Dynamic programming worked for me in Python, I am not sure how efficient you can make your recursive algorithm, probably need memoized function to approach dynamic programming approach. Looks like you want to find the length of the common sequence only.

[QUOTE]This is useful for example when a program needs to pass a new filename to a function which does not accept a file object argument. [/QUOTE] You can also pass .name of the file object but then you should close the file by hand before function reopens it from the …

You are having unnecessary closing of quotes and plusses: [CODE]import urllib City="%D9%85%D9%87%D8%B1%D8%A7%D9%86" Province="%D8%A7%DB%8C%D9%84%D8%A7%D9%85" myurl = 'http://www.owghat.com/owghat.png.aspx?Province=%s&City=%s'%(Province, City) #the real address is:http://www.owghat.com/owghat.png.aspx?Province=%D8%A7%DB%8C%D9%84%D8%A7%D9%85&City=%D9%85%D9%87%D8%B1%D8%A7%D9%86 a="e:\\img.png" urllib.urlretrieve(myurl,a) [/CODE] Your string seems not valid for utf-8: [CODE]>>> u'مهران'.encode('utf-8') Unsupported characters in input [/CODE] Otherwise you could do like this: [CODE]>>> c = u'Hölmö hämäläinen'.encode('utf-8') >>> …

You mean letter of highest frequency? I think sorting by counting and finding the maximum is equivalent problem if you are not dealing with unicode.

At least type import lower case as python is case sensitive.

You can not find corresponding element from other list by min2. Use this corresponding relation: [CODE]corresponding(A, B, [A|_], [B|_]). corresponding(A, B, [_|C], [_|D]) :- corresponding(A, B, C, D). [/CODE] [CODE]| ?- corresponding(X, 3, [a, b, c], [5, 3, 6]). X = b ? a no | ?- [/CODE]

You would need to install chilkat module [url]http://www.chilkatsoft.com/python.asp[/url] for your python version and use the code: [url]http://www.example-code.com/python/zip_AppendRenamed.asp[/url]

OpenCV could be nice place to start, as I understand it has webcam support and supports various programming languages and operating system. [url]http://opencv.willowgarage.com/wiki/[/url]

How about simple "qwerty.txt", without path, shouldn't it mean the same? What error message are you getting? You should check the return value in variable userfile for the error.

For me [URL="http://www.cherrypy.org/"]cherrypy [/URL]looks most nice to program with, of course there is plenty of alternatives and Django is quite popular like also Pylons and Turbogears.

Are you following the forum? I just posted yesterday one counter program without using modules: [url]http://www.daniweb.com/software-development/python/code/373760[/url]

Do not reinvent the wheel, use codecs module: [url]http://www.doughellmann.com/PyMOTW/codecs/[/url] (non-unicode stuff is at the end part of the post)

You have doubled lines 3 and 4. There is max 8 characters read from file with no null termination, then you try to pass it as char parameter to function exe (which should not work), to try to print the letter. I do not get it. You are not trying …

timer_update -> if Paused do nothing else put to label current_time - paused_time - start_time Pause pushed -> if in Paused state add current_time - pause_start_time to paused_time else save current_time to pause_start_time. Why you are used capitalized object names (like Reset) for methods? If you have not any super …

This does not look very efficient with transponation, sort and transponation back, so I am happy to hear about better alternatives.

Another task from C++ forum is trivial in Python even taking handicap of not using Counter.

With such restrictions given and with speed of current computers as it is, I would say that you just do it simply, primitively and fast enough (I do know more C than C++): [LIST=1] [*]Do struct with 3 letter id and count for enough numbers [*]From first number step forward …

Which webserver are you using?

My not OO version of timer for work and pause time (but it does use attributes for functions, which are objects, to avoid global declarations in functions).

You have much dublication of code, which makes your code difficult to maintain. Please refactor. Your choice of user interface is also not to my liking, I would prefer interface with add and modify buttons and grid in ranking order for any number of girls with their own names instead …

Do not use goto and functions like part2, mathematics is never called and you have repeated same lines instead of using a function (refactor to function).

You could use up counting for to increment the stop condition of inner loop and manage with two nested fors.

What is wrong with set, if order need not be preserved: [CODE]>>> x = [2,3,1,3,5,4,5] >>> print([2*a for a in set(x)]) [2, 4, 6, 8, 10] >>> [/CODE]

numpy histogram function looks close to your needs, it is designed for using with Python language though, probably written with C though and source code is open source. [url]http://amusecode.org/doc/examples/simple/salpeter.html[/url] Maybe worth to hunt through C++ libraries for histogramming?

Also it is generally better idea to keep information together. So you would have one info list with [[name, age], [othername, otherage] ....] Your reading file by bytekinds is un-ideomatic, as I understand you have fixed lenght line of 20 for name and 2 for age. I would say like …

-?location(california, X) Your output looks not possible as you have no tany stamp in your DB.

Line 40 has no purpose. You are replacing the function find_session_id with slice at line 41, what is purpose of that? You have read [url]http://docs.python.org/library/email-examples.html[/url], haven't you?

To retain the value you should prepare copy of the list, if deep copy is not needed, you can do it with slicing (otherwise use copy module) [CODE]>>> a=[{'a':1,},{'b':2,}] >>> b = a >>> b.pop(0) {'a': 1} >>> a [{'b': 2}] >>> b [{'b': 2}] >>> a=[{'a':1,},{'b':2,}] >>> b=a[:] >>> …
