[Tutor] any help with this piece of code
import os fileList = [] subDirectories = [] directories = [] directoryPath = raw_input( Type in the path you want to start at: ) for directory,subDirectory, files in os.walk( directoryPath ): directories.append( directory ) subDirectories.append( subDirectory ) fileList.append( files ) for Files in fileList: print Files # It works fine up until here fileToSearchFor = raw_input( Type in the file name you want to search for: ) if fileToSearchFor in fileList: print %s was found % fileToSearchFor else: print %s was not found % fileToSearchFor Could someone explain to me why this pice of code doesn't work, in that it works fine up until where I have commented , but when I come to search the list for a file name, even though I know the filename is in that particular directory, and is present in the list returned by 'fileList.append( files )' it always reports that the file is not found. Incidentally if you try this code out, when prompted for the path to start at, don't select a large directory as it takes sometime to run. It may not be very useful I am just curious as to why the file name cannot be found in the list, what am I missing?

Re: [Tutor] sys.argv[1: ] help
Hi, Thanks a lot to everyone that replied. I was missing the %* in the following line, in the File associations I just had upto the %1. Adding %* cured my problem. Python.File=C:\Python24\python.exe %1 %* Sorry for the typos in some of my examples, every keyboard I've tried appears to have the same fault on it! Anyway thanks a lot again, Richard G. Smith, Jeff wrote: Richard, I have no problems running your example. It would be helpful in the future ot let us know which version and variant of Python you are running. I am using the canonical (as oppose to ActiveState) Python 2.4. From the command prompt, type assoc .py and you should see .py=Python.File Then type ftype Python.File which should return Python.File=C:\Python24\python.exe %1 %* If the last one isn't correct (with approriate path and assoc type associations) then you can correct it with ftype ASSOCTYPE=PATHSTUFF As an added bonus, you can also create a system environment variable called PATHEXT and set it to .py and you won't even have to type the .py to execute the script. I added all the following to my PATHEXT: .py;.pyw;.pys;.pyo;.pyc While you're at it, you should also check the assoc/ftype for .pyw as .pyw=Python.NoConFile Python.NoConFile=C:\Python24\pythonw.exe %1 %* Good luck, Jeff -Original Message- From: Richard gelling [mailto:[EMAIL PROTECTED] Sent: Sunday, February 27, 2005 1:41 PM To: tutor@python.org Subject: Re: [Tutor] sys.argv[1: ] help Hi, It is actually associated with just 'python', changed it to associate with 'pythonw' and I got nothing on the same example not even the [], so I am assuming that 'python' is the correct one?

The program: ## import sys print sys[1:] ## should raise a TypeError because 'sys' is a module, and not a list of elements, and modules don't support slicing. Just out of curiosity, can you confirm that you aren't getting an error message? (I know I'm being a bit silly about asking about what looks like a simple email typo, but computer programming bugs are all-too-often about typos. *grin* When you write about a program, try using cut-and-paste to ensure that the program that you're running is the same as the program you're showing us.)
