[Tutor] 'sphere' object is unindexable

[Mr Gerard Kelly]

I am trying to get around the problem of sphere object being unindexable.

I need to make spheres appear, positioned according to some list, for
example:

for i in [0,1]:
  sphere(pos=(0,i,0), radius=0.1)
  

Is there any way of making these different spheres behave differently
without using indexing?

For example, I would like to be able to make the lower sphere go red
when it is clicked on, using this fragment of code:

while True:
  if scene.mouse.events:
m = scene.mouse.getevent()
if m.pick is ball[0]:
  ball[0].color = color.red

But obviously it won't work because I haven't named it ball[0]. I can't
figure out a way to name the objects based on their position without
using indexing. Is there any way to do this?

Thank you.

so for that i guess i would have to use ironpython and not Cpython which is
what i normally use . Are there any big problems porting the code from one
to other that i need to be worried about.

[Tutor] totally stumped on signal code, wont work in this instance

[dave selby]

Hi,

I have been hitting my head on a brick wall on a bit of code that
refuses to work. I have similar code in other scripts that works AOK
I have commented out all functionality except the core problem ...


import sys, threading, time, os.path, urllib, time, signal, ConfigParser, logger


def main():
#logger.log('daemon starting ...', 'CRIT')
#read_config()
#thread1 = Thread1_PTZ()
#thread1.setDaemon(True)
#thread1.start()
#thread2 = Thread2_PTZ_Park()
#thread2.setDaemon(True)
#thread2.start()
#thread3 = Thread3_PTZ_Preset()
#thread3.setDaemon(True)
#thread3.start()

while True: # sleep to keep daemons alive :)
time.sleep(60 * 60 * 24)


def signal_hup(signum, frame):
"""
SIGHUP, unlike all other daemons SIGHUP causes this daemon to exit killing
all its daemon threads. This is a workaround. Because 'kmotion_ptzd' is
threaded the only way to get the threads to reliably reload their config
is to kill and restart else they languish in a sleep state for ? secs.

args: discarded
excepts :
return  : none
"""

print 'sighup :)'
#logger.log('signal SIGHUP detected, shutting down due to
threading', 'CRIT')
#sys.exit()

...
main()

So main just sits there AOK. I send a sighup to the script with

pkill -SIGHUP -f python.+kmotion_ptzd.py

and I get ...

d...@main-system:~/kmotion2/core$ ./kmotion_ptzd.py
Hangup
d...@main-system:~/kmotion2/core$

OK so I would have expected signal_hup to have intercepted the signal
and printed 'sighup :)'
and also not have exited in this case.

Any ideas, I can solve most of my python probs but this one has me stumped.

Cheers

Dave

[Tutor] any best practice on how to glue tiny tools together

[Daniel]

Hi Tutors,

I want to use python to finish some routine data processing tasks
automatically (on Windows).

The main task could be split to sub small tasks. Each can be done by
executing some small tools like "awk" or by some other python scripts.
One example of such task is conducting a data processing job, including:

   1. use tool-A to produce some patterns.
   2. feed tool-B with these patterns to mine more related data
   3. repeat these tasks circularly until meeting some conditions.

The real task includes more tools which run in parallel or sequential
manner.

I know how to do this with modules like subprocess, but the final python
program looks somewhat messy and hard to adapt for changes.

Do you have any best practices on this?

Thanks a lot,
Danny

Re: [Tutor] Designing a Dialog in Python

[Alan Gauld]

"Wayne Watson"  wrote 

Signature.htmlWhen I used VBasic many years ago, 
it had the ability to design a dialog and then attach it 
to the code. Is there something like this available for Python?


What I think you are looking for is a GUI design tool.
There are several for Python, some commercial some free.
In my experience none of them are anywhere near as good 
as the VB or Delphi ones. However SPE worked, and I 
know some folks have gotten Glade to work.

I think dabo might work too.

And if you are on a Mac you can use the standard XCode 
development tools to build a GUI and connect Python 
via the PyObjC bridge.


The bigger issue is that all of these tools are tied to GUI 
frameworks so you need to learn how to program using 
the framework first. wxPython or PyQt seem to be the 
most popular for GUI bulders but a few have modified 
the underlying framework to produce their own dialect. 
(I think dabo is an example)


However most Python programmers still seem to build 
their GUIs using vanilla code rather than a visual editor.
If you don't  need the visual design tools then you can 
design dialogs etc in your favourite editor and for that 
Tkinter/Tix come as standard.


HTH,

Where is the indexing issue?
Are you trying to store the spheres in a list and index the list
to access a sphere or are you trying to use an index to access
some aspect of the sphere?

