As much as you are right, this argument was started by Mark. If you reprimand anyone (other threads being ignored) it should be him. Reacting only to Nick, even though what Nick said was undue, implies that you agree with Mark's actions. I don't agree Mark started this argument. That he gave a negative appraisal of Nikos is not starting an argument in itself. Remember that Nick is as much a human as all of us, he is bound to have his feelings hurt when so many people pick on him -- whether they are justified or not. So? Should we particularly care about Nikos's feelings? Nikos is not the victim, he is the instigator. And should his feelings get hurt when it is pointed out what picture people got from him through his own behaviour, I say good.

On Sat, 29 Jun 2013 23:46:12 -0600, Ian Kelly wrote: On a related note, I think that generator functions should in some way be explicitly marked as such in the declaration, rather than needing to scan the entire function body for a yield statement to determine whether it's a generator or not. That was considered when generators were introduced in Python 2.2. Guido's rationale for preferring to keep def for both generator functions and normal functions is given in the PEP: Issue: Introduce another new keyword (say, gen or generator) in place of def, or otherwise alter the syntax, to distinguish generator-functions from non-generator functions. Con: In practice (how you think about them), generators *are* functions, but with the twist that they're resumable. The mechanics of how they're set up is a comparatively minor technical issue, and introducing a new keyword would unhelpfully overemphasize the mechanics of how generators get started (a vital but tiny part of a generator's life). Pro: In reality (how you think about them), generator-functions are actually factory functions that produce generator-iterators as if by magic. In this respect they're radically different from non-generator functions, acting more like a constructor than a function, so reusing def is at best confusing. A yield statement buried in the body is not enough warning that the semantics are so different. BDFL: def it stays. No argument on either side is totally convincing, so I have consulted my language designer's intuition. It tells me that the syntax proposed in the PEP is exactly right - not too hot, not too cold. But, like the Oracle at Delphi in Greek mythology, it doesn't tell me why, so I don't have a rebuttal for the arguments against the PEP syntax. The best I can come up with (apart from agreeing with the rebuttals ... already made) is FUD. If this had been part of the language from day one, I very much doubt it would have made Andrew Kuchling's Python Warts page. http://www.python.org/dev/peps/pep-0255/ 5+ versions later, I think that Guido has been shown to be correct. Even if you believe that generator functions would have been better with different syntax, there is no evidence that re-using def is actively harmful. -- Steven -- http://mail.python.org/mailman/listinfo/python-list

Re: settrace doesn't trace builtin functions
I've been using the settrace function to write a tracer for my program,
which is working great except that it doesn't seem to work for built-in
functions, like open('filename.txt'). This doesn't seem to be documented, so
I'm not sure if I'm doing something wrong or that's the expected behavior.
I believe that's expected behavior. Stuff written in Python is
traced. C functions are not. It's been a whole lot of years since I
looked at that code though, so I might be misremembering.
The other option I considered was monkey-patching the open function through a
wrapper ... but that seemed very brittle to me.
For debugging purposes, practicality beats purity. I trust you won't
be tracing in a production environment, so fragility shouldn't be a
major concern. Monkey patching seems entirely appropriate to me.
Python 2.x:
open
built-in function open
import __builtin__
open is __builtin__.open
True
_open = __builtin__.open
def open(name, mode=None, buffering=None):
... return _open(name, mode, buffering)
...
__builtin__.open = open
open is __builtin__.open
True
open
function open at 0x82afa3c
Python 3.x:
import builtins
open
built-in function open
open is builtins.open
True
_open = builtins.open
def open(file, mode='r', buffering=-1, encoding=None,
... errors=None, newline=None, closefd=True, opener=None):
... return _open(file, mode, buffering, encoding, errors, newline,
closefd, opener)
...
_open
built-in function open
builtins.open = open
open
function open at 0x1010c18c8
You can, of course, do this for more builtins. Presuming you can get
a handle on a function's namespace and modify it, you should be able
to perform the same trick for most functions or methods written in C.
sys._settrace = sys.settrace
def settrace(*args, **kwds):
... return sys._settrace(*args, **kwds)
...
sys.settrace = sys._settrace
Totally untested. No warranties expressed or implied. YMMV... etc, etc

