 Hi friends

 help me with the following code. Im able to execute the code but getting 
 wrong output

 def sequence_b(N):
 N = 10
 result = 0
 for k in xrange (1,N):
 result  +=  ((-1) ** (k+1))/2*k-1
 print result
 print sequence_b(10)

 This is the output which im getting
 -1
 -4
 -5
 -10
 -11
 -18
 -19
 -28
 -29


 But i want output as
 1
 -1/3
 1/5
 -1/7
 1/9
 -1/11
 1/13
 -1/15
 1/17
 -1/19

You probably want this:

N = 10
result = 0
for k in range (1,N):
step = ((-1)**(k+1))/(2*k-1)
result += step
print(step)

Note: 
1. You don't use the parameter N, you immediately change it to 10. Leave the 
line N = 10 out.
2. Your function doesn't return its result, so it returns None. So the print 
sequence_b(10) dosn't make sense.
If the print is only for debugging the use the following:

def sequence_b(N):
result = 0
for k in range (1,N):
step = ((-1)**(k+1))/(2*k-1)
print(step) ## debug output
result += step
return result

print(sequence_b(10)) # print the result of the function call

[I use print() because I use Python 3]

20 Euro won't buy you much in the way of programmer time. Most job ads
I've seen are offering at least $50/hr for salaried work, and contract
work will start a lot higher than that. (I don't know how rates are in
Europe, but they'll be roughly in the same ball-park.) Your figure
would buy you maybe half an hour of someone's time... if you're lucky.
Most likely it's not even on anyone's radar. Perhaps now you'll have
some appreciation of how much you get *for nothing* here on this list.

The main point of my post, though, was that if you pay someone to do
your work for you, you WILL have to accept the way s/he does things.
If you get a guy to design you a database for your hit counter and he
does it with two tables, only a crass fool would then say I don't
care how well you've done that, I'm going to do it MY WAY instead,
because if you really knew better than the person you hired, you would
have done it yourself. (Incidentally, this is exactly why I am no
longer with my former employer. He didn't respect my designs, so now
he's free to do his own.) You need to be willing to accept advice once
you ask for it; otherwise, just do things yourself - and cope with the
legal requirements, which I don't think you've yet even considered,
despite spending all this time on tracking your users and retaining
personal/private information.

Go to your local library and pick up a book on database design - or
possibly you'll find it on Wikipedia. There ARE good reasons for the
hassle of normalization. There are times when you consciously
denormalize (I often read tables into memory for a (read-only) cache,
and denormalize aggressively), but the rule of thumb is: It's normal
to normalize.

First of all Nikos, you are not qualified to determine if there is
reason to design a database in any particular way, since you don't
understand what a relational database is.
Secondly, in earlier threads I provided you with a link to a wikipedia
article about first normal form and why it is a necessary component of
data base design.
If you don't want to use a database, good for you, but if you can't
get your website to work and you ask for help, then respond that the
help is 'too much hussle', you are disrespectful.
You don't bother me because you are lazy, and arogant, and whiny.  Or
that you lack skills.  You are a cargo cult programmer.  I know you
won't look that up.  You bother me because you are disrespectful.  The
most disrespectful person I have ever encountered on line.

On a side note to whoever hacks into Nick the idiots website -- why
not just take it down.  Then he won't have any need to spend his 20

Greece is no more represented by Nikos than any other nations are
represented by their ignorant.  When I start to feel ill-will towards
Greece because of Nikos, I also have to remember that the country has
also produced great technologists like Lea Verou and classical art 
philosophy.  Then I just wonder why Nikos doesn't take advantage of
the resources his home country provides. :-/

 Hi Anthony Papillion.
 
 I'm fresh to Python, but I do love its short simple and graceful.
 I've solved your problem. You could try the code below:
 
 getargfromcli.py \{'url':'http://www.google.com'}\
 
 AS command line will strip your .
 
 From the Python document, we could get the info as:
 json.loads('[foo, {bar:[baz, null, 1.0, 2]}]')
 the json.loads' argument should be string. Try it:)

That's not going to work, JSON strings must use double quotes, which you've 
rewritten as single quotes. The correct way (as shown previously) is to wrap 
the entire string in single quotes, thus preserving the double quotes inside.

splitting file/content into lines based on regex termination

2013-11-07 Thread bruce

hi.

got a test file with the sample content listed below:

the content is one long string, and needs to be split into separate lines

I'm thinking the pattern to split on should be a kind of regex like::
br#45 / 58#0#
or
br#9 / 58#0
but i have no idea how to make this happen!!

if i read the content into a buf - s

import re
dat = re.compile(what goes here??).split(s)

--i'm not sure what goes in the compile() to get the process to work..

thoughts/comments would be helpful.

thanks

Non-normalized data is sometimes a fine idea. How you plan to use
the data once it is stored will be the deciding factor.

