If all you have is a bunch of functions, just sticking them in a module is fine. The reason you would want to package them up as a class would be if there's some state that needs to be saved. Don't think of a class as a collection of methods, think of it as a hunk of data, and some methods which operate on that data. Looking at it another way, if you write a class and discover that none of the methods ever make any use of self, then what you probably really wanted to do was create a module to hold all those methods as top-level functions. -- http://mail.python.org/mailman/listinfo/python-list

I had a hard time with this at first when I started using Python. I personally come from a background of using Java in an educational environment, so I'm pretty familiar with it. Going from a pure Object-Oriented language, where everything MUST be bundled into a class, and an Object is less of a bit of data and more of a data structure that actually DOES something, was a little difficult. Just repeat this to yourself: Python ISN'T Java. Repeat it until the words start sounding funny to you. Then continue for another 10 minutes. It'll sink in. Anyhow... In Python, classes aren't necessarily treated as things that do stuff (though they can DEFINITELY act in that way!). Python classes are made to hold data. If you have something that you need to save for later, put it in a class and call it a day. If you only have a bunch of functions that are meant to process something, just put them into a module. You'll save yourself some time, you won't have to instantiate a class in order to call the functions, and you'll be happier overall.

Except for those space-separated number pairs, it could be a job for some
well-crafted classes (e.g. `class GEOMETRYCOLLECTION ...`, `class POINT
...`) and eval.
My approach would be to use a loop with regexes to recognize the leading
element and pick out its arguments, then use the string split and strip
methods beyond that point. Like (untested):
recognizer = re.compile (r'(?(POINT|POLYGON|LINESTRING)\s*\(+(.*?)\)+,(.*)')
# regex is not good with nested brackets,
# so kill off outer nested brackets..
s1 = 'GEOMETRYCOLLECTION ('
if data.startswith (s1):
data = data (len (s1):-1)
while data:
match = recognizer.match (data)
if not match:
break # nothing usable in data
## now the matched groups will be:
## 1: the keyword
## 2: the arguments inside the smallest bracketed sequence
## 3: the rest of data
## so use str.split and str.match to pull out the individual arguments,
## and lastly
data = match.group (3)
This is all from memory. I might have got some details wrong in recognizer.

Define the colors 'red', 'green' and 'blue' with ListedColorMap 3. Define the three regions, (-1.0 to -0.50, -0.50 to 0.50, 0.50 to 1.0) with BoundaryNorm([-1,-0.50, 0.50,1], cmap.N). (Why they add the trailing zero in 0.50 and don't change 1 to 1.0; I don't know) 4. Create an array of (x,y) points. 5. Create a collection of tiny segments [(x1,y1),(x2,y2)] and color them with cmap using the boundary rules of norm. lc = LineCollection(segments, cmap=cmap, norm=norm) 6. Use lc.set_array(y) to determine how to color the segments. 7. Plot it.- Hide quoted text - - Show quoted text - Hi Wanderer, Thanks for your help. It works now. Just wanted to know how to go about when I have to do my color mapping not only with respect to range of values on y-axis but also based on some other conditions as well. i.e, say ( range condtion1 condition2 ) where condition1 could be occurance of some event say, a flag1 is set true and condition2 may be another flag2 set to false. Just wanted to use my color mapping not only based on boundaries but also on occurance of other events as well. In this context do i have to modify the source of BoundaryNorm in matplotlib function...?? Can you give me some insights into this. Regards, Ravikanth I don't know if there is another way, but I think changing the lc.set_array input would be the easiest. Each point has an (x,y,z) where z determines the color by what range it is in. You would use your conditions to set points in z to the desired color.- Hide quoted text - - Show quoted text - does (x,y,z) mean adding another dimension 'z' (which is to be used as a condition) to the step 4) as suggested in the steps outlined to me before ? In the matplotlib example they x,y and z. x = np.linspace(0, 3 * np.pi, 500) y = np.sin(x) z = np.cos(0.5 * (x[:-1] + x[1:])) # first derivative Where x and y are the coordinates of the plot and z is

When you're doing primarily numerical data entry, the number pad is typically much faster to touch type with than the main number keys. In the main section, the number keys are too far removed from the home row to be able to type with any speed, and if you reposition your hands directly above them then the Enter, decimal, and Shift keys are no longer easily accessible. Touch typing on the number pad gives you everything you're likely to need in easy reach of your right hand, and if you need something else as well then your left hand is free to hover over it. -- http://mail.python.org/mailman/listinfo/python-list

