[ANN] Summer School Advanced Scientific Programming in Python in Munich, Germany
Advanced Scientific Programming in Python = a Summer School by the G-Node, the Bernstein Center for Computational Neuroscience Munich and the Graduate School of Systemic Neurosciences Scientists spend more and more time writing, maintaining, and debugging software. While techniques for doing this efficiently have evolved, only few scientists have been trained to use them. As a result, instead of doing their research, they spend far too much time writing deficient code and reinventing the wheel. In this course we will present a selection of advanced programming techniques, incorporating theoretical lectures and practical exercises tailored to the needs of a programming scientist. New skills will be tested in a real programming project: we will team up to develop an entertaining scientific computer game. We use the Python programming language for the entire course. Python works as a simple programming language for beginners, but more importantly, it also works great in scientific simulations and data analysis. We show how clean language design, ease of extensibility, and the great wealth of open source libraries for scientific computing and data visualization are driving Python to become a standard tool for the programming scientist. This school is targeted at Master or PhD students and Post-docs from all areas of science. Competence in Python or in another language such as Java, C/C++, MATLAB, or Mathematica is absolutely required. Basic knowledge of Python is assumed. Participants without any prior experience with Python should work through the proposed introductory materials before the course. Date and Location = August 31—September 5, 2015. Munich, Germany.

Classes - delegation question.
Hello guys,
I have a question about delegation coding pattern(I'm working with Python
3.4).
In order to describe my question , I'll provide particular example:
Let assume I have two classes written in module named person.py:
Case 1:
class Person:
def __init__(self, name, job = None, pay =0):
self.name = name
self.job = job
self.pay = pay
def lastName(self):
return self.name.split()[-1]
def giveRaise(self, percent):
self.pay = int(sel.pay * (1 + percent))
def __repr__(self):
return '[Person: %s, %s]' % (self.name, self.pay)
class Manager(Person):
def giveRaise(self, percent, bonus = .10):
Person.giveRaise(self, percent + bonus)
Case 2:
class Person:
the same...
class Manager:
def __init__(self, name, pay):
self.person = Person(name, 'mgr', pay)
def giveRaise(self, percent, bonus = .10):
self.person.giveRaise(percent + bonus)
def __getattr__(self, attr):
return getattr(self.person, attr)
def __repr__(self):
return str(self.person)
I also used some test code proposed by the book:
if __name__ == '__main__':
bob = Person('Bob Smith')
sue = Person('Sue Jones', job='dev', pay=10)
print(bob)
print(sue)
print(bob.lastName(), sue.lastName())
sue.giveRaise(.10)
print(sue)
tom = Manager('Tom Jones', 5) # Job name not needed:
tom.giveRaise(.10)
print(tom.lastName())
print(tom)
As I can understand from the above code :
When code looks like in Case 1, it actually works with standard
inheritance model. (with sub and super-class definitions).
Also according to the book:
***
This code leverages the fact that a class's method can always be called
either through
an instance (the usual way, where Python sends the instance to the self
argument
automatically) or through the class (the less common scheme, where you must
pass the
instance manually). In more symbolic terms, recall that a normal method call
of this
form:
instance.method(args...)
is automatically translated by Python into this equivalent form:
class.method(instance, args...)
***
Furthermore:
***
Python provides it automatically only for calls made through an instance.
For calls
through the class name, you need to send an instance to self yourself; for
code inside
a method like giveRaise, self already is the subject of the call, and hence
the instance
to pass along.
Calling through the class directly effectively subverts inheritance and
kicks the call
higher up the class tree to run a specific version.
What is considered as a call in this context?
Is it a code inside class method?
For instance(relates to the Case 1):
def giveRaise(self, percent, bonus = .10):
Person.giveRaise(self, percent + bonus)
The call will be : Person.giveRaise(self, percent + bonus) ?
In such a case, when I create an instance:
tom = Manager('Tom Jones', 5)
and then invoke giveRaise method
tom.giveRaise(.10)
I essentially say this:
class.method(instance, args...)
Where class is Person and method is giveRaise and instance is tom?
Moreover, because of how it defined (a method giveRaise), I make a call
through the class name?
What is the call through instance?
Is it this one(according to Case 1):
class Person:
...
def giveRaise(self, percent):
self.pay = int(sel.pay * (1 + percent))
...
and then:
bob = Person('Bob Smith', 'dev', 3)
bob.giveRaise(.10) Is this call through instance?
Questions regard to Case 2 example:
class Person:
the same...
class Manager:
def __init__(self, name, pay):
self.person = Person(name, 'mgr', pay) ---
Initialization of Manager's attribute named 'self.person and embedding a
Person object.
def giveRaise(self, percent, bonus = .10): --
Defenition of Manager's method named giveRaise and according to the book:
self.person.giveRaise(percent + bonus) Intercept and
delegate
..
My question here is substantially the same:
On the one hand we embedding Person into Manager class,
On the other hand, when I write this code:
tom = Manager('Tom Jones', 5000)
I create an instance of Manager that have an attribute named: tom.person,
which in turn is a class named Person.
And when typing:
tom.giveRaise(.10)
I do kinda same thing.
For my assumption I say:
Person.giveRaise( percent + bonus) (when

