Re: GCD in Fractions
blindanagram wrote: Seccondly (as others here have pointed out), the mathematical properties of the greatest common divisor are well defined for both positive and negative integers. You keep saying that, but it simply is not true. Different people use different definitions. Some refuse to allow negative arguments at all. Some insist that the GCD must be positive. Others allow it to be negative. GCD is well-defined for **positive integers only**. Mathworld emphasises positive integers in their definition, repeating the phrase THREE times in the first paragraph: The greatest common divisor, sometimes also called the highest common divisor (Hardy and Wright 1979, p. 20), of two positive integers a and b is the largest divisor common to a and b. For example, GCD(3,5)=1, GCD(12,60)=12, and GCD(12,90)=6. The greatest common divisor GCD(a,b,c,...) can also be defined for three or more positive integers as the largest divisor shared by all of them. Two or more positive integers that have greatest common divisor 1 are said to be relatively prime to one another, often simply just referred to as being relatively prime. http://mathworld.wolfram.com/GreatestCommonDivisor.html The rest of the page avoids mentioning anything about negative values. There are five graphs on the page, all five are limited to only positive values. Mathworld does show one thing that suggests an interpretation for the GCD of negative values: The GCD is distributive GCD(ma,mb)=mGCD(a,b) which tells us that: GCD(-x, -y) = -GCD(x, y) And yet, Mathematica has: GCD(-x, -y) = GCD(x, y) the very opposite of what Mathworld says, despite coming from the same people. http://functions.wolfram.com/IntegerFunctions/GCD/04/02/01/ The Collins Dictionary of Mathematics (second edition, 2002) says: highest common factor, greatest common factor, or greatest common divisor (abbrev hcf, gcf, gcd) n, an integer d that exactly divides (sense 2) two given integers a and b, and is such that if c divides a and b, then c divides d; this definition extends to finite sets of integers and to integral domains. For example, the highest common factor of 12, 60 and 84 is 12. Yet again, we have no clear definition for negative values. Here's an example using Euclid's algorithm to calculate the GCD of negative numbers, and sure enough, you get a negative result: https://answers.yahoo.com/question/index?qid=20111021023909AA8bCjB Wikipedia, on the other hand, defines GCD: In mathematics, the greatest common divisor (gcd), also known as the greatest common factor (gcf), highest common factor (hcf), or greatest common measure (gcm), of two or more integers (when at least one of them is not zero), is the largest positive integer that divides the numbers without a remainder. https://en.wikipedia.org/wiki/Greatest_common_divisor So: - Mathworld says that GCD of two negative numbers is a negative number; - but Mathematica says that GCD of two negative numbers is a positive; - Wikipedia agrees with Mathematica and disagrees with Mathworld; - Euclid's algorithm returns negative values for the GCD of two negatives; - Collins Dictionary gives a definition which is met by either positive or negative results. -- Steven -- https://mail.python.org/mailman/listinfo/python-list

The default protocol in a browser is http. If you're not running a server on

I also don't run Windows any more so I might have the drive letter part wrong.

It looks to me as if your default association is set to Notepad rather
than a web browser. Try opening one of the browsers' settings pages
and making it your default browser. In Chrome, that's
chrome://settings/ and it's near the bottom; in Firefox, go to
Tools|Options, Advanced, and it's on the General tab. (They might
check on startup and offer to make themselves default, which would
save you some trouble.)

Receiving large files with @tornado.web.stream_request_body
I was using tornado 3 before. I see that file streaming was included in version 4. This is something I need for posting large files. I have a problem receiving multiple files with a single POST request. Client side could be something like this: form action=/postfiles First file: input type=file name=fname1br Second file: input type=file name=fname2br Third file: input type=file name=fname3br input type=submit value=Submit /form Suppose the user has seleted 3 large ISO files, I would like to stream them into files on the server side. This is what I was trying: @tornado.web.stream_request_body class PostFilesHandler(tornado.web.RequestHandler): def post(self): for postfile in self.request.files: print(File info:,postfile) # There is no postfile[body] here!!! def prepare(self): self.temp_file = tempfile.NamedTemporaryFile(delete=False) def data_received(self, chunk): self.temp_file.write(chunk) # This is great but which file is this??? The problem is obvious: the data_received method receives raw data, but how do I tell when data body for a file ends and another begins? How can I save the body of all posted files into different named temp files, and then access them from from the post() method? The main reason for using this is to limit memory usage. Some files might be GB sized and I don't want to store them in memory. Can please someone point me to a working example?