One big win with databases is that you can query them really
easily using SQL. Non-normalized data negates that advantage.

How would you write a query to discover all the visitors who
downloaded file XYZ? With your storage scheme, you can't. So by
storing the data this way, you are promising yourself that you'll
never need to write that query, or at least, you won't need to do
it very often.

 I still don't know why you push me to create an extra table
 instead.

Because it's usually the right thing to do.

The split method also returns what's matched in any capture groups,
i.e. (\d+). Try omitting the parentheses:

dat = re.compile(rbr#\d+ / \d+#\d+#).split(s)

You should also be using raw string literals as above (r...). It
doesn't matter in this instance, but it might in others.

Accessing the Taskbar icons

2013-11-07 Thread Krishnan Shankar

Hi All,

I am automating an application in windows using python.

After installation i need to check if the applications icon has appeared in
Taskbar or not. If yes i need to right click the application.

I had been using pywinauto for the same but could not get the job done till
now.

I did the following,

app=pywinauto.application.Application()
hand=pywinauto.findwindows.find_windows(class='Shell_TrayWnd', title=u'')

When i use the handler, get the window and do a right click i am able to
click only in the taskbar and not icons. That maybe because i did not
recognise the icon yet.

Can you guide me how to do the same using pywinauto or pywin32?

Re: Show off your Python chops and compete with others

2013-11-07 Thread Nathaniel Sokoll-Ward

Wow! Thanks for all the feedback everyone. This content is fresh so I 
appreciate everyone's comments. As opposed to responding to each post 
individually, I'll just lump everything in here...

Andrew, big thanks for your comments:

 What is the correct number of spaces for indentation in Python? 

 I presume the question should be more along the lines of What does PEP8 
 say?, because all answers are correct. 

I agree. Question has been edited.


 String literals are written with what? 

 The answer is not ALl of these answers are correct 

I believe that string literals can be written with single, double, or triple 
quotes: http://docs.python.org/release/2.5.2/ref/strings.html

 Which is a correct way to perform exponentiation in Python? 

This was a silly error. Thanks for pointing it out.

 What does the following code do? 
 def a(b, c, d): pass 

 My answer: Defines a function which returns None, but that isn't one 
 of the choices. 

Roy, thanks for your note. When I run this code, the function just gets defined 
and nothing happens. None isn't returned. Do you recall why you found the 
options available to you unsuitable?

 How could you open a file c:\scores.dat to write in binary? 

 outfile = open(c:\\scores.dat, w) 
 outfile = open(c:\scores.dat, a) 
 outfile = open(c:\\scores.dat, w) 
 outfile = open(c:\\scores.dat, wb) 

 Not technically wrong, but stylistically suspect; I would recommend 
 using forward slashes (which work fine on Windows) and avoiding the 
 drive letter, both of which avoid making your example 
 Windows-specific. (At least, I don't think there are any other 
 platforms Python supports that use drive letters; OS/2 support was 
 dropped a little while ago, though I believe Paul Smedley still

Excellent suggestion. We've gone ahead and made the change.


 Which method will write a pickled representation of the object to 
 an open file? 

 Method names without object names aren't all that useful. Do you mean 
 Which method of the pickle module...? 

Again, great suggestion.

 
 From which languages are Python classes derived from? 

 Sounds like Python history trivia more than a coding challenge, but if 
 that's what you want to go for, sure. 

I agree it's not directly coding related. Our questions are actually sorted 
into topic buckets. We try to get a reading on people's knowledge in a bunch of 
different areas of a given skill. Familiarity with general knowledge facts such 
as this, gives us another data point to help parse out the types of questions 
the best developers tend to get right.

 By the way, here's a fairly bad solution to your final question: 

 array666=lambda x:b\6\6\6 in bytes(x) 

 Works for the given test-cases! Doesn't work with arrays at all, 
 despite the description. 

Chris, I actually really like your answer, even if it doesn't satisfy the goal 
in the question. I'd give it a vote for cleverness!

 You know, I didn't even notice that. But since that was copied and 
 pasted, I would say that yes, it really does. That's a pretty simple 
 grammatical bugfix though. 

Silly error. Fixed.

 I have to concur with what several other people are saying here.  Several of 
 MetaBright's questions are  ambiguously worded, or expect non-idiomatic 
 Python code.  It might be helpful for you to ask (hire?)  some seasoned 
 Python programmers to critique your questions. 

