How To Do It Faster?!?
by andrea_gavana＠tin.it March 31, 2005

March 31, 2005

Hello max & NG, >I don't quite understand what your program is doing. The user=a[18::20] >looks really fragile/specific to a directory to me. I corrected it to user=a[18::5][:-2], it was my mistake. However, that command is NOT specific to a particular directory. You can try to whatever directory or net resource mounted on your system. It works. >>> a=os.popen("dir /s /q /-c /a-d " + root).read().splitlines() Mhm... have you tried this command on a BIG directory? On your C: drive for example? I had to kill Python after having issued that command because it ate up all my CPU (1GB) for a quite long time. There simply are too many files/information to retrieve in a single command. In my first mail, I said I have to work with a BIG directory (more than 1 TB) and I need to retrieve information when they become available (I put this info on a wxPython ListCtrl). This is why I have chosen os.walk() and that command (that runs on a separate thread wrt the ListCtrl). It does NOT run faster than your command (probably my solution is slower), but I can get information on every directory I scan, while with your command I have to wait a long time to process the results, plus the user can not interact with the results already found. >To get a list containing files owned by a specific user, do something like: >>> files=[line.split()[-1] for line in a if owner in line] I will try this solution also. Thanks NG for your useful suggestions. Andrea.

problem running the cgi module
by chris patton March 31, 2005

March 31, 2005

Hi everyone. I'm trying to code an HTML file on my computer to make it work with the cgi module. For some reason I can't get it running. This is my HTML script: ------------------------------------------------------ <form method="post" action="C:\chris_on_c\hacking\formprinter.py"> <b><i><font size="50">HOWDY!</font></b></i><br><br> <input type="text" name="name" size="50" value=""><br><br> <input type="submit" name="send" value="submit"> </form> ------------------------------------------------------ And here is the python program it's supposed to run with, formprinter.py: ------------------------------------------------------ import cgi, cgitb cgitb.enable() form = cgi.FieldStorage() print '<font size="12">%s</font><br>' % form['name'] ------------------------------------------------------ Whenever I press submit on the HTML document, it returns the code for "formprinter.py". Can someone tell me what I'm doing wrong? -Thanks for any help!

Re: hiding a frame in tkinter
by Harlin Seritt March 31, 2005

March 31, 2005

faramarz, Most likely, you'll need to replace the 'forgotten' frame with another one or other widget. You can immediately do *.pack() and it will replace the frame (assumming you haven't already packed something else there). Harlin Seritt

split an iteration
by Robin Becker March 31, 2005

March 31, 2005

This function from texlib in oedipus.sf.net is a real cpu hog and I determined to see if it could be optimized. def add_active_node(self, active_nodes, node): """Add a node to the active node list. The node is added so that the list of active nodes is always sorted by line number, and so that the set of (position, line, fitness_class) tuples has no repeated values. """ index = 0 # Find the first index at which the active node's line number # is equal to or greater than the line for 'node'. This gives # us the insertion point. while (index < len(active_nodes) and active_nodes[index].line < node.line): index = index + 1 insert_index = index # Check if there's a node with the same line number and # position and fitness. This lets us ensure that the list of # active nodes always has unique (line, position, fitness) # values. while (index < len(active_nodes) and active_nodes[index].line == node.line): if (active_nodes[index].fitness_class == node.fitness_class and active_nodes[index].position == node.position): # A match, so just return without adding the node return index = index + 1 active_nodes.insert(insert_index, node) I determined that len was being called a large number of times so did a first rewrite as (minus comments) def add_active_node(self, active_nodes, node): index = 0 nan = len(active_nodes) node_line = node.line node_fitness_class = node.fitness_class node_position = node.position while index < nan and active_nodes[index].line<node_line: index += 1 insert_index = index while index<nan and active_nodes[index].line==node_line: if (active_nodes[index].fitness_class==node_fitness_class and active_nodes[index].position==node_position): return index += 1 active_nodes.insert(insert_index, node) which gives a good speedup even so I decided to eliminate the index += 1 in the first while loop which results in def add_active_node(self, active_nodes, node): nan = len(active_nodes) node_line = node.line node_fitness_class = node.fitness_class node_position = node.position insert_index = nan for index, a in enumerate(active_nodes): if a.line>=node_line: insert_index = index break index = insert_index while index<nan and active_nodes[index].line==node_line: if (active_nodes[index].fitness_class==node_fitness_class and active_nodes[index].position==node_position): return index += 1 active_nodes.insert(insert_index, node) and this change also results in a significant speedup and is I believe is still equivalent. I'm not sure exactly why this is faster than the while loop, but it is. However, it seems harder to get the same speedup for the last while loop; that loop is probably not such a problem so it's not terribly important. Is there a fast way to get enumerate to operate over a slice of an iterable? -- Robin Becker

It makes no sense having urllib generating exceptions for such a case. From its point of view, things work pefectly - it got a result. No network error or whatsoever. Its your application that is not happy with the result - but it has to figure that out by itself. You could for instance try and see what kind of result you got using the unix file command - it will tell you that you received a html file, not a deb. Or check the mimetype returned - its text/html in the error case of yours, and most probably something like application/octet-stream otherwise. Regards, Diez

Re: Generating RTF with Python
by Axel Straschil March 31, 2005

March 31, 2005

Hello! > does anyone know of a high-level solution to produce RTF from Python=20 > (something similar to > Reportlab for producing PDF)? Spend hours of googeling and searching, also in this NG, about two months ago. My conclusion is: On windwos, maybe you can include some hacks with dll's, under linux, linux support for generating rtf is none, and so is python's. My workaround was: http://www.research.att.com/sw/download/ This includes an html2rtf converter, which I access from python via popen and temporary files. Not high-level, not very sexy ... ;-( Lg, AXEL. -- "Aber naja, ich bin eher der Forentyp." Wolfibolfi's outing in http://www.informatik-forum.at/showpost.php?p=206342&postcount=10