Re: Best way to deal with different data types in a list comprehension
Larry Martell wrote:
I have some code that I inherited:
' '.join([self.get_abbrev()] +

It's already broken. It gives a Syntax Error part way through:
py ' '.join([self.get_abbrev()] +
...[str(f['value')
File stdin, line 2
[str(f['value')
^
SyntaxError: invalid syntax
Please copy and paste the actual code, don't retype it.
This is my guess of what you actually have, reformatted to make it more
clear (at least to me):
' '.join(
[self.get_abbrev()] +
[str(f['value']) for f in self.filters if f.has_key('value')]
).strip()
I *think* that the call to strip() is redundant. Hmmm... perhaps not, if the
self.get_abbrev() begins with whitespace, or the last f['value'] ends with
whitespace. You should consider removing that call to .strip(), but for now
I'll assume it actually is useful and leave it in.
First change: assuming the filters are dicts, do the test this way:
' '.join(
[self.get_abbrev()] +
[str(f['value']) for f in self.filters if 'value' in f]
).strip()
Now, the *right* way to fix your problem is to convert the whole application
to use unicode strings everywhere instead of byte strings. I'm guessing you
are using Python 2.6 or 2.7.
You say it broke when given some non-ascii data, but that's extremely
ambiguous. {23: 42} is non-ascii data. What exactly do you have, and where
did it come from?
My *guess* is that you had a Unicode string, containing characters which
cannot be converted to ASCII.
py str(u'Ωπ')
Traceback (most recent call last):
File stdin, line 1, in module
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1:
ordinal not in range(128)
I changed the str(f['value']) line to f['value'].encode('utf-8'),
Hmmm, I'm not sure that's a good plan:
py u'Ωπ'.encode('utf-8')
'\xce\xa9\xcf\x80'
Do you really want to find arbitrary bytes floating through your strings? A
better strategy is to convert the program to use unicode strings
internally, and only convert to byte strings when you read and write to
files.
But assuming you don't have the time or budget for that sort of re-write,
here's a minimal chance which might do the job:
u' '.join(
[self.get_abbrev()] +
[unicode(f['value']) for f in self.filters if 'value' in f]
).strip()
That works correctly for random objects and ASCII byte strings:
py unicode([1, 2, 3])
u'[1, 2, 3]'
py unicode('bytes')
u'bytes'
Alas, it will fail for non-ASCII byte strings:
py unicode('bytes \xFF')
Traceback (most recent call last):
File stdin, line 1, in module
UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 6:
ordinal not in range(128)
Here's a version which prefers byte-strings, but should be able to handle
everything you throw at it:
' '.join(
[self.get_abbrev()] +
[
(x.encode('utf-8') if isinstance(x, unicode) else x)
for x in (f['value'] for f in self.filters if 'value' in f)
]
).strip()
Note the use of a generator expression inside the list comp.

now again input the code:

the x.grow() will output

now what i want to do is :
1.keep return(self.res) in grow method.
2.it is my target that when run the code:
import analyse
x=analyse.status()
x.grow()

The Collins Dictionary of Mathematics (second edition, 2002) says:

n, an integer d that exactly divides (sense 2) two given
integers a and b, and is such that if c divides a and b,
then c divides d; this definition extends to finite sets
of integers and to integral domains. For example, the
highest common factor of 12, 60 and 84 is 12.
Yet again, we have no clear definition for negative values.
Well, this definition would imply that gcd(a, b) should always return
*two* results, one positive and one negative. I don't think anybody
wants that. It would make more sense to standardize on one of them,
and if we take sqrt as an example, then the result should be positive.
Here's an example using Euclid's algorithm to calculate the GCD of negative
numbers, and sure enough, you get a negative result:
https://answers.yahoo.com/question/index?qid=20111021023909AA8bCjB
This depends entirely on your implementation of the modulo operation,
which is an issue of computing since the operator is not used in
mathematics. The algorithm itself only specifies at each step to
solve the equation R_{n-2} = Q * R_{n-1} + R_{n}, such that |R_{n}|
|R_{n-1}|. For any given input there can be many possible solutions,
both positive and negative, regardless of the signs of the inputs, and
it doesn't matter which solution you choose. So one could implement
Euclid's algorithm to return either a positive or negative result for
any arbitrary pair of integers.