os.path and Path
In my continuing quest for Python Mastery (and because I felt like it ;)
I decided to code a Path object so I could dispense with all the
os.path.join and os.path.split and os.path.splitext, etc., etc., and so
forth.
While so endeavoring a couple threads came back and had a friendly
little chat in my head:
Thread 1: objects of different types compare unequal
self: nonsense! we have the power to say what happens in __eq__!
Thread 2: objects that __hash__ the same *must* compare __eq__!
self: um, what? ... wait, only immutable objects hash...
Thread 2: you're Path object is immutable...
self: argh!
Here's the rub: I'm on Windows (yes, pity me...) but I prefer the
unices, so I'd like to have / seperate my paths. But I'm on Windows...
So I thought, Hey! I'll just do some conversions in __eq__ and life
will be great!
-- some_path = Path('/source/python/some_project')
-- some_path == '/source/python/some_project'
True
-- some_path == r'\source\python\some_project'
True
-- # if on a Mac
-- some_path == ':source:python:some_project'
True
-- # oh, and because I'm on Windows with case-insensitive file names...
-- some_path == '/source/Python/some_PROJECT'
True
And then, of course, the ghosts of threads past came and visited. For
those that don't know, the __hash__ must be the same if __eq__ is the
same because __hash__ is primarily a shortcut for __eq__ -- this is
important when you have containers that are relying on this behavior,
such as set() and dict().
So, I suppose I shall have to let go of my dreams of
-- Path('/some/path/and/file') == '\\some\\path\\and\\file'
and settle for
-- Path('...') == Path('...')
but I don't have to like it. :(

pycurl and MAX_RECV_SPEED_LARGE
Hello Folks, I have a problem with pycurl. I need to do a download with a lower rate, + or - 1 Kb / 128bytes. I use the MAX_RECV_SPEED_LARGE setting with 128 as value. My problem is: The download take a long time to be finished. File: test.jpg 92 KB, with 128 rate, take 2.38 Minutes. The strange behavior is that: The connection keep ESTABLISHED only 1/5 from all time ( 2.38 minutes ) Analyzing with wireshark, I see that: After pass 1/5 of all time, do not change packages anymore until reach 2.38 minutes, and client send a RST ACK.

Hi Geremy:
I just looked at the docs there. This is a new module (to me), and
I am unsure of the implementation or whether this is what I should
use.
I tried the following :
try :
self.__rdb.execute(S)
except warnings.catch_warnings:
std.mrk('',0,mysql.py:196) ## DEBUG call
## and it does not look like my code modification
## is catching the warning.
Thanks for introducing me to this new module, but I'm not
sure if it is what I should be using.
BTW: End of day in this part of the world. I look forward to any other comments
on this subject tomorrow.

[issue12339] logging.Formatter.format() assumes exception to support str() method which is not true for many libraries.
New submission from Piotr Czachur zim...@gmail.com:
If I want my application to be bullet-proof against external libraries that can
(and often do) raise Exception(u'nonascii'), I cannot use python's
logger.exception() directly, as it will end up with UnicodeDecodeError.
The reason is hidden in Formatter.format() which does:
s = self._fmt % record.__dict__
One can use his own formatter that can handle UnicodeDecodeError, but many
users are quite unaware of such issue and it would be great if Python can
handle it by itself.
Here is a simple case.
e = Exception(u'ą')
logging.basicConfig()
logging.getLogger('general').exception(u'ą')
ą
None
logging.getLogger('general').exception(e)

Vinay Sajip vinay_sa...@yahoo.co.uk added the comment:
This is happening because if you pass an object instead of a string as the
first argument in a logging call, it's treated as a message object whose
__str__() will be called to get the actual message when it's needed, as
documented here:
http://docs.python.org/howto/logging.html#arbitrary-object-messages
If, instead, you do it like this:
# coding: utf-8
import logging
logging.basicConfig()
try:
raise Exception(u'ą')
except Exception:
logging.getLogger('general').exception(u'An error occurred')
you get

[issue1711800] SequenceMatcher bug with insert/delete block after replace
Terry J. Reedy tjre...@udel.edu added the comment: I believe this issue should be closed and have set it to pending. The original report of a 'bug' and the two 'testcases' were and are invalid as they are based on an incorrect understanding of SequenceMatcher. It is not a diff program and in particular not a line diff program but the function used internally by such. It works on sequences of characters, lines, numbers, or anything else. Given the character strings 'abc' and 'abcd\def' it correctly reports that the second is a copy of 3 chars from the first plus insertion of 5 more. Gabriel correctly suggested the above in suggesting that if one wants to compare sequences of text lines, one might use Differ. One could also use SequenceMatcher directly, but this loses the diff-like formatting and report of within-line differences. I think this issue should have been closed then. I do not know what functionality Andrew thinks Christian was talking about. Using Differ with a = ['abc\n'] b = ['abcd\n', 'def\n'] for line in difflib.Differ().compare(a,b): print(line, end='') # prints - abc + abcd ?+ + def One line is replaced with two, with the extra info that the first new line is the old line with an extra char. I do not believe that 'any diffing program' will report the latter. The '?' lines are easily filtered out if not wanted. The patch by Peter has no motivation that I can see other than the idea that replacing a subsequence with one of a different length is somehow bad. Tim Peters did not think so and neither do I -- or Guido. Unequal replacement is built into the syntax of Python: s = [1,2,3] s[1:2] = [4,5,6] s [1, 4, 5, 6, 3] I would not be surprised it the proposed change broke some existing application or degraded performance a bit. -- assignee: tim_one - resolution: - invalid status: open - pending ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1711800 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