The program shown below. I'm not sure why you would want to use a SAX parser for this. The advantage of incremental parsing is that you never have to have the whole document in memory at once. If you use it to construct some DOM-like structure from the document, then you're going to have the whole document in memory anyway, and you might as well just use one of the existing implementations (e.g. ElementTree) rather than reinventing your own. -- https://mail.python.org/mailman/listinfo/python-list

I think that this exception came from your SMTP server, not from
smtplib. Check your smtpd log.
You can try to send through that smtpd at another way (eg.
netcat) with that address - may be then you can check the result.

signal.signal handler arity check - PEP?
It strikes me as oddly dangerous that signal.signal() accepts callable handlers of the wrong arity: def timeout_cleanup(): ... signal.signal(signal.SIGALRM, timeout_cleanup) # I desire a TypeError here signal.alarm(PROCESS_TIMEOUT) ... time passes ... TypeError: timeout_cleanup() takes 0 positional arguments but 2 were given (Similar TypeError with different text under python 2.) The downside to current behavior is that the coding error is revealed only under certain conditions at runtime. In the example above, you don't know that your seatbelt is defective until you need it. Does anyone disagree with modifying signal.signal's behavior to raise a TypeError when given a user-defined handler of the wrong arity? Any code relying on this behavior is, IMO, contrived beyond plausibility. However, this change might break code not yet known to be incorrect. If no disagreements, patch or PEP? -Mike -- https://mail.python.org/mailman/listinfo/python-list

No need to do more troubleshooting, need to update the config.

And many SMTP deployments have pretty naive (shell) scripts or software with shell exits. So allowing those chars can cause more or less big security risks. For this reason it's likely that you will end in spam filters / black lists etc. because systems may assume you want to do some harm. So I would really rethink the requirements.

And many SMTP deployments have pretty naive (shell) scripts or software with shell exits. So allowing those chars can cause more or less big security risks. For this reason it's likely that you will end in spam filters / black lists etc. because systems may assume you want to do some harm. So I would really rethink the requirements. Your mileage may vary. But you have been warned. It's worth noting that the SMTP spec never says that every server must accept all characters. I could create a perfectly compliant mail server in which recipient names may not include the letter 'e', for instance.

Re: Is there a way to schedule my script?
Hi Juan, I don't know what platform you're on, but you've got several options. Mac: setup a launchd job, I use http://www.soma-zone.com/LaunchControl/ to do the setups Linux/unix: setup a cron job, depending on your distro launchd may also be an option. Windows: setup a scheduled job in ?? (I don't have a windows box around any more, but there was a Scheduled Jobs section in windows explorer back in the XP days. I assume it's still around. In all cases, you'll need to add a little code in your script to STOP at 11:59, but the OS can handle starting the script. The launchd option can also act as a watchdog to also restart the script if it fails for some reason. Hope this helps!