ThreadPoolExecutor - callback guaranteed to run in same thread as the submitted function?
Hello,
In the ThreadPoolExecutor (TPE), is the callback always guaranteed to run in
the same thread as the submitted function?
For example, I tested this with the following code. I ran it many times and it
seemed like `func` and `callback` always ran in the same thread.
import concurrent.futures
import random
import threading
import time
executor = concurrent.futures.ThreadPoolExecutor(max_workers=3)
def func(x):
time.sleep(random.random())
return threading.current_thread().name
def callback(future):
time.sleep(random.random())
x = future.result()
cur_thread = threading.current_thread().name
if (cur_thread != x):
print(cur_thread, x)
print('main thread: %s' % threading.current_thread())
for i in range(1):
future = executor.submit(func, i)
future.add_done_callback(callback)
However, it seemed to fail when I removed the `time.sleep(random.random())`
statements, i.e. at least a few `func` functions and `callbacks` **did not**
run in the same thread.
For a project that I am working on, the callback must always run on the same
thread as the submitted function, so I wanted to be sure that this is
guaranteed by TPE. (And also the results of the test without the random sleep
seemed puzzling).
I looked at the source code for executors (see
https://hg.python.org/cpython/file/6d44906344f4/Lib/concurrent/futures/_base.py#l297)
and it does not seem like we switch the thread to the main thread before we
run the callback. But just wanted to be sure.
Any insight would be appreciated!
Thanks,
Praveen

Thank you again !!!
I managed to run the server as as service with help of sample code provided in
http://stackoverflow.com/questions/32404/is-it-possible-to-run-a-python-script-as-a-service-in-windows-if-possible-how
.
I found some problem in stopping the service. I feel it because of
socket.accept() which blocks. This the class where I implemented the server in
the main method.
class TraxServerSvc (win32serviceutil.ServiceFramework):
_svc_name_ = Testserver
_svc_display_name_ = Pytestserver
def __init__(self,args):
win32serviceutil.ServiceFramework.__init__(self,args)
self.hWaitStop =
win32event.CreateEvent(None,0,0,None)
self.sloop = True
self.serversock = 0
def SvcStop(self):
self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
win32event.SetEvent(self.hWaitStop)
self.sloop = False
def SvcDoRun(self):
servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,
servicemanager.PYS_SERVICE_STARTED, (self._svc_name_,''))
self.main()
def main(self):
self.serversock = socket.socket(socket.AF_INET,
socket.SOCK_STREAM)
self.serversock.bind(server_config())
self.serversock.listen(5)
while
(win32event.WaitForSingleObject(self.hWaitStop, 0) == 258):
try:
clientsock,
addr = self.serversock.accept()
Pysconfig.logger.info('...connected from: %s', addr) # logging
thread.start_new_thread(handler, (clientsock, addr))
Pysconfig.logger.info('Thread ID: %s', thread.get_ident()) # logging
except socket.error, msg:
Pysconfig.logger.info('Failed to create socket. Error code: ' + str(msg[0]) + '
, Error message : ' + msg[1])
pass
self.serversock.shutdown(socket.SHUT_RDWR)
self.serversock.close()
servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,
servicemanager.PYS_SERVICE_STOPPED, (self._svc_name_,''))
if __name__ == '__main__':
win32serviceutil.HandleCommandLine(TraxServerSvc)
When win32event.WaitForSingleObject(self.hWaitStop, 0) method returns zero , I
need to quit the while loop to stop the service. But in the above case, since
it blocks in accept , I need to make connection from client to completely stop
service.

It looks to me as if your default association is set to Notepad rather

String representations of numbers and approximate equality
Yes, it's another how can I see if two numbers are approximately equal thread, but this time I have a concrete definition of approximately equal... and they're Decimals, not floats. I have a number of files (this is an ongoing thing) in which there are two columns of numbers. One of them should be equal to the other times some factor which the program knows from elsewhere. All the numbers are represented as strings of ASCII decimal digits, possibly including a U+002E decimal point. Something like this: # (these are calculated on factor 30) [0.75, 22.5] [0.80, 24] [4.73, 142] The definition of valid is that, within the rounding they've been given, the values are correct. The first two are strictly correct; the third would be 141.9 with full accuracy but 142 is deemed good enough. But this should fail: [0.1, 10] 0.1 * 30 should be 3, not 10; and 10 / 30 should be 0.333, not 0.1; therefore this is wrong. This is a san-check for human-entered data, so sloppiness is necessary. I just want to have a chance to catch obvious typos and such. In theory, I think, a decimal.Decimal context should be able to do what I want here - but I'm not particularly familiar with it. Performance isn't critical, so stupid techniques that work on the actual string representation would be fine too. In general, the numbers will be fairly small. Maybe 3-4 digits before the decimal point, and probably not more than 2-3 after. Not sure if that makes things any easier or not. All advice appreciated!