How are you running the code? If you are doing pandas.read_csv('train.csv'), the
file must be in the current working directory of the running process. The
location of the .py file contain the code is not relevant. For example, if you
are using an IDE to run the script, you may need to configure how it runs the

Since the filename of regression_2.py in the traceback is fully-qualified, I

I thought the location of .py file and data file should be same. Thanks! Es. Robert Kern. Python didn't make that assumption, the author of the script did. By using a relative name like train.csv, he is implicitly forcing Python to use the current working directory. If he had wanted the file to be found in the same directory as one of the source files, he could have built an absolute path by using the __file__ attribute of the module. However, for non-const files, the source directory is generally a bad place to put them. Confounding things is the strange habit that Windows has of deciding that the script location *should* be your current directory. I believe Explorer does that if you right-click select a script. -- DaveA -- http://mail.python.org/mailman/listinfo/python-list

You are going to pretend it is just me and ignore all those others who made remarks about particular behaviour of you being annoying and unacceptable. I gave a specific answer, you bumping threads are only a few hours. You could have acknowledge that indeed you have been doing that and that you understand that it is annoying to others and you could have made it clear you intended to be more patient in the future. That could have been the beginning of you gaining again some good will from members of the group. Instead you chose to be a jerk about it. Pretending that the multiple remarks you have received about this behaviour didn't happen. Maybe you should change your perception of understanding things. Why should I. From the people with whom I discussed your behaviour, a lot disputed you were a troll, but none disputed you were behaving like an asshole. Yes even those who were willing to further help you agreed that your behaviour was problematic. I dont expect anyone to solve my problems, iam happy if they point me to a direction which i can solve it myself, that what the list is about. Sure, you just play the impatient jerk, who bumps threads and asks the same question again after people have pointed you in a direction. Did i told you to fuck off? Well never mind. Fuck off!

Ironically your flame war with Nikos in http://mail.python.org/pipermail/python-list/2013-June/650905.html provides evidence for the validity of the collective experience you dismiss, that engaging in flame wars with trolls simply produces more flames, hostility begets hostility.

And that is at least in part happening because of the wrong use of tools -- wrong uses that you are advocating above. To wit: 1. Kill-filing/spam-filtering are tools for spam. Nikos is certainly not spamming in the sense of automated sending out of cooked mail to zillions of recipients/lists. His posts are definite and intentional 2. Likewise Nikos is not trolling. A troll is someone who posts seemingly innocuous stuff to cause irritation and then enjoys the results. Here he clearly wants answers to the questions he is asking So I suggest that if we want to address this problem we need to sit back individually and collectively, put aside habitual labels like spam/troll, and likewise habits of mind, and ask what exactly is the problem we are dealing with. It feels good to see that some people in this list understand that i all i wanted was to only receive helpful replies, because i was and still am a newbie at Python and it was not a trolling act as falsely considered.. -- What is now proved was at first only imagined! -- http://mail.python.org/mailman/listinfo/python-list

PYTHONPATH and module names
So today, I created a file called 'formatter.py', and my program broke. It turned out that I was also import 'gluon' from web2py, which in turn, somewhere, imported the regular python formatter.py with which I was not familiar. So the question is: Does one simply always have to be knowledgeable about existing python library names, or is having '.' in the python path just a bad idea? Is there a way, not having '.' in the path to explicitly specify the current directory? Something analogous to import ./foo ? Thanks, Tobiah -- http://mail.python.org/mailman/listinfo/python-list