Thanks for the thoughts, John. I'd be lying if I said I wasn't disappointed 
with how many errors everyone here is picking out. Some of our Challenges are 
built exclusively by our users, others are built by someone who helped build 
MetaBright, while others, like the Python Challenge, are built with the help of 
contractors. Even so, the responsibility to make sure we are publishing high 
quality content falls on our shoulders and I regret we didn't go a better job 
of vetting this material. 

 With tracking cookies blocked, you get 0 points. 

 And with JavaScript blocked, you get bupkis. :-) 

I know that's frustrating. Our tech lead will be on here later today to explain 
why we do this.

Thanks again everyone!

Re: splitting file/content into lines based on regex termination

2013-11-07 Thread bruce

hi.

thanks for the reply.

tried what you suggested. what I see now, is that I print out the
lines, but not the regex data at all. my initial try, gave me the
line, and then the next items , followed by the next line, etc...

what I then tried, was to do a capture/findall of the regex, and
combine the outputs in separate loops, which will be ugly but will
work

  ff= byu2.dat
  #fff= sdsu2.dat
  with open(ff,r) as myfile:
s=myfile.read()


  s=s.replace(nbsp, )

  #with open(fff,w) as myfile2:
  #  myfile2.write(s)
#br#45 / 58#0#
#br#45 / 58#0#
  #dat1=re.compile(br#(\d+) / (\d+)#(\d+)#).search(s).findall()
  dat1=re.findall(br#(\d+) / (\d+)#(\d+)#,s)
  dat=re.compile(br#(\d+) / (\d+)#(\d+)#).split(s)
  dat2 = re.compile(rbr#\d+ / \d+#\d+#).split(s)
  #dat=re.split('(br#(\d+) / (\d+)#(\d+)#)',s)
  #dat=re.compile(br#(\d+)).split(s)


  for m in dat:
if m:
  print m = +m

  #sys.exit()

  print dat1
  print dat1
  print len(dat1)
  print dat2a
  #sys.exit()

#  for m in dat1:
#if m:
#  print m = +m
#
#  #sys.exit()

  for m in dat2:
if m:
  print m = +m

  #sys.exit()

  sys.exit()

  return


the test data is pasted to -- http://bpaste.net/show/kYzBUIfhc5023phOVmcu/

 so i'd have the results of the compile/regex process to be added to
 the split lines

 thanks

 The split method also returns what's matched in any capture groups,
 i.e. (\d+). Try omitting the parentheses:

 dat = re.compile(rbr#\d+ / \d+#\d+#).split(s)

 You should also be using raw string literals as above (r...). It
 doesn't matter in this instance, but it might in others.

Re: Algorithm that makes maximum compression of completly diffused data.

2013-11-07 Thread Mark Janssen

Well let me try to explain why it is working and i have implemented one.
I only need to refresh my memory it was almost 15 years ago.
This is not the solution but this is why it is working.
65536=256^2=16^4=***4^8***=2^16

 All of those values are indeed the same, and yet that is completely
 unrelated to compression.  Did you honestly believe this was actually
 explaining anything?

I think the idea is that you could take any arbitrary input sequence,
view it as a large number, and then find what exponential equation can
produce that result.  The equation becomes the compression.

We do not currently support cookieless or javascript-less browsing. We are 
definitely looking at relying less and less on cookies, but it's unlikely we'll 
ever be able to pull out javascript as it limits interactivity too much. Its 
definitely possible to do, and maybe something we can look at in the future, 
but right now we don't have the resources for that. Sorry for the inconvenience!

It was mostly in jest as it's one of the things I test when doing
web development.  That said, the quizzes are mostly just HTML forms
where you pick the answer with a radio button and click the [next]

Additionally, I noticed that if I accidentally select an answer

Not so polite, since in one arbitrary record into my clients db he 
placed the entry Stupid Coder, Stupid Site.


But i'm happy that s/he cannot mess again with my databases.

I feel a bit proud because as it seems i have manages to secure it more 
tight. All i need to do was to validate user input data, so the hacker 
won't be able again to pass bogus values to specific variables that my 
script was using.


Prove me otherwise mighty one if i'm mistaken!

Interesting idea, but I don't see how this has anything to do with
compressing arbitrary data. We already have a compact notation for
representing a large number as 2^24*x+2^16*y+2^8*z+q, so I don't see

 Wow! Thanks for all the feedback everyone. This content is fresh so I 
 appreciate everyone's comments. As opposed to responding to each post 
 individually, I'll just lump everything in here...

Best way, I think :)

 I believe that string literals can be written with single, double, or triple 
 quotes: http://docs.python.org/release/2.5.2/ref/strings.html

Hmm. As a general rule, can you consider aiming your quiz - and any
citations like this - at a current version of Python? I'd prefer to
see this sort of thing aimed at the 3.3 docs, though if you want to
cite 2.7 that would also be of value. But 2.5 is now quite old, and
I'd rather not get the impression that you're writing a quiz based on
an unsupported version of Python. :) Though in this particular
instance it makes no difference.