Others allow it to be negative. I can't find a good source for allowing it to be negative, though. Clearly, the primary use of the function is on the positive integers, with the negatives being an extension. Mathworld does show one thing that suggests an interpretation for the GCD of negative values: The GCD is distributive GCD(ma,mb)=mGCD(a,b) which tells us that: GCD(-x, -y) = -GCD(x, y) And yet, Mathematica has: GCD(-x, -y) = GCD(x, y) the very opposite of what Mathworld says, despite coming from the same people. This is most likely simply them dropping the constraint that m must be non-negative. Wikipedia, for example, specifies it under Properties. The Collins Dictionary of Mathematics (second edition, 2002) says: highest common factor, greatest common factor, or greatest common divisor (abbrev hcf, gcf, gcd) n, an integer d that exactly divides (sense 2) two given integers a and b, and is such that if c divides a and b, then c divides d; this definition extends to finite sets of integers and to integral domains. For example, the highest common factor of 12, 60 and 84 is 12. Yet again, we have no clear definition for negative values. As pointed out, this definition always yields two values (positive and negative), even for positive a and b, so there's nothing special for negative a or b. Typically, I've seen this augmented with choose the positive one to get a single value. Here's an example using Euclid's algorithm to calculate the GCD of negative numbers, and sure enough, you get a negative result: The algorithm is pretty irrelevant here. gcd's not defined by a particular algorithm to calculate it. From everything that I've seen, mathematicians consider the gcd to be always positive. Now, that's not saying that fraction should implement the mathematical gcd, if it doesn't need it. That should be its own argument, though; it doesn't help to add false doubt about what the gcd of negative numbers should be. Cheers, Johann -- https://mail.python.org/mailman/listinfo/python-list

All four that I have so far looked at have definitions that lead to gcd(a, b) for integers being equal to gcd(|a|, |b|). I hope to visit a University library shortly to review more. Does anyone know of such a reference that uses a definition that conflicts with gcd(a, b) for integers being equal to gcd(|a|, |b|)? I doubt you'll find an advanced mathematical text that has such a definition. I think most abstract algebra texts would give a definition equivalent to saying that for any integers n and m the ideal generated by n and m is equal to the principal ideal generated by gcd(n,m); that is the heart of the matter mathematically, and this definition generalizes to other so-called principal ideal domains than the integers. (Don't want to Google for ideal and principal ideal? OK: an ideal is a subset of the integers closed under addition of any two of its elements, and under multiplication of any of its elements by any integer; a set of integers generates an ideal if that ideal is the intersection of all ideals containing that set, and a principal ideal is an ideal generated by a singleton set. For more elaboration, though, I'm going to point you at the internet, or better, some of those advanced texts in the library.) After working through what the definitions of ideals and principal ideals imply for the the definition above of gcd, you get the statement that k is the (or, better, a) gcd of n and m if and only if k divides n and m, and any other integer that divides both n and m divides k. The upshot is that, mathematically, gcd is only defined up to a change of sign, which helps explain why references may disagree with each other. Some authors may impose the restriction than gcd(n,m) = 0 for all n and m (which does have the advantage that then greatest really means greatest and not just greatest absolute value), but that isn't really a necessary part of the definition as far as the mathematically important properties of gcd are concerned. All that the abstract algebra requires is that |gcd(n,m)| = |gcd(|n|,|m|)|. So implementations of gcd that sometimes return a negative value are not, it seems to me, mathematically broken, though they might violate the principle of least surprise. for-whatever-it's-worth'ly-yrs, R.

For your edification: modify your command to be this: command = which ruby; echo $PATH; ruby run_my_command.rb and see if the output says what you expect. From the behaviour you describe I would expect that the GUI program, when it fails, is not being invoked from your command line but from some menu or suchlike. Further, I would guess that the invoking program (window manager, whatever) does not have ruby in its $PATH. This same effect obtains when you use the full path to ruby (usually a bad idea because your script may not work on another system where ruby is somewhere different) because like $PATH, the ruby search path also lacks the directories where the modules reside. When you run it from your command prompt or from the python interpreter your environment is already set up with this extra information.