Re: Classes - delegation question.
Ivan Evstegneev webmailgro...@gmail.com writes:
I have a question about delegation coding pattern(I'm working with Python
3.4).
Unlike Java, Python supports multiple inheritance. This means
that you need delegation much more rarely in Python.
Python does not have much special support for delegation: usually,
you must delegate explicitely - maybe using a delagating decorator.
...
When code looks like in Case 1, it actually works with standard
inheritance model. (with sub and super-class definitions).
Also according to the book:
***
This code leverages the fact that a class's method can always be called
either through
an instance (the usual way, where Python sends the instance to the self
argument
automatically) or through the class (the less common scheme, where you must
pass the
instance manually). In more symbolic terms, recall that a normal method call
of this
form:
instance.method(args...)
is automatically translated by Python into this equivalent form:
class.method(instance, args...)
***
Furthermore:
***
Python provides it automatically only for calls made through an instance.
For calls
through the class name, you need to send an instance to self yourself; for
code inside
a method like giveRaise, self already is the subject of the call, and hence
the instance
to pass along.
Calling through the class directly effectively subverts inheritance and
kicks the call
higher up the class tree to run a specific version.
What is considered as a call in this context?
Something of the form expression(args...). I.e. any call of
a function or method.
The discussion above does not directly apply to your situation.
It targets more specifically the following case:
class Base:
...
def f(self, ...):
...
class Derived(Base):
...
def f(self, ...):
...
Base.f(self, ...)
...
i.e., you have two classes Base, and Derived where
Derived overrides the inherited f and its definition
involves the use of the inherited f. Inside the redefinition,
you must make explicit that you mean the inherited f and not
the f being defined. In those cases, you typically use
the pattern Base.f, meaning the f defined in Base.
However, you may use the form anywhere - its just rarer in other
cases.
It you use instance.f, then instance is automatically
passed as first argument to f; however, it you use
class.f, then nothing is passed on automatically as first
parameter. When class.f is finally called, you usually need
to pass an instance of class as first parameter explicitely.
Is it a code inside class method?
Usually, you use class.f inside the redefinition of f
in a derived class. But, you can use it anywhere (if you like).
For instance(relates to the Case 1):
def giveRaise(self, percent, bonus = .10):
Person.giveRaise(self, percent + bonus)
The call will be : Person.giveRaise(self, percent + bonus) ?
Yes.
In such a case, when I create an instance:
tom = Manager('Tom Jones', 5)
and then invoke giveRaise method
tom.giveRaise(.10)
I essentially say this:
class.method(instance, args...)
Where class is Person and method is giveRaise and instance is tom?
Yes.
Moreover, because of how it defined (a method giveRaise), I make a call
through the class name?
Loosely speaking, yes.
What is the call through instance?
Your tom.giveRaise. There tom is a Manager instance.
Is it this one(according to Case 1):
class Person:
...
def giveRaise(self, percent):
self.pay = int(sel.pay * (1 + percent))
...
and then:
bob = Person('Bob Smith', 'dev', 3)
bob.giveRaise(.10) Is this call through instance?
Yes.
...
Questions regard to Case 2 example:
class Person:
the same...
class Manager:
def __init__(self, name, pay):
self.person = Person(name, 'mgr', pay) ---
Initialization of Manager's attribute named 'self.person and embedding a
Person object.
def giveRaise(self, percent, bonus = .10): --
Defenition of Manager's method named giveRaise and according to the book:
self.person.giveRaise(percent + bonus) Intercept and
delegate
..
My question here is substantially the same:
On the one hand we embedding Person into Manager class,
On the other hand, when I write this code:
tom = Manager('Tom Jones', 5000)
I create an instance of Manager that have an attribute named: tom.person,
which in turn is a class named Person.
... is an instance of a class ...
And when typing:
tom.giveRaise(.10)
I do kinda same thing.

