be recovered exactly, and as far as I know that's always what happens (barring peculiarities like NaN payloads not being reproduced exactly). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4114 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from Steffen Daode Nurpmeso sdao...@googlemail.com: My minimal failing test case dragged yet another EMAIL error to the light!!!
