First, when you call isprime() on the last line, you have to pass a number to test to the function, and you have to receive the result. Then you want to print out the result. As far as error messages, while testing, put some print statements in the body of …

You can also use: [code]if score < 60: grade="F" elif score < 70: grade="D" elif score < 80: grade="C" elif score < 90: grade="B" elif score < 101: grade="A" else: print score, "is bogus"[/code]but as stated earlier, it depends on what makes sense to you. i.e. what the outline is. …

Code something up and try it for yourself. If you get an error message then post the code here for some help.

Also, you might subprocess instead. From the Python docs: "The subprocess module allows you to spawn new processes, connect to their input/output/error pipes, and obtain their return codes." [url]http://blog.doughellmann.com/2007/07/pymotw-subprocess.html[/url]

[QUOTE]How can I sort it by any columns?[/QUOTE]There is a way to do this using a function, but you will have to at least __try__ to do it yourself first and then post the code here. I hope you understand that it is considered rude to "place your code order" …

First off, Python doesn't really have arrays unless you include some of the add on packages. Python uses lists, so I would suggest that you take a look at lists. Combining is a simple matter. You can iterate through the lists with a for loop, creating a new list with …

set.Set has nothing named elems. Beyond that it is hard to say. Post a question to the author at ActiveState, or e-mail them directly if there is an address. Also, post some code with what it is you are trying to do so someone can come up with something that …

Look at the line following elif status == 0.3: And why do you have if/elif? Why not just print the value?

It would be better to use an existing tool like Metakit or SQLite. This pages show how it would be done with Metakit [url]http://www.equi4.com/metakit/python.html[/url]

[QUOTE=Ene Uran;439119]This is such an easy problem, I suggest you really try to understand it![/QUOTE] Also, a Google for "fibonacci python" has everything anyone could want. These posters are too lazy to ever make it as a programmer.

Try append instead of add. Any tutorial or on-line book can help you with lists and how to add/append items.

[quote=grahhh;429382]This is a simplification of what the data looks like (hundreds of lines like this): [two spaces]6.0730000e+003[tab][one space]-9.2027000e+004[tab][two spaces]7.8891354e+01[tab]\r\n[/quote]string.split() treats all whites space (space, tab, newline) the same s=" 6.0730000e+003\t -9.2027000e+004\t 7.8891354e+01\t\r\n" print s.split() ['6.0730000e+003', '-9.2027000e+004', '7.8891354e+01']

>>> a=b="test" >>> print a test >>> print b test >>> id(a) 3084724384L >>> id(b) 3084724384L Or convert the string to a list and then back to a string when you are finished.

It is easiest to write the data to a file, close it, and then call lpr using os.system() providing you want plain text. Anything more and you have to format it. Postscript is the easiest way to format output.

You might want to try [code] import string file_pointer= open('wordlist.txt', 'U') dictList = file_pointer.readlines() file_pointer.close() x = 0 newDict = '' stop = len(dictList) while x < stop: ## you could also use "for each_rec in dictList :" [/code]

[quote=Jergosh;307508]each plugin .py file is executed (via execfile()) by the PluginManager[/quote] I am not 100% sure what you are doing, but wouldn't you want the PluginManager to be an inherited class.

If you want to find file date, stats = os.stat( filename ) print time.ctime( stats[8] ) prints 'Tue Dec 26 14:28:16 2006' string.split, etc. yields the month, although I think you should also take the year into account.

If you just want to download, you can use wget with the --user and --password options with a frontend to call it at specific times. I don't know if that will solve the problem, but it does have a resume option, so you at least won't have to start over …

This will print your PYTHONPATH. If the path you want is not listed, and it shouldn't be because your program isn't found, then you have to use sys.path.append to add it.[code] import sys path_list= sys.path for eachPath in path_list : print eachPath[/code]

I like your solution, and I don't think there is any other way to handle the ace problem[quote]but was informed by one of my students that I put in a poker-like betting system instead of the blackjack betting system[/quote]They always know more than we do. Viva la future.

[quote=goms;302388] import win32API.client ImportError: No module named win32API.client[/quote]I use Linux, but I think you would want to import win32API, without '.client' although I'm not sure. If that fails, search for win32API on you system. It is likely that you have to append the path to PYTHONPATH using sys.path.append( some_path_name). EDIT: …

[quote]... one of the while loops has an eternally unfulfilled condition.[/quote] This is the only thing that could cause this problem (so of course it's something else). Add a separate counter to each while loop and exit after max cycles. [code]ctr_1 = 0 while True : ctr_1 += 1 if …
