hi all,
what's the simplest way to create a webpage with a frame for Python
code to be typed in (as a plain text, or, better, as a highlighted
text or something like scite or any other easy python IDE, capable of
automatic indentations), and then pressing a button to evaluate it
using a remote serv

Hi all,
I would like to introduce a couple examples of easy & convenient
modelling and solving System of Linear Equation (SLE) by FuncDesigner
(a python-written tool, BSD license). It doesn't require to construct
matrices A and b (Ax = b) by user, they are created automatically. See

Hi all,
I'm glad to inform you about new release of our free (BSD-licensed)
soft OpenOpt 0.28 (numerical optimization), FuncDesigner 0.18 (CAS

differeces derivatives approximation).

Hi all,
I'm glad to inform you about new quarterly OpenOpt/FuncDesigner
release (0.32):
OpenOpt:
* New class: LCP (and related solver)
* New QP solver: qlcp

* New large-scale NSP (nonsmooth) solver gsubg. Currently it still
requires lots of improvements (especially for cons
hi all,
I have th PEP (I'm not sure something like that hadn't been proposed
although):
very often in a Python file header the following lines are present,
like:

import MyModule2 as mm2
from MyModule3 import myFunc3 as mf3
etc
and after several pages of code they are
Yes, I know, still usually it is placed in file header

Also, result of

hi all,
I have a class (FuncDesigner oofun) that has no attribute "size", but
it is overloaded in __getattr__, so if someone invokes
"myObject.size", it is generated (as another oofun) and connected to
myObject as attribute.
So, when I invoke in other code part "hasattr(myObject, 'size')",
instead

hi all,
what is easiest way to check python version (to obtain values like
2.4, 2.5, 2.6, 3.0 etc) from Python env?
I don't mean "python -V" from command prompt.
Thank you in advance, D.

So, are there any ways to change operator precedence (for my class)?
To Diez:
yes, but I haven't paid attention to xor. BTW the url is currently
unavailable (Network Timeout. The server at docs.python.org is taking
too long to respond.).

which method should I use to get iterator over (key, value) pairs for
Python dict, Python v 2.6 and above?
Of course I could use

value = myDict.values()
# do something with the pair key, value
but searching each time for the value take some cputime that
Yes, thank you, items() is the correct approach, on the other hand I

Hi all,
could you inform me how to do it properly?
I have the cycle
for i in xrange(len(Funcs2)): # Funcs2 is Python dict
Funcs.append(lambda *args, **kwargs: (Funcs2[i](*args, **kwargs)
[IndDict[left_arr_indexes[i]]]))
So, all the Funcs are initialized with i = last index = len(Funcs2)

Thanks all, especially Dennis for your detailed answer.
left_arr_indexes is list of nonnegative integers, eg [0,0,0,1,1,4]
IndDict is a dict like {0: [1,2], 3: [0,1], 10:[0,2,3]}, so that's why
I don't use python list instead.
The code is taken from OpenOpt framework that I develop. Currently I

hi all,
I have the following problem:
I have overloaded "max" function in my module (FuncDesigner); it works
like following:
if some data in arguments is of type "oofun" then my function works,
elseware numpy.max() is used.
Now the problem:
suppose someone writes

I need to create a Python list of lambda-funcs that are dependent on

F.append(lambda x: x + i)

So what's the best way to make it val
