Re: An object is an instance (or not)?
Gregory Ewing wrote: Mario Figueiredo wrote: I couldn't think of a way to demonstrate that a class object does not participate in its own inheritance rules. Only instances of it can. I think I may see where your reasoning is going astray. You think that an instance inherits methods from its class in the same way that a subclass inherits methods from its base class. In fairness, inherit is standard terminology for the way instances get their behaviour from their class. Also, you can override methods *on the instance*: py class Parrot(object): ... def talk(self): ... print(Polly wants a cracker!) ... py polly = Parrot() py polly.talk() Polly wants a cracker! py from types import MethodType py polly.talk = MethodType( ... lambda self: print(Polly wants a spam sandwich!), polly) py polly.talk() Polly wants a spam sandwich! But thinking of the instance-class relationship as an inheritance relationship is misleading. It's more accurate to say that a class *defines* the methods that its instances have. The class inherits methods from its base class, but those methods still apply to instances of the class, not the class itself. I won't speak for other OOP models, but I don't think that is true in Python. In Python, obj.talk performs the following (grossly simplified) process: * search the instance for an attribute talk * search the class * search all the base classes * fail (simplified because I have ignored the roles of __getattr__ and __getattribute__, of metaclasses, and the descriptor protocol) That's more or less the same as what happens whether obj is a class object or a non-class object. I don't know what attribute lookup *literally* uses the exact same code for looking up attributes on an instance or a class, but it wouldn't surprise me if it does. That doesn't mean the class itself can't be given methods, though. The methods of the class are defined by its metaclass, and the metaclass inherits methods from *its* base class, etc. The normal way of giving a class methods that are callable from the class is to define them on the class with the classmethod or staticmethod decorators. Using a metaclass is usually overkill :-) Here's a diagram: +--+ ++ | type | | base class | +--+ ++ ^ ^ | subclass of | subclass of | | +---+ +---+ +--+ | metaclass |-| class |-| instance | +---+ instance of +---+ instance of +--+ It should be clear from this that the relationship between an instance and its class is exactly the same as that between a class and its metaclass, including inheritance relationships. The diagram can be extended indefinitely far to the left -- the metaclass could be an instance of a meta-metaclass, etc. (Although there's an old standing joke in the Python world that metaclasses make your head explode, so I hate to think what a meta-metaclass would do -- probably take out a whole floor of the office building you work in. Meta-meta-metaclasses are right out.) An early essay on Python metaclasses was subtitled The Killer-Joke. -- Steven -- https://mail.python.org/mailman/listinfo/python-list

OSCON 2015 CfP DEADLINE Feb 2
OSCON (O'Reilly Open Source Conference) will be held in Portland, OR July 20-24. The Call for Proposals is now open with a DEADLINE of Monday February 2: http://www.oscon.com/open-source-2015/public/cfp/360 O'Reilly has completely reorganized OSCON. Instead of focusing on individual technologies, there are a bunch of themes: * Identity - An emerging and nuanced facet in the digital age and an exciting cross-functional track at OSCON 2015. * Security - We'll explore security from top to bottom, offering frameworks and libraries, strategies for testing, and field reports of both security failure and success. * Privacy - Computers remember our interactions at a level of detail the physical world never has. Do we want to be remembered, and for how long? * Performance - From compilation and interpreter time to DOM manipulation, browser responsiveness, and network latency, we'll explore performance in all its facets. * Mobility - We'll look at what it means to have a successful mobile game plan, from wearables to native apps. * People - Making projects work requires communications, collaboration, and respect; we'll look at the ways a new generation of tools and approaches can help you work. * Architecture - Software architecture is a massive multidisciplinary subject, covering many roles and responsibilities--and a key position in the success of any business. * Scale - You've created a great web interface that is well designed, secure, and works well in a beta with 100 consumers, but how about 10,000, 1,000,000, or more? * Storage - Find your way among the myriad choices for storing data and optimizing your systems for stability, distribution, convenience, and performance. * Teaching - You want to share your best practices, projects, and tools with the world, but how do you go about sharing this knowledge? We'll examine learning theory and methods of teaching. * Design - It's critical for success; learn how to incorporate design best practices from the beginning of your project rather and all the way through. * Solve - Harness the power of math to manipulate, secure, and create data. * Data - Let's tackle data's continued, growing influence over the entire business world and how you can make it work for you. * Foundations - A strong foundation in computational thinking, problem solving, and programming best practices makes for a successful programmer.

