Indeed, THERE IS a removeHandler() method. In the documentation of 
python 2.6, it is mentioned in '16.6.5. Logger Objects', directly after 
the addHandler() method. If you found the addHandler() method there, you 
should have found removeHandler() too.

And a simple

>>> dir(log)
['__doc__', '__init__', '__module__', '_log', 'addFilter', 'addHandler', 
'callHandlers', 'critical', 'debug', 'disabled', 'error', 'exception', 
'fatal', 'filter', 'filters', 'findCaller', 'getEffectiveLevel', 
'handle', 'handlers', 'info', 'isEnabledFor', 'level', 'log', 
'makeRecord', 'manager', 'name', 'parent', 'propagate', 'removeFilter', 
'removeHandler', 'root', 'setLevel', 'warn', 'warning']

also would have revealed it to you.

What about this:

>>> for handler in log.handlers:
... log.removeHandler(handler)

I think, that's just one of the tasks that removeHandler() was written 
for.

One of the best ways would be to read the documentation. And to do some 
exploration, e.g. by means of dir() and help(), could also be quite 
instructive. This experience cannot be replaced by 
documentation-research requests to the Usenet.

I'm sure Tim was aware of the removeHandler function. But this is
still reaching into log.handlers - although IMO it's safer to reach in
and read than to reach in and mutate. So without the implications of
Tim's inability to read docs, this is a viable suggestion. I'd prefer
this over the original "del log.handlers[:]".

Hm, what do the docs say about this one?

>>> import logging
>>> logging.basicConfig()
>>> log = logging.getLogger("foo")
>>> for i in range(5):
... log.addHandler(logging.FileHandler("tmp.log"))
... 
>>> assert len(log.handlers) == 5
>>> for handler in log.handlers:
... log.removeHandler(handler)
... 
>>> log.handlers

I'm not an expert on your code, and I have very little idea what that is 
supposed to do. Judging by the name "getnumline", my first guess is that 
the function takes a line number n, and it will return the nth line of 
some source:

getnumline(source, 5)
=> returns the 5th line from source

But that's not how you use it. You pass it a "file". Is that a file 
object, or a file name? My guess is that it would be a file object, since 
if you wanted a file name you would have written getnumline(filename). Is 
that a file object that is open for reading or writing? I'd have to guess 
that it's open for reading, since you're (probably?) "getting" from the 
file rather than "putting".

So... something like this:

file = open("some thing")
for line in getnumline(file):
...

Presumably it iterates over the lines of the file, but what it does with 
the lines is hard to say. If I had to guess, I'd say... maybe it's 
extracting the lines that start with a line number? Something like this 
perhaps?

def getnumline(file_object):
count = 0  # Or start at 1?
while True:
line = file_object.readline()
if line == '':
break
if line.startswith(str(count)):
yield line
count += 1

But this is only a guess, based on the assumption that while the function 
name is misleading, it's not *entirely* misleading. I'm puzzled why the 
function claims to do something with "line" singular, when you're 
obviously using it to iterate over lines plural.

Contrast that with an example from the Python built-ins: enumerate. What 
you get is exactly what it says on the tin: the function is called 
enumerate, and enumerate is what it does:


enumerate
v 1: specify individually; "She enumerated the many obstacles
 she had encountered"; "The doctor recited the list of
 possible side effects of the drug" [syn: enumerate,
 recite, itemize, itemise]
2: determine the number or amount of; "Can you count the books
   on your shelf?"; "Count your change" [syn: count, number,
   enumerate, numerate]

Yes, I'm aware of it, having read the source & docs.  However, the
signature is

  removeHandler(some_handle_to_a_handler_that_you_already_have)

and at the point in my code where I need to override this,
basicConfig() has already assigned a default stream handler and
discarded the handle/name/reference to it because
the .debug/.info/.warn/.error/.critical methods of all call
basicConfig() if there aren't any handlers.

[Aside: which is non-pythonically, using "if len(self.handlers) == 0"
instead of "if not self.handlers" in addition to the camel-case
naming (which would be much harder to fix)]

> >>> for handler in log.handlers:

The question revolves mostly around dipping your hands into the
undocumented .handlers property.  I can nuke it directly (and looking
at least at the 2.7 source, there doesn't seem to be much issue with
doing this), or I can iterate (as modified by Chris Angelico to
prevent modifying the list over which you're iterating). Either way,
it still involves reaching into log.handlers which doesn't appear in
any of the documentation as far as I could find.

So yes, I use help() and dir() on a daily basis.  But just because
something is there doesn't mean I should go mucking with it in the
event it's undocumented.  If it *should* be trusted as a publicly
available interface, it should be documented; if it shouldn't be
treated publicly, then it should have a way to iterate over them
such as

  def iterHandlers(self):
for h in self.handlers[:]:
  yield h

so you can do

  for h in log.iterHandlers():
log.removeHandler(h)

Given how stable this code has been over the years, I'd just document
the log.handlers property and possibly advise to lock around messing
with it (unless "del log.handlers[:]" is atomic).

