Why about you just ignore me? Serious, a lot of people here seem to think that if someone is bothered by someone else, the bothered person should just ignore the botherer. That is until something starts bothering these people themselves, then suddenly all kind of arguments are let loose in the hope of influencing the person that bothered them in changing his behaviour. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list

If you want to call it use this : def identity(func): @init def gen(func): x = (yield) while True: x = (yield func(x)) return gen(func).send Now you will get: >>> @identity >>> def f(a): a+1 ... >>> f(0) 1 Best regards, Marcin -- http://mail.python.org/mailman/listinfo/python-list

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:
http://docs.python.org/3/library/os.html#os.strerror
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:

Cheers,
Thank you, the error have been caused due to the fact that the uploading
procedure of my edited 'pelatologio.py' hadn't been completed yet, while
i was requesting the execution of the script via browser.
I didn't had to do anything it solved by itself, after upload was
successful and file got unlocked for access.
Thanks Cameron, and indeed the error message as you printed the Unicode
characters was saying in Greek that file was in use.

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

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:

Point well-taken. So I'll see what I can do here. I'll put comments on
lines I had to add or change.
finale_line = []#missing initialization
lot_number = 99
number_drawn=()
def load(lot_number,number_drawn):

line_out=line_out+(number_drawn)
print line_out
finale_line.append(line_out)
#finale_line2=finale_line #not referenced
load(lot_number,number_drawn)
print finale_line
print(" "*4),

space_count=int(a[b])
else:
pass
#print(" "*(a[b]-space_count)),a[b], #dead code
#space_count=a[b]+1#dead code
Since all the numbers are butted together in the string line_out, the
later logic is iterating over digits, which cannot be bigger than 9. So
the else clause is nonsensical. Even if they were to run, they'd give
runtime errors.

No clue what that means. What numbers are between what lines? And what
is a normal print?
Presumably the intent was to somehow do a variable spacing of those digits.

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:

No it hasn't. Nikos is a fraction of this list, and over the past while has shrunk far below his peak. The people spewing insults (including Nikos, but he's said he'll stop and I respect him for that) are a much more voluminous sect of this list and a much bigger problem. > In short if you agree and expand on only the first part of my request > >> - No discussions about Nikos specifically or trolling/flaming in general I don't care whether people "discuss" Nikos.

That's it. If you're insulted, tough. Take it off-list. If you think it's totally and unabashedly Nikos's fault, tough. Take it off-list. If you think Nikos is completely innocent, tough.

Oh, cruel. But you can do worse. Who needs "while" when you have
filter(iter(FUNCTION, object()))?
def get_name():
name = input("Enter your name: ")
return [
lambda: name,
lambda: print("No name longer than 20 letters."),
][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(
methodcaller("__call__"),
map(
partial(
getitem,
[
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.")
""")

I don't have anything to add to the discussion beyond restating what I've already said (which I'm not interested in doing), except to address this point in light of recent posts on the list. You claim "collective experience" is not reliable and dismiss it in favor of your own theory, flaming trolls is a better response. And your evidence for that? Nothing (that I've read so far). Collective experience may not always be totally reliable but it seems to me it is better than the non-experience that you have offered. 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. I, and I think the majority of people here, find that very unpleasant.

I've often thought it was redundant for Python to support 'if'
when it has dictionaries, cf the rationale for having no

Indeed it is not your intention to troll, you only want to ask questions. And if it turns out that your behaviour during the asking of these questions is very annoying, we should just shoulder the burden of that annoyance since it wasn't intended. Asking you to change your behaviour? That wouldn't be fair because you never intended to annoy. > Especially i cant stand people which never to spend 5 mins to reply, > but they are devoted a couple of weeks to belittle me instead.

Presumably, he has received criticism > for this (mostly on tone grounds, I imagine), either on or off list. That would be me, and it wasn't about Google Groups. After Mark was repeatedly abusive towards somebody, including telling this person to kill themselves, and after he chose to ignore both polite requests to cease flaming, and a fair warning that he would be kill-filed if he persisted, he persisted and so I kill-filed him. Which is a pity, because Mark does know Python well and he can be very helpful (although sometimes abrasive). I think on balance, when he's not flaming, he makes a positive contribution to this community. The kill-filing is only temporary, and I look forward to seeing his posts again soon. Hopefully by that time, he'll stop feeling put-out and hurt that I've chosen to not read his flames, and cease misrepresenting my actions. -- Steven -- http://mail.python.org/mailman/listinfo/python-list

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.

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
script to pick a particular directory for it to run in.

Since the filename of regression_2.py in the traceback is fully-qualified, I
expect that you are running the program from something other than the

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.

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
>>> 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
Python 3.x:
>>> import builtins
>>> 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
>>> builtins.open = open
>>> open
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

You can try to frame what you did as an innocent newbie asking questions but that is not what happened. What happened is that you started a project on which other people relied that was way over your head. That makes you more than just a newbie that makes you incompetent. When you then started to get into trouble you didn't just ask questions, you almost demanded that people would fix your problems for you, bumping a thread within a few hours if you didn't get an answer within that time. That and similar behaviour makes you a jerk. > > You on the other hand never care to reply to any of my questions(so it > was in someway justified for you to say i didn't follow your advice), > but instead you seem to be willing to judge endlessly for the help i > receive from others.

If you don't want this to fester, you'd better stop denying that you were behaving like an incompetent inconsiderate jerk. People can forget and forgive jerky behaviour but they don't tend to when they see the other denying he was behaving like a jerk. Because they then expect more of that kind of behaviour. > So shut your piehole and start proving yourself useful in this list. > Or sod off. > Preferably do the latter.

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
password protect file