 By the way, here's a fairly bad solution to your final question:

 array666=lambda x:b\6\6\6 in bytes(x)

 Works for the given test-cases! Doesn't work with arrays at all,
 despite the description.

 Chris, I actually really like your answer, even if it doesn't satisfy the 
 goal in the question. I'd give it a vote for cleverness!

Heh. Do you know what the limitation of my solution is, though? As I
said, it works for the given test-cases; what sort of input will it
fail on? (And also: What's its algorithmic complexity, and what's the
complexity of a better solution?) That's why I said it's a bad
solution :)

The side comment about arrays, though: Python *does* have arrays, but
they're a different beast from what you're working with, which are
called lists. The version I posted will actually work with any
iterable, but specifying that it be a list might open up some other
options.

BTW, you're going to see a lot of criticism on the list, because
that's the natural state of things. Doesn't mean we didn't enjoy
taking the quiz. :)

In your Intermediate section:
Which of the following is false regarding the raw_input() and
input() built-in functions in Python?

The old raw_input() has been renamed to input() in Python 3.x
input() is equivalent to exec(raw_input())
In Python 2.x, raw_input() returns a string.
raw_input() does not exist in Python 3.x

Technically one of those is false, but (a) you really need to specify
versions a LOT more clearly here, and (b) the falseness is a minor
technicality; it took me a while to notice that you'd written exec
where it actually uses eval. Is that distinction really worth
highlighting in the quiz?

Which of the following statements is false?

Python can be used to generate dynamic web pages.
Python can be used for web development.
Python's syntax is much like PHP.
Python can run on any type of platform.

What does *any type* of platform mean? Do you mean any platform, and
if so, do you mean that there is no pocket calculator on which Python
doesn't run? Or is there some other type of platform?

 type(platform)
class 'module'

I get it. Python will run on any module. *dives for cover*

BTW, here's my chosen bad solution for the boss question at the end
of the intermediate section. I'm sure someone here can come up with a
worse one. Wasn't sure what should be done if all three numbers are
the same, incidentally.

def indie_three(*numbers):
seen = {}
tot = 0
for n in numbers:
seen.setdefault(n, 5)
seen[n] -= 4
tot += n * seen[n]
return tot

Note how I've generalized it to any number of input values AND to any
possible number of duplicates!

It was necessary post post web server's logs by doing
tail -f '/usr/local/apache/logs/error_log'

so to display the error message i got.

Also i never claimed i was a professional coder, i am an amateur at a 
beginner level and i do it out of hobby.


I could have designed my website in a CMS( wordpress, joomla) but i like 
programming and wanted to design and learn to code at the same time.


Since i'm an idiot as you call me try to hack it yourself since you are 
so smart.


And i don;t think it was an sql injection by the way.
It was just a manipulation of the 'page' variable my script is using.
Hacker was able to pass bogus info to that variable.

I believe he passed values to var 'page' via URL like

http://superhost.gr/?page='

make money - that is, that you either get a salary for it or you have

 Neither do shifting goalposts.

It's not a shifting goalpost.  My original statement was that:

def foo():
   raise Exception

defines a function which 1) has no explicit return statement and 2) does 
not return None.  I stand by that statement.  There is no possible 
codepath, no possible calling sequence, no possible execution 
environment, which will cause that function to return None.  That fact 
that one particular Python implementation happens to produce unreachable 
bytecode for returning None is meaningless.  Would you say that:

def baz():
   return None
   print I got here

is a function which prints I got here?

Technically, the universe could expand temporarily or reconfigure to
allow it; the question is who or what will have to shift out to allow
it?

Granted, but I would describe this:

def foo(x):
return Hello, world!\n + str(x)

as a function which returns a string. Is it? Well, not if str raises
an exception. Even if the only arguments you can give to foo will
result in exceptions, I would still say that, per design, this is a
function that returns a string. The possibility of raising an
exception (and thus not returning anything) doesn't change a
function's return type (by which I mean more than just what C would
use as the declaration - I could just as well say Returns the name of
an employee, and the same argument would apply).

... okay, I bow to your superior power. If you can make the very
*UNIVERSE* bow to your compression algorithm, I have to admit defeat.

Please, you are he obnoxious, so fuck off or go learn about reformulation of 
problems. Every number has an infinite number of arithmetical solutions. So 
every number do has a shortest arithmetical encoding. And that is not the hard 
part to figure out, the hard part is to find a generic arithmetic encoding.

I am not sure if it is just stupidness or laziness that prevent you from seeing 
that 4^8=65536.
