You can use "lsof" (list open files) but that gives a huge amount of data since it will list any and all system files, etc. as well. [QUOTE]The application cannot generate any indication of completion of the process.[/QUOTE]Why not? That is the standard way of doing things. Processes are meant …

I didn't spend a lot of time on the code, but best move should be similiar to legal move. IMHO this should be implemented as a class. That would avoid the gobal variables and make the code cleaner. But you may not have gotten into creating classes yet. Also, the …

Doing this in memory is definitely the way to go. It could be 1000 times faster. Putting 17,000 records into memory is not a big deal in today's world. If each of the records is 100 bytes long, then you have 1,700,000 bytes. If your computer has 2 gig of …

[QUOTE] if you want to make a super amazingly quick program and it had to be in python then maybe this could even matter (i doubt it)[/QUOTE]I doubt it as well. I view the "function calls are expensive" as someone trying to impress with how much they know. Function calls …

[QUOTE]I thought old_leader was assigned in the constructor?[/QUOTE]Look again. You declared self.old_leader, so what is the difference in a class structure between self.old_leader and just old_leader.

Please post the error message to avoid this type of "looking for 'not in' as bad syntax when it is really a colon" errors. Same thing for "not in" is a bad descriptor. The error message probably has other info which possibly points to "never_save.readlines()" as the real problem.

"=" means they are equal, i.e. the same memory address, so when you change one, you change the memory that they both point to. You can instead use: a = [1,2,3] b = a[:] ## copy all of the elements in "a" to a new block of memory Also, there …

I think you are looking for subprocess.call() if you just want to run the program "tasklist.exe", instead of using "print". See here [url]http://blog.doughellmann.com/2007/07/pymotw-subprocess.html[/url]

I would suggest using lsusb, but this will list all usb devices, so if you have a printer or mouse, or possibly an sda drive, you will have to weed them out.

You could try cypes and convert via C, which should be a lot faster. Also note the surprising difference when using the decimal class below.[CODE]import decimal import datetime #**setup part** j = 0 myint = 1 while j < 100000: j = j + 1 myint = myint * 10 …

Please don't double post. Stick with one thread and mark the other "Closed" or "Solved". And a title like "someone please help!!!!!!!!!!" will get less responses not more. It does not state a specific problem and indicates someone who is looking for someone to write free programs for them. The …

Off-topic, how can I join the F-ugly code club? Whenever someone touts a program written in "pure python" I wonder if that means that my programs are in impure python. Maybe a support group would help: "Hello, my name is Joe and I write ugly code"

See the last post in this thread [url]http://www.daniweb.com/forums/thread210760.html[/url] It has links to reading files and online starter books for Python.

What is in entry_list, class instances? The simple solution is to create a list of lists with each sub-list containing [field_to_sort, class_instance] and just use the built in sort method. [QUOTE]sorted_ent_list = entry_list.sort(key=entry_T.get_word())[/QUOTE]If entry_list is a list of class instances, then you would have to use something like sorted_ent_list = …

You'll have to post the Tkinter part of the code. There is no root.mainloop() in the code you posted.

Computers are faster than serial ports, so you are probably getting several reads (and processing) the same data more than once, and reading and trying to process the null between each piece of data. For serial reads you want to do something like this pseudo code: [CODE]port_read = False data …

There is no difference, as far a calling a function goes, between calling a function within or without a program. The following works for me with the calc() function contained in the same program file.[CODE]from Tkinter import * def calc(one, two, result): def addition(): add = one + 1 print(add) …

It;s just personal preference, but I prefer multiprocessing to threading (If you are using Python2.5 or lower, then you will have to download pyprocessing and substitute "processing" for "multiprocessing" in the code below).

Run this piece of code and then take a look at where you can add some print statements to your code so you will know what is actually happening.[CODE]item = "third = 1" if item.find("third"): print "item found at position", item.find("third") else: print "item NOT found, value returned =", item.find("third") …

There are two problems while True: x=f.readlines() You read the entire file on every loop, so you willl always get the first rec of the newly read list. if not x: break x.next() This may exit if you have any blank lines in the file. Instead, you want to loop …

You should state what you are trying to accomplish and perhaps someone will help with that. We are not your personal answering machine. Please don't waste everyone's time.

You haven't recieved many answers, and probably won't because your examples are incomplete. You are obviously doing something in the code that is not posted that alters the result. Take a look at the following code that is a complete program that can be run. It shows that your contention …

Not that I know of. You would have to use a dictionary with the integer as a key, with the value being a counter integer that you would increment each time. There is a count function for lists that would return the number of times something occurs in a list, …

This is pretty straight forward and done quite often. It assumes, of course, that the file is already in a sorted order. First, declare an empty list to store the records in. Read the file one record at a time and extract the two fields you want to compare. If …