I don't know what the difference is between object and instance. An object is an instance of a class. The two words are interchangeable as far as I know. Not in English grammar, IMO. To say “foo is an instance” implies the sentence isn't finished; the term “instance” only makes sense in the context of a relationship to some class. To say “foo is an object” doesn't have that implication. I'm sure that there is a grammatical term for this, but I don't know it. Regardless of the terminology though, foo is an instance is a complete sentence fragment: foo is an instance (of some unspecified class) is the same grammatical construct as: George is a soldier (of some unspecified army) Pluto is a cartoon animal (of some unspecified species) Bearhugger's Old Peculiar is a drink (of some unspecified type) Herbie is a car (of some unspecified make and model) etc. In Java, the term object as a synonym for instance is unambiguous, because in Java all classes are subclasses of Object, and no classes are themselves instances of a class. But that's not the case with Python. A common mistake is to believe that OOP is a well-defined term. It's not it's a collection of ideas that are expressed slightly differently in each language. Right. The common meaning of “object” shared by all OOP systems is surprisingly small. Agreed. There really is no widespread agreement on what OOP means *precisely*. Wikipedia states: Attempts to find a consensus definition or theory behind objects have not proven very successful and there is little agreement of the fundamental features of OOP: http://en.wikipedia.org/wiki/Object- oriented_programming#Fundamental_features_and_concepts [...] In Python, every class is an object. Every class has the full range of behaviour that we expect of objects. A class just has the additional feature that it can be instantiated. We can also define an is-a relationship between classes and their instances: [1, 2, spam] is-a list; but not list is-a [1, 2, spam] However, in Python that breaks down at the very bottom of the inheritance hierarchy, thanks to the circular relationship between type and object: py isinstance(type, object) True py isinstance(object, type) True type is-a object object is-a type -- Steve -- https://mail.python.org/mailman/listinfo/python-list

I know about the xlrd module to get data from excel and I'm also aware
about the ETE toolkit (which is more specific for bioinformatics, but I
guess can suitable fill the need).
Does anyone recommend any other path other than scripting through these
two modules?
Is there any more suitable module/example/project out there that would
achieve the same result?
The reason for parsing is because the need behind is to create documents
edited in excel but typeset in LaTeX, therefore my script will spill out
\chapter, \section and so forth based on the tree structure.
Every node will have some text and some images with a very light markup
like mediawiki that I can easily convert into latex.
Hope I've not been too confusing.
Thanks for any pointer/suggestion/comment.

parsing tree from excel sheet

Does anyone recommend any other path other than scripting through these two modules? Is there any more suitable module/example/project out there that would achieve the same result? The reason for parsing is because the need behind is to create documents edited in excel but typeset in LaTeX, therefore my script will spill out \chapter, \section and so forth based on the tree structure. Every node will have some text and some images with a very light markup like mediawiki that I can easily convert into latex. Hope I've not been too confusing.