Show us the code that sdoesn't work and the error message.
Don't just describe it. Show us. Don't assume we know what
you are trying to do - we are not psychic.


For example, I would like to be able to make the lower sphere go red
when it is clicked on, using this fragment of code:

   m = scene.mouse.getevent()
   if m.pick is ball[0]:
 ball[0].color = color.red

But obviously it won't work because I haven't named it ball[0].


So why don't you name it ball? and what is m.pick supposed to be?
Some attribute of a muse event based on your code but I have
no idea what it might be!

A standard list should work and so provided you stored your
spheres in a list when you created them you should be able to
access them via an index. But without real code and a real
error trace we can't help very much other than by making
speculative guesses.

You do not need enumerate in that case:

offset = 3  # constant
my_input = "one two three four five six seven eight nine ten"
words = my_input.split()
for i in range(offset, len(words)-offset):
# beware of right-open range:
slice =  [word for word in words[i-offset : i+offset+1]]
print i,slice
==>
3 ['one', 'two', 'three', 'four', 'five', 'six', 'seven']
4 ['two', 'three', 'four', 'five', 'six', 'seven', 'eight']
5 ['three', 'four', 'five', 'six', 'seven', 'eight', 'nine']
6 ['four', 'five', 'six', 'seven', 'eight', 'nine', 'ten']

Adapt using a 'guard' based on offset's value if you actually want all lines.

Don't you have to register your handler with something like
signal.signal(signal.SIGHUP, signal_hup)
?

Thank you all for the great solutions. I'm really grateful, but also still
confused about indexing now. Why is it that if i = 0 indexing starts with
-3.  I never read this before, and I thus assume it is an advanced thing, or
why is it not in elementary to intermediate resources ( The ones I used at
least). Can somebody please suggest an accessible tutorial on this?

My first thought was, use shell pipelines and bash. Then I remembered,
David Beazley shows how to use generators to implement a processing
pipeline in Python:
http://www.dabeaz.com/generators-uk/

It's a fascinating read, it might take a couple of times to get it but
it might fit your needs quite well. You would write a generator that
wraps a subprocess call and use that to access external tools; other
pieces and the control logic would be in Python.

PyParallel seems buggy, even the install script has one and it has

[Tutor] improving the speed of prime number code

Hi,

I'm stuck with Problem 10 (

A part of my code deals with the calculation of prime numbers. However it is
really slow. Hopefully you have some ideas how to make it faster.

pz = [2]
# only iterate over odd numbers
for i in xrange(3,200,2):
  remprod = 1  # product of remainders
  for j in xrange(len(pz)):
remprod *= (i % pz[j])
if remprod == 0:  # if a number is divisible wo remainder its not prime
  break
  if remprod > 0:
pz.append(i)

Re: [Tutor] improving the speed of prime number code

[taserian]

One potential way to speed up is not to divide by every prime in your pz
list, but only up to the square root of i.

For example, to test if 37 is prime, you would only need to look at primes
less than or equal to int(sqrt(37)) = 6.08. . .

Not sure why you accumulate the products, just keep a flag or use an
else clause on the for loop.

for p in pz:

You inner loop could be (not tested)
for p in pz:
  if i % p == 0:
break
else:
  pz.append(i)

You might search the archives for more ideas, this is a popular
question. There is a very slick Python implementation of the Sieve of
Eratosthenes that uses slice assignment to mark off the non-primes.

Hi,

(http://projecteuler.net/index.php?section=problems&id=10 
) :-)


A part of my code deals with the calculation of prime numbers. However 
it is really slow. Hopefully you have some ideas how to make it faster.


pz = [2]
# only iterate over odd numbers
for i in xrange(3,200,2):
  remprod = 1  # product of remainders
  for j in xrange(len(pz)):
remprod *= (i % pz[j])
if remprod == 0:  # if a number is divisible wo remainder its not 
prime

  break
  if remprod > 0:
pz.append(i)
  
I know prime # algorithms have been discussed on at least one of the 
Python lists, and are also found in various internet resources.


Without consulting them let me offer:
- odd prime numbers are = 6x-1 or 6x+1 where x is integer.
   That reduces the # of candidates.
- the highest candidate you need to test is <= the square root of the 
candidate.

   That reduces cycles of the inner for loop
- there is no need to initialize remprod
- you can use "for j in pz:" to access successive pz's
   in which case you'd write i % j
- there is no need to multiply remprod by the remainders as you don't 
use that result later.