Thread is somehow interfering with a while loop called after the thread is started

[Dan McInerney]

Coming back to this a long time later. I figured it out a little bit after
I posted this. I wasn't aware that q.try_run() within the nfqueue module
was a blocking call
https://www.wzdftpd.net/redmine/projects/nfqueue-bindings/wiki/Examples.
I'm not sure I was even aware of what it meant to be blocking vs
nonblocking. Either way, someone from #python looked at my code and told me
nfqueue is a blocking call and I should look into something like twisted.

Twisted is a complex module but I spent a bunch of time looking at it and
eventually had some working code implementing the absolute bare essentials
as I needed them to go asynchronous. This question eventually progressed
into https://github.com/DanMcInerney/LANs.py.

Speaking of network concurrency, my recent project has been from a web
scraper point of view and I think gevents+requests or gevents+mechanize are
the way to go for that somewhat-related topic. erequests won't import due
to a bug, grequests has no way to handle exceptions in the fetching of
responses, treq can't find and fill out form logins (maybe with a POST,
haven't explored that route), and scrapy is way too big and complex for my
latest project (https://github.com/DanMcInerney/shodan_pharmer), eventlets
I'm sure CAN work with libraries other than urllib2 but it implements and
imports its own urllib2 and it is not a favorable time:effort ratio for me
to try and implement that.

Installing addition libraries in Portable Python 2.7 on Windows

[laguna-mc]

I am new in Python, I have Portable Python 2.7.5.1 installed on Windows 7.

I want to install additional libraries:

python-magic
libmagic
libfuzzy
pyqtgraph

I downloaded package, saved on hard drive, unzipped, find setup.py and tried 
install via Command Prompt:

Python-Portable.exe setup.py install

A new DOS terminal window briefly flashes and disappears, without showing any 
error or installation confirmation.
I assume that nothing has been installed and/or installation failed.. No tips 
or errors has been shown, so I don't' know how to install these packages 
corretcly.
I tried also to install get-pip.py use same way, and again nothing happens, no

IIRC you need to obtain ez_setup.py to get easy_install and only then 
will get-pip.py work.

Sorry, your original article lacks information about what you already

Heh, I tried to make that clear in my initial posting with the "since
there are other methods for adding/removing handlers" bit.  I guess I
could have been more explicit though as to what I'd tried.  I
generally figure that, if someone knows enough to dig into the
stdlib's source code, they also know enough to use dir() and help().
Not *always* the case, but a good hint that they're past the basics.

But I could have clarified my question more along the lines of
"Should log.handlers be public/documented; should Logger grow
clearHandlers() and iterHandlers() methods; or should I wantonly use
log.handlers but then just get to keep both pieces if/when it breaks?"

Judging by the name, I'd say that "matplotlib-1.3.1.win32-py2.7.exe" is

Did you have something to say about this? Perhaps a question, with
details of what you're expecting and what happened instead?

First: please don't top-post; Instead, use the normal interleaved
posting style to make it easier to follow the conversation
https://en.wikipedia.org/wiki/Posting_style#Interleaved_style>.

Second: I don't have any idea what you're referring to, and your
messages give no explanation. Is this a question about Python, or some
specific tool, or some library, or what?

What are you trying to do (and please say it in terms that means we can
try to reproduce the problem), and what are you seeing instead, and how
does that differ from what you expect?

[Larry Hastings]

On behalf of the Python development team, I'm thrilled to announce
the official release of Python 3.4.


Python 3.4 includes a range of improvements of the 3.x series, including
hundreds of small improvements and bug fixes.  Major new features and
changes in the 3.4 release series include:

* PEP 428, a "pathlib" module providing object-oriented filesystem paths
* PEP 435, a standardized "enum" module
* PEP 436, a build enhancement that will help generate introspection
   information for builtins
* PEP 442, improved semantics for object finalization
* PEP 443, adding single-dispatch generic functions to the standard library
* PEP 445, a new C API for implementing custom memory allocators
* PEP 446, changing file descriptors to not be inherited by default
   in subprocesses
* PEP 450, a new "statistics" module
* PEP 451, standardizing module metadata for Python's module import system
* PEP 453, a bundled installer for the *pip* package manager
* PEP 454, a new "tracemalloc" module for tracing Python memory allocations
* PEP 456, a new hash algorithm for Python strings and binary data
* PEP 3154, a new and improved protocol for pickled objects
* PEP 3156, a new "asyncio" module, a new framework for asynchronous I/O

1) You've already been asked not to top-post. Please, read the
Wikipedia page Ben linked you to.

2) If you put no effort into your question, why should we put effort
into the answer?

3) You're asking about a particular program. Unless you can show that
the problem you're having is specific to Python, you'll probably do
better to ask the author of that program. Look around and see if s/he
has a recommended means of getting assistance - maybe a mailing list.

4) You still haven't explained your problem at all. While we might be
flattered at the implication that our skills are so great that we're
psychic, we're more likely to be frustrated by the utter lack of
information.

Please read this: http://www.catb.org/~esr/faqs/smart-questions.html