Oh, cruel. But you can do worse. Who needs while when you have

][len(name) 20]()
name = next(filter(None, iter(get_name, object(
But who needs *any* of this! Defining functions is so old-hat. It's
all already in the standard library (using only assignments and
function-calls):
from functools import partial
from operator import getitem, ge, methodcaller
from itertools import compress, tee
apply = methodcaller(__call__)
ret_true = partial(getitem, [True], 0)
print_invalid = partial(print, No name longer than 20 letters.)
inputs = iter(partial(input, Enter your name: ), ...)
inputs, valid = tee(inputs)
valid = map(len, valid)
valid = map(partial(ge, 20), valid)
side_effect_valid = map(partial(getitem, [print_invalid, ret_true]), valid)
side_effect_valid = map(apply, side_effect_valid)
valid_inputs = compress(inputs, side_effect_valid)
name = next(valid_inputs)
Which can be neatly expressed as two statements (I'm struggling to
got it to one without those evil lambdas):
from functools import partial
from operator import getitem, ge, methodcaller
from itertools import compress, tee
inputs, valid = tee(iter(partial(input, Enter your name: ), ...))
name = next(
compress(
inputs,
map(

map(
partial(

[
partial(print, No name longer than 20 letters.),
partial(getitem, [True], 0)
]
),
map(
partial(ge, 20),
map(len, valid)
)
)
)
)
)
Beautiful, see?
Of course, the most powerful function deals with this much more quickly:
exec(
while True:
name = input(Enter your name: )
if len(name) = 20:
break
else:
print(No name longer than 20 letters.)
)

Here is another example which I came across when playing with
generators, the first function is actually quite useful, the second
generator is the whole fun:
from functools import wraps
def init(func):
decorator which initialises the generator
@wraps(func)
def inner(*args, **kwargs):
g = func(*args, **kwargs)
g.send(None)
return g
return inner
@init
def gen(func):
x = (yield)
while True:
x = (yield func(x))
now if you have function f
def f(arg):
return arg**2
then calling f(5) is the same as
g = gen(f)
g.send(5)
I wrote a blog post where I did include this as a `useless` example:

You've included the same set of code twice. Also, it doesn't run as is,
so you haven't reduced it to a minimal working example for us to test.
Python's print adds a space where there's a comma, try this at the
interactive prompt:
print 'a','b'
a b
I don't think you're taking this into account. There are quite a few
other problems with your code, though:
number_drawn=()
def load(lot_number,number_drawn):
You've assigned `number_drawn` to a tuple, which is an immutable type.
Within the `load` function you then do:
number_drawn=raw_input(number: )
Which just re-assigns `number_drawn` to the output of the `raw_input`
function _within the function itself_. The value isn't available
outside of the function, if that is what you're intending. You also
haven't defined `lot_number` in your code, and again you re-assign it
within the body of the `load` function:
for lot_number in range(first,last):
Which has no impact on any global definition. Since you're not actually
passing values into the function you can probably do without both
arguments and just go with:
def load():
first=input(enter first lot: )
last=input(enter last lot: )
You should never use `input`, it evaluates the expression entered.
Always use `raw_input` unless you absolutely know what you're doing.
for lot_number in range(first,last):
`range` will start at `first` and finish _at but not including `last`.
If you want 4 lines when you enter first=1 and last=4, then you need to
increment `last` by 1:
for lot_number in range(first,last+1):
finale_line.append(line_out)
Where is `finale_line` defined? You haven't shown it but my guess is
you've made it an empty list. You're also not returning anything from
the function, which implies you're relying on global scope to hold the
result. This is bad practice. You should start your function with:
finale_line = []
And then end it with:
return finale_line
Which would allow you to replace:
finale_line2=finale_line
load(lot_number,number_drawn)
With:
finale_line = load()
for a in finale_line:
print\n,
print a[0], ,
space_count=1
for b in range(1,5):
This condition will _always_ be true:
if int(a[b])10:
Because of the way you're stepping through `finale_line`, you're only
ever looking at a single character, so that value will always be from 0
to 9. You clearly want to allow for double digit numbers, so not storing
them all as a big string would be a good start. You're dealing
with numbers, so hold them as numbers in a list.
Here's a more flexible approach that I think does what you want:
import os
def load_numbers():
first=int(raw_input(enter first lot: ))
last=int(raw_input(enter last lot: ))
finale_line = []
for lot_number in range(first,last+1):
line_out = []
for count in range(1,5):
number_drawn=raw_input(lot %d, number %d: %
(lot_number, count))
line_out.append(number_drawn)
finale_line.append((lot_number, line_out))
return finale_line
finale_line = load_numbers()
# get space needed from the maximum number entered
largest_number = max(
number for row,numbers in finale_line for number in numbers)
space_count = len(str(largest_number))
# get no. of columns from the first set of numbers
columns = len(finale_line[0][1])
# space to cover the lot numbers
print ' ',
# print the columns
for column in xrange(1, columns+1):
spacing = space_count - len(str(column))
print '%s%d' % (' '*spacing, column),
for lot, numbers in finale_line:
print os.linesep, # use the EOL used by the current
# operating system
print lot,
for number in numbers:
spacing = space_count - len(str(number))
print '%s%d' % (' '*spacing, number),
However, if you want to make your life a _lot_ easier when printing
tabular data, I highly recommend using a library dedicated to just
that, something like:

Errno 26 depends on your operating system. See man 2 intro for details.
But on my Mac and on a handle Linux system number 26 is:
26 ETXTBSY Text file busy. The new process was a pure procedure (shared
text) file which was open for writing by another process, or
while the pure procedure file was being executed an open call
requested write access.
See the os.strerror function for printing the message from an errno number:

I'd say you're trying to write to a file you shouldn't be writing to.
Maybe an executable?
Try to get your script to print out the filename of whatever it was trying to
overwrite before the open() call.
Regarding the characters, I'd say they've been double escaped. Let's undo that:

Others do a better job I am told -- and without being champs :-) That's not really valid, your proposed technique is use nothing, in which case using a wrench is a golden opportunity. And you've also implied that filtering out what you don't want is akin to hammering screws into bricks, in which case I've been programming wrong my whole programming life. Tools can be used right... and wrong. Sufficiently extreme wrong use adds to the original problem/mess. Kill-filing is a solution for one problem. In the current context it is much more the problem than the solution. Two cases: True, kill-filing *is* a solution for one problem. Don't get ahead of yourself, though, by assuming that implies it's not a solution for anything else. 1. My estimate is that about 30-40 *different* answers-ers in hundreds of different posts have expressed frustration with dealing with Nikos. The fact that they are now silent can mean one of two cases: I'm struggling to make those numbers add up. a. Nikos has turned a new leaf and become a golden boy b. The protesters have opted out of the discussion/system (like so-called democracies where 20% of the populace vote and criminals come to power) First of all, the basis on which you claim there are only two cases is false. Hence this point is void. Secondly: wut? How is any of this a relevant point in the least? You can take your pick on which case (Hint: Read this thread) 2. I am killfiling you is bullying behavior. It is worse than useless because No it is not. You can check the definition of bully if you want. Please try not to overuse emotionally rigged terms. a. The problem cases couldn't care a hoot Nikos has shown that he does, in fact, care a hoot. b. Those who could contribute usefully are shut up You wouldn't killfire someone whose posts you want to read. c. The messengers are being shot as substitute for the culprits If what the messengers are talking unacceptably for your tastes, then by all means you should have right not to listen. Is that not just basic reasoning? People aren't kill-firing because the messengers are telling truths we don't want to hear. People are kill-firing because they're doing it in ways that we don't find acceptable. On the whole we techies have a penchant (may I say allure?) for solving problems technically rather than socially. It works well up to a point: Thou shall indent thy programs is a social requirement in C and technical in python. And so we consider -- rightly -- that python advances C. However this line cannot solve all problems. Our belief that technology can solve all problems is directly linked to the impending fact that the planet may go up in smoke. Wut? In short technology in its place is good but conscience is not substitutable: the use of (tools like) kill-filing analogizes to this piece of medical logic: Brain tumor causes headache Aspirin cures headache Therefore aspirin cures brain tumors I see no connection. No connection to what this is supposedly an in short of (despite being longer) and no connection to the actual point you are trying to make. Basically, I don't understand what you're trying to portray. tl;dr Nikos is not spamming/trolling/baiting/flaming. The Nikos-threads are a more serious disease than all these. The fact that this thread is not started by him suggests the disease is spreading. By not speaking up one is colluding. You might want to look up colluding. Basically, rusi, I don't understand you. You seem to speak coherently, but I never know what point you are making, what side you are arguing. You seem to be strongly anti-Nikos, but further than that is opaque to me. What I'm not too fond of, though, is your seeming insistence that your methodology should be rigorously followed by every other party on this list -- we are not a dictatorship, least of all one of your control. As long as we all act civil, and occasionally on-topic, what you do is at your discretion. Plus it's hard to follow someone's command if you haven't the least idea what they're telling you to do. Actually, the one other thing I get from you is that you have the militant view of we have to all act now in unison to do whatever your goal is, still not sure. It might explain your odd choice of links. -- http://mail.python.org/mailman/listinfo/python-list