It's the Sub instance object that does not have it. What do you think Sub object means? I think it means the Sub class, which is an object. And Python 3.3 agrees with me: py class Sub(object): ... pass ... py isinstance(Sub, object) True Sub is also an instance of type. And object is an instance of type, type is an instance of object, and type is a subclass of object. But object is not a subclass of type. However it is an instance of type. Are we confused yet? There is a sense, taken from Java in particular, that object is synonymous for instance. For example, Oracle's documentation for classes says: A class contains constructors that are invoked to create objects from the class blueprint. http://docs.oracle.com/javase/tutorial/java/javaOO/constructors.html But you won't find any Java documentation referring to the class itself as an object. Java has no metaclasses, classes are not instances of a metaclass, and so classes are never instances. Classes are classes, objects are instances of a class, and that is all there is to it. But in Python, object and instance are more ambiguous, thanks to metaclasses. Instances of a metaclass are classes, hence classes are instances as well as classes: py isinstance(Sub, type) True Sub is an instance of the class type. And because classes themselves are first-class (ha ha!) values, like ints, strings, lists etc., classes are objects. All classes (in Python 3) are instances of a class (the metaclass), but not all instances are classes. Obviously this is rather confusing, but fortunately metaclasses (other than type itself) are rare, so *most of the time* we can get away with Java-like terminology, and pretend that classes are distinct from instances rather than being just another kind of instance (of the metaclass). But what we cannot do is pretend that object means instance, because all classes are objects. Alas, habits from other languages leak in, and the Javaesque terminology Foo object meaning an instance of Foo sometimes gets used, even though Foo object should refer to the object called Foo, namely the class object itself. The unfortunate ambiguity is that sometimes Foo object gets used to mean Foo, and other times it gets used to me some instance of Foo. We say: the None object has no state and the function requires an int object as argument. Sub itself is not a Sub object, Sub itself is not *a* Sub object, it is *the* Sub object, just as 42 is *the* object with type int and value forty-two. it is a type object. instance is implicit in the phrase foo object. Alas, classes *are* instances, of their metaclass, so Sub object could refer to an instance of Sub (using the Javaesque terminology) or Sub itself (using more Pythonistic terminology). -- Steven -- https://mail.python.org/mailman/listinfo/python-list

Yes. Unfortunately, it's still not really completely clear. Sub instance would avoid this confusion for everyone. It really is completely clear. Nobody is confused but you. Ironically, your denial of a pretty clear case of ambiguity demonstrates that if anyone is confused, it is you.

I agree that in *common situations*, it is useful to pretend that Python is like Java, and draw a distinction between classes and instances.

A common mistake is thinking just because OOP has different implementations, it doesn't have a cohesive set of well described rules and its own well defined terminology. Alas, this is not a mistake. As I posted in a reply to Ben, OOP does not have a cohesive set of rules and well-defined terminology. I don't know what a not fully realized object is. A fully realized object, in an object oriented paradigm, is an object containing or pointing to data and the methods to act on that data. It's an instance of a class. In Python, classes meet that definition too. A class in Python is a value which can contain data (or point to data), and it has methods which act on that data. Classes in Python themselves have a class, which we call the metaclass, and classes inherit behaviour from their class just as integer instances inherit behaviour from their class, int. A *not* fully realized object is possible in Python, since Classes are first-class objects, despite not being able to participate in OOP. What does participate in OOP mean? Means the object is capable of participating in inheritance and/or polymorphism. An instance of an object is capable of doing so, per its class definitions. Whereas a Python class object is not. Class objects are capable of participating in inheritance. A class can have multiple metaclasses. They can even have multiple inheritance of metaclasses.

But thinking of the instance-class relationship as an inheritance relationship is misleading. It's more accurate to say that a class *defines* the methods that its instances have. The class inherits methods from its base class, but those methods still apply to instances of the class, not the class itself. That doesn't mean the class itself can't be given methods, though. The methods of the class are defined by its metaclass, and the metaclass inherits methods from *its* base class, etc. Here's a diagram: +--+ ++ | type | | base class | +--+ ++ ^ ^ | subclass of | subclass of | | +---+ +---+ +--+ | metaclass |-| class |-| instance | +---+ instance of +---+ instance of +--+ It should be clear from this that the relationship between an instance and its class is exactly the same as that between a class and its metaclass, including inheritance relationships. The diagram can be extended indefinitely far to the left -- the metaclass could be an instance of a meta-metaclass, etc. (Although there's an old standing joke in the Python world that metaclasses make your head explode, so I hate to think what a meta-metaclass would do -- probably take out a whole floor of the office building you work in.