Guido van Rossum added the comment: Oh. I'd forgotten the PY3 situation is completely different from the PY2 situation. We're still stuck here in PY2 land where there's just the one import lock. I guess not even ctypes can help us find out whether the current thread is holding the import lock (which is the condition we're trying to test for so we can print the warning). Our current hack is to check lock_held() and if it is held wait for up to 5 second (in 10 msec increments) to see if it goes away -- if it doesn't go away it would seem we are holding it in the current thread and then we fail with a rude assert. If it does go away within that time we assume some other thread was doing some lazy importing and we hope they'll be done soon because the whole world is waiting for them.

[issue23073] Broken turtle example in Cmd documentation
New submission from bbc: The documentation page for the cmd module contains an example with the turtle module: https://docs.python.org/3.4/library/cmd.html#cmd-example It seems like the turtle module has changed quite a bit since the code was written, and exposes a Pen class instead of all the various movement functions.

A call like 'PyImport_ImportModuleNoBlock(this-is-not-a-legal-module-name)' will always fail with ImportError, but the exception message will be different if another thread holds the import lock.

[issue22926] asyncio: raise an exception when called from the wrong thread
STINNER Victor added the comment: Guido So in order to do correct diagnostics here we would have to add an owning thread pointer to every event loop; I didn't understand why this approach was not taken when the check was introduced. I was surprised that get_event_loop() was used for the check instead. Here is a patch checking the thread using threading.get_ident(). The check still works when set_event_loop(None) is used in unit tests. I created the issue #23074 for the change: get_event_loop() must always raise an exception, even when assertions are disabled by -O. -- asyncio requires thread support, it is already the case without my patch. For example, the event loop policy uses threading.Local. In the aioeventlet project, call_soon() writes a byte in the self pipe (to wake up the selector) if the selector is waiting for events; call_soon() is green thread safe. It is less efficient than calling forcing users to call explicitly call_soon_threadsafe(), but aioeventlet is written to be compatible with asyncio and eventlet, while these projects are very different. In the aiogevent and aioeventlet projects, I also store the current greenlet, but for a different purpose: ensure that yield_future() is not called in the greenlet running the event loop, which would blocking. -- Added file: http://bugs.python.org/file37483/check_thread.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22926 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19548] 'codecs' module docs improvements
Martin Panter added the comment: Here is a patch addressing many of the points raised. Please have a look and give any feedback. Beware I am not very familiar with the Restructured Text markup and haven’t tried compiling it. 1. Mentioned bytes-to-bytes and text-to-text in general right at the top. Any APIs (e.g. see Issue 20132) that don't support them should be pointed out as exceptions to the rule. 8. The underlying mode is forced to binary, so 'r' is the same as 'rb'. I removed the 'b' from the signature for clarity. ## Jan’s points not yet addressed: ## 3. I expect the built-in open() function would already be much more obvious and advertised, so I didn't add any cross-reference from codecs.open(). 5. Both points still need addressing: * Lack of requirement for implementing incremental codecs * Responsibility of implementing error handlers 9. First point left unaddressed: * register_error() error_handler replacement data type (unsure of details) ## Numbering Nick’s points: ## 12. Codec name normalization: Not addressed; what should be written? [13. Registration not reversible: Added in patch] [14. Added CodecInfo class, pulling out some existing details from register().] 15. “encodings” module: not done 16. Import system: not done ## My (Martin’s) point: ## [17. IncrementalEncoder.reset(): done] ## Zoinkity’s points, not addressed: ## 18. Multibyte codecs 19. register() usage example ## Some new points of my own that need fixing: ## 20. The doc string for register() says the search function is also allowed to return a tuple of functions, but the reference manual does not mention this. Which is more accurate? (I notice CodecInfo is a subclass of “tuple”.) 21. EncodedFile() seems to return StreamRecoder instances. Perhaps move them closer together? Should probably warn that EncodedFile's data_encoding is handled by a stateless codec. 22. The Codec.encode() and decode() methods return a length consumed, but I suspect they have to consume everything they are supplied because the code I have seen ignores this return value. -- keywords: +patch Added file: http://bugs.python.org/file37485/codecs-doc.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19548 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