I am trying to create a regular expression that will return true for only
these tables:
MY_TABLE
YOUR_TABLE
I tried these:
pattern = re.compile(r_(?!(CTL|DEL|RUN)))
pattern = re.compile(r\w+(?!(CTL|DEL|RUN)))
pattern = re.compile(r(?!(CTL|DEL|RUN)$))
But, both match.
I do not need to capture anything.
For some reason I don't seem to have a copy of your initial post.
The reason that regex works is because you're anchoring it at the
start of the string and then telling it to match only if
.*(CTL|DEL|RUN) /doesn't/ match. That pattern does match starting
from the beginning of the string, so the pattern as a whole does not
match.
The reason that the other three do not work is because the forward
assertions are not properly anchored. The first one can match the
first underscore in MY_TABLE_CTL instead of the second, and then the
next three characters are TAB, not any of the verboten strings, so
it matches. The second one matches any substring of MY_TABLE_CTL
that isn't followed by CTL. So it will just match the entire string
MY_TABLE_CTL, and the rest of the string is then empty, so does not
match any of those three strings, so it too gets accepted. The third
one simply matches an empty string that isn't followed by one of those
three, so it will just match at the very start of the string and see
that the next three characters meet the forward assertion.
Now, all that said, are you sure you actually need a regular
expression for this? It seems to me that you're overcomplicating
things. Since you don't need to capture anything, your need can be
met more simply with:
if not table_name.endswith(('_CTL', '_DEL', '_RUN')):
# Do whatever

[issue16468] argparse only supports iterable choices
paul j3 added the comment: chris.jerdonek wrote: Also, to answer a previous question, the three places in which the choices string is used are: in the usage string (separator=','), in the help string when expanding %(choices)s (separator=', '), and in the error message text (separator=', ' with repr() instead of str()). In the usage string, the ',' is used to make a compact representation of the choices. The ', ' separator is used in the help line, where space isn't as tight. This 'choices formatting' is called during 'add_argument()' simply as a side effect of checking for valid parameters, especially 'nargs' (that it, is an integer or an acceptable string). Previously 'nargs' errors were not caught until 'parse_args' was used. This is discussed in http://bugs.python.org/issue9849 Argparse needs better error handling for nargs http://bugs.python.org/issue16970 argparse: bad nargs value raises misleading message On the issue of what error type to raise, my understanding is that 'ArgumentError' is the preferred choice when it affects a particular argument. parse_args() nearly always raises an ArgumentError. Once add_argument has created an action, it too can raise an ArgumentError. ArgumentError provides a standard way of identifying which action is giving the problem. While testing 'metavar=range(0,20)', I discovered that the usage formatter strips off parenthesis. A regex expression that removes excess 'mutually exclusive group' notation is responsible for this. The simple fix is to modify the regex so it distinguishes between ' (...)' and 'range(...)'. I intend to create a new issue for this, since it affects any metavar the includes (). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16468 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18334] type(name, bases, dict) does not call metaclass' __prepare__ attribute
Nick Coghlan added the comment: Unfortunately, it's not that simple, as calling type(name, bases, namespace) is *exactly* what a subclass will do as part of creating the type object. From inside the type implementation, we can't tell the difference between properly called from the child type and improperly called without preparing the namespace first. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18334 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