The thing that bothers me is that many people, some of them with maybe 20 years of Python experience, have repeatedly stated Python concepts with respect to the terms class, instance and object. Instead of accepting their knowledge of the language and gracefully stepping back, you've carried on until the twist of knots would make any boy scout proud. Condescending much? I'm not one to lower to arguments from authority. Sorry. Never have, never will. Neither I adopt such attitude on those programming languages in which I am myself an authoritative source. I respect knowledge as anyone else. But I also specifically asked for arguments that could show me the Python way. I have a desire to understand. It's not just a matter of accepting the word of someone who is more experienced than me. That does not do any good to anyone. I'm not trying to change anything, neither I'm a OOP fanatic like some tried to accuse me. I'm just trying to understand. Do *you* understand that? I may have sounded ignorant to you. It's something I cannot avoid, because while I try to argue this issue, I do it from the position of someone who is still learning the Python language syntax and semantics. But I'm much more than what you may think. And I would like to be treated with a little more respect. Like you I'm a software developer and, probably like you, I have decades of software development as a profession on my back. But some of the arguments in here (and yours too) have done very little to help me understand the language semantics on this particular issue. Purportedly, or perhaps innocently due to my clumsiness, some folks in here argue with little more than but a class object is an instance of 'type'. They choose to ignore that class objects are clearly a special type of object unlike the instances they help define. Like in so many debates, there's unfortunately always a desire to ignore or avoid other side that is arguing with us. Thankfully, I am now starting to understand the semantics. Folks like Ben, Steven or Ian (apologies to a couple others I am missing. Can't remember your names and having an hard time looking through past posts) have helped tremendously by leaving smugness aside, adopting an educational attitude towards a clearly confused person, and -- I would wager -- understanding that I'm asking questions, not trying to set new ways.

I am totally new to Python and please accept my apologies upfront for
potential newbie errors. I am trying to parse a 'simple' web page:

accept button. After accepting TC I would like to scrape some data from that
follow up page. It appears that when opening in a browser directly
http://flow.gassco.no/acceptDisclaimer I would get around that TC.
But not when I open the URL via beautifulsoap
My parsing/scraping tool is implemented in bs, but I fail to parse the
content as I am not getting around TC. When printing response.text from
BS, I get below code. How do I get around this form for accepting terms

Here is what I am doing:
#!/usr/bin/env python

def get_video_page_urls():
response = requests.get(index_url)
soup = bs4.BeautifulSoup(response.text)

var s = document.getElementsByTagName('script')[0];
s.parentNode.insertBefore(ga, s);

/script
Try clearing your browser cookies and then reopening the page, it should spit
you back to the TOC screen.
You can use the Session class to keep track of your cookies between requests:
with requests.Session() as s:
# Request sessionid cookie and store it in the current session
response = s.get('http://flow.gassco.no')
# Subsequent gets will now include the session cookie
response = s.get('http://flow.gassco.no/acceptDisclaimer')
A good place to start when debugging something like this is to open up the
developer tools in your browser (F12 in chrome/firefox) and observe the GET
requests that get sent out as you click on different buttons.

Can you explain what you see as the difference between spawn and fork in this context? Are you using Windows perhaps? I don't know anything obviously different between the two terms on Unix systems. On Unix, if you fork without exec*, and had threads open, threads abruptly terminate, resulting in completely broken mutex state etc., which leads to deadlocks or worse if you try to acquire resources in the forked child process. So in such circumstances, multiprocessing (in 2.7) is not a viable option. But 3.x adds a feature, spawn, that lets you fork+exec instead of just forking.

The Python implementation of RLock gets the thread identifier from the monkey-patched threading module, whereas the C implementation calls directly a C function to get the identifier which is incompatible with eventlet.

The languages you cite don't require extra type annotations because they already have the types in the function signatures.

Just open your eyes: Scala def addInt( a:Int, b:Int ) : Int Python def addInt( a:int, b:int ) - int: They're COMPLETELY different. In Scala they are *type declarations*, not annotations.