[Tutor] Closing and Open File--TkFileDialogs

[Wayne Watson]

Title: Signature.html




I'm using asksaveasfilename, and, as I understand it, it returns the
file name to me in write mode. I don't recall that there's a way to
reference the file with only the filename. That is, there's no
filename.write(). Comments?

While I'm at it, I have found a good example program for TkFileDialog
methods, but the description of them on the internet is pretty shallow.
For example, An Intro to Tkinter, Lundh's Tkinter pages, NM Tech pdf
files and Python docs have little to say.

OK, You lost me right here.

What is a reverse shell? That's a new one for me?
(I tried wikipedia but drew a blank)


I have a listening Python socket and I would like to know how I can
redirect the CMD prompt to stdin,


It might be useful to know what OS you are on and how you are
running this application. Also is the listening socket on the same
computer as the "reverse shell"?


can interact with the host that is sending the shell.


The fact you mention host suggests its a separate box, but I'm not 
sure.


Curious,

[Tutor] How to avoid error message: "_csv.Error: new-line character seen in unquoted field - do you need to open the file in universal-newline mode?"

[Judith Flores]

Hello,

   I get the error message above quite often when trying to open some csv 
files. I noticed that if I open the csv file in excel and delete the "empty" 
columns at the right end of my data, the error message doesn't appear.

My code looks like this:

myfile=open(csvfile)
reader=csv.reader(myfile)
header=reader.next()

Thank you,

Judith

Let me know if you would like to have some of my csv files.

I think you are confused between askopenfile() and askopenfilename().
The first opens the file and returns a file object, the second returns
just the file name and you open the file yourself.

Like Alan, I never heard of reverse shell before. With a little
googling I think I understand it but I don't understand your question.
Is the python program on the client (user) side or the server side?

Re: [Tutor] WINSOCK stdin question

[Tom Green]

The Python app is on the Server side. Sorry, I don't mean to cause hassle
for anyone.  I appreciate everyone's assistance.

I am trying to reproduce what Netcat does.

Thanks,
Mike

I'm aware of a visual design tool for Tkinter. I tried it (nowhere near as
polished as delphi/VB of course) for about 30 seconds before deciding I
didn't need the visual design tool. I forget what the editor was called
though >.< doh!

Of course you could always roll your own in Tkinter ;)

[Tutor] Picking up citations

[Dinesh B Vadhia]

Hi!  I want to process text that contains citations, in this case in legal 
documents, and pull-out each individual citation.  Here is a sample text:

text = "Page 500 Carter v. Jury Commission of Greene County, 396 U.S. 320, 90 
S.Ct. 518, 24 L.Ed.2d 549 (1970); Lathe Turner v. Fouche, 396 U.S. 346, 90 
S.Ct. 532, 24 L.Ed.2d 567 (1970); White v. Crook, 251 F.Supp. 401 (DCMD 
Ala.1966). Moreover, the Court has also recognized that the exclusion of a 
discernible class from jury service injures not only those defendants who 
belong to the excluded class, but other defendants as well, in that it destroys 
the possibility that the jury will reflect a representative cross section of 
the community. In John Doggone Williams v. Florida, 399 U.S. 78, 90 S.Ct. 1893, 
234, 26 L.Ed.2d 446 (1970), we sought to delineate some of the essential 
features of the jury that is guaranteed, in certain circumstances, by the Sixth 
Amendment. We concluded that it comprehends, inter alia, 'a fair possibility 
for obtaining a representative cross-section of the community.' 399 U.S., at 
100, 90 S.Ct., at 1906.9 Thus if the Sixth Amendment were applicable here, and 
petitioner were challenging a post-Duncan petit jury, he would clearly have 
standing to challenge the systematic exclusion of any identifiable group from 
jury service."

The results required are:

Carter v. Jury Commission of Greene County, 396 U.S. 320 (1970)
Carter v. Jury Commission of Greene County, 90 S.Ct. 518 (1970)
Carter v. Jury Commission of Greene County, 24 L.Ed.2d 549 (1970)

Lathe Turner v. Fouche, 396 U.S. 346 (1970)
Lathe Turner v. Fouche, 90 S.Ct. 532 (1970)
Lathe Turner v. Fouche, 24 L.Ed.2d 567 (1970)

White v. Crook, 251 F.Supp. 401 (DCMD Ala.1966)

John Doggone Williams v. Florida, 399 U.S. 78 (1970)
John Doggone Williams v. Florida, 90 S.Ct. 1893, 234 (1970)
John Doggone Williams v. Florida, 26 L.Ed.2d 446 (1970)

Before attempting to solve this problem I thought I'd first ask if anyone has 
seen a solution before?  

If not, I'll follow-up with some rules and an initial attempt.

Thanks

Dinesh