[issue22477] GCD in Fractions
New submission from Brian Gladman: There is a discussion of this issue on comp.lang.python The function known as 'the greatest common divisor' has a number of well defined mathematical properties for both positive and negative integers (see, for example, Elementary Number Theory by Kenneth Rosen). In particular gcd(a, b) = gcd(|a|, |b|). But the Python version of this function in the fractions module doesn't conform to these properties since it returns a negative value when its second parameter is negative. This behaviour is documented but I think it is undesirable to provide a function that has the well known and widely understood name 'gcd', but one that doesn't match the behaviour normally associated with this function. I hence believe that consideration should be given to changing the behaviour of the Python greatest common divisor function to match the mathematical properties expected of this function. If necessary a local function in the fractions module could maintain the current behaviour. -- components: Library (Lib) messages: 227410 nosy: b...@gladman.plus.com priority: normal severity: normal status: open title: GCD in Fractions type: behavior versions: Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22477 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22477] GCD in Fractions
Mark Dickinson added the comment: The current `gcd` definition is almost accidental, in that it just happens to be what's convenient for use in normalisation in the Fraction type. If people are using it as a standalone implementation of gcd, independent of the fractions module, then defining the result to be always nonnegative is probably a little less surprising than the current behaviour. BTW, I don't think there's a universally agreed definition for the extension of the gcd to negative numbers (and I certainly wouldn't take Rosen's book as authoritative: did you notice the bit where he talks about 35-bit machines being common?), so I don't regard the fraction module definition as wrong, per se. But I do agree that the behaviour you propose would be less surprising. One other thought: if we're really intending for gcd to be used independently of the fractions module, perhaps it should be exposed as math.gcd. (That would also give the opportunity for an optimised C version.) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22477 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Sadly even some maths books don't cover this at all but then go on to rely on the co-prime test gcd(a, b) == 1 even when a and/or b can be negative. So I would agree that it is easy to conclude that the gcd is not defined for negative numbers. But, of those maths texts that explicitly cover the behaviour of the gcd for negative numbers, I do not know of any that do not define gcd(a, b) to be gcd(|a|, |b|). One other thought: if we're really intending for gcd to be used independently of the fractions module, perhaps it should be exposed as math.gcd. (That would also give the opportunity for an optimised C version.) To me it makes more sense to put this in math as this is where I would expect to find it.

[issue22477] GCD in Fractions
Mark Dickinson added the comment: I will willingly supply more references if you need them. I don't. :-) I've taught more elementary number classes and reviewed more elementary number theory texts (including Rosen's) than I care to remember, and I have plenty of my own references. I stand by my assertion that the fractions module gcd is not wrong: it returns 'a' greatest common divisor for arbitrary integer inputs. A bit more: the concept of greatest common divisor is slightly ambiguous: you can define the notion of a greatest common divisor for an arbitrary commutative ring-with-a-1 R: c is a greatest common divisor of a and b if c is a common divisor (i.e. c divides a and c divides b, where x divides y is synonymous with y is a multiple of x), and any other common divisor divides c. No ordering is necessary: greatest here is with respect to the divisibility lattice rather than with respect to any kind of total ordering. One advantage of this definition is that it makes it clear that 0 is a greatest common divisor of 0 and 0. If further R is an integral domain, then it follows immediately from the definition that any two greatest common divisors of a and b (if they exist) are associates: a is a unit times b. In the particular case where R is the usual ring of rational integers, that means that the greatest common divisor of two numbers a and b is only really defined up to +/-; that is, the sign of the result is unimportant. (An alternative viewpoint is to think of the gcd, when it exists, as a principal ideal rather than an element of the ring.) See https://proofwiki.org/wiki/Definition:Greatest_Common_Divisor/Integral_Domain for more along these lines. So you're using one definition, I'm using another. Like I said, there's no universal agreement. ;-). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22477 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Mark Dickinson added the comment: Well we will just have to agree to disagree on this :-) Sure. In the mean time, would you be interested in writing a patch targeting Python 3.5?

[issue22480] SystemExit out of run_until_complete causes AttributeError when using python3 -m
New submission from chrysn: the attached test.py snipplet, which runs an asyncio main loop to the completion of a coroutine raising SystemExit, runs cleanly when invoked using `python3 test.py`, but shows a logging error from the Task.__del__ method when invoked using `python3 -m test`. the error message (attached as test.err) indicates that the builtins module has already been emptied by the time the Task's destructor is run. i could reproduce the problem with an easier test case without asyncio (destructoretest.py), but then again, there the issue is slightly more obvious (one could argue a don't do that, then), and it occurs no matter how the program is run. i'm leaving this initially assigned to asyncio, because (to the best of my knowledge) test.py does not do bad things by itself, and the behavior is inconsistent only there. -- components: asyncio messages: 227440 nosy: chrysn, gvanrossum, haypo, yselivanov priority: normal severity: normal status: open title: SystemExit out of run_until_complete causes AttributeError when using python3 -m versions: Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22480 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