I somewhat arbitrarily changed the sizes of the buffers in _test_send with: rd.setsockopt(socket.SOL_SOCKET, socket.SO_RCVBUF, support.SOCK_MAX_SIZE // 3) wr.setsockopt(socket.SOL_SOCKET, socket.SO_SNDBUF, support.SOCK_MAX_SIZE // 3) The results were: test_send (__main__.SocketEINTRTest) ... rd SO_RCVBUF default was 8192, wr SO_SNDBUF default was 8192 len(data) = 50331651 sent = 5592405, written = 5592405 chunk = 5592405, total read = 5592405 chunk = 5592405, total read = 11184810 chunk = 5592405, total read = 16777215 sent = 16777215, written = 22369620 chunk = 5592405, total read = 22369620 chunk = 5592405, total read = 27962025 chunk = 5592405, total read = 33554430 chunk = 5592405, total read = 39146835 sent = 22369620, written = 44739240 chunk = 5592405, total read = 44739240 sent = 5592411, written = 50331651 chunk = 5592405, total read = 50331645 chunk = 6, total read = 50331651 ok test_sendall (__main__.SocketEINTRTest) ... rd SO_RCVBUF default was 8192, wr SO_SNDBUF default was 8192 len(data) = 50331651 chunk = 5592405, total read = 5592405 chunk = 5592405, total read = 11184810 chunk = 5592405, total read = 16777215 chunk = 5592405, total read = 22369620 chunk = 5592405, total read = 27962025 chunk = 5592405, total read = 33554430 chunk = 5592405, total read = 39146835 chunk = 5592405, total read = 44739240 sent = None, written = 50331651 chunk = 5592405, total read = 50331645 chunk = 6, total read = 50331651 ok test_sendmsg (__main__.SocketEINTRTest) ... rd SO_RCVBUF default was 8192, wr SO_SNDBUF default was 8192 len(data) = 50331651 sent = 5592405, written = 5592405 chunk = 5592405, total read = 5592405 chunk = 5592405, total read = 11184810 chunk = 5592405, total read = 16777215 chunk = 5592405, total read = 22369620 chunk = 5592405, total read = 27962025 sent = 27962025, written = 33554430 chunk = 5592405, total read = 33554430 chunk = 5592405, total read = 39146835 chunk = 5592405, total read = 44739240 sent = 16777221, written = 50331651 chunk = 5592405, total read = 50331645 chunk = 6, total read = 50331651 ok I dunno if a value that large will work in all environments, so the code to call setsockopt might need to be smarter. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23285 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Open file in default app and exit in Windows
I am using the following to open a file in its default application in Windows 7:
from subprocess import call
filename = 'my file.csv'
call('%s' % filename, shell=True)
This still leaves a python process hanging around until the launched app is
closed. Any idea how to get around?

So you commit often and push immediately. Solved. I distrust any backup strategy that requires explicit action by the user. I've seen users fail too often. (Including myself.) That tends to be my opinion and experience as well :) And that is where Drive is quite nice: its an automatic backup to an off-site backup that requires no user action. Having some form of source control is still needed however, as you don't get all the nice history with Drive, and don't have the atomic updates - typically, every save will be uploaded, even if that change itself will break everything as you haven't made the required changes to other files.

[issue23343] operator precedence table for `not x` has an operand, while the others do not
New submission from Hobs: Shouldn't the [operator precedence table](https://docs.python.org/3.4/reference/expressions.html#operator-precedence), 5th row, 1st column, just say `not` rather than `not` x? The other rows are identified by the keyword for the operator and don't include any operand(s). Is there some other expression that includes `not` that should have a different position in the precedence table? -- assignee: docs@python components: Documentation messages: 234919 nosy: Hobson.Lane, docs@python priority: normal severity: normal status: open title: operator precedence table for `not x` has an operand, while the others do not type: enhancement versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4, Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23343 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
