move up a level

[rplobue@yahoo.com]

alright, noob question: i want to open a file in a directory above the
current one i'm in. I'm trying to use myfile =
open('../thefileiwant.tx t', 'r') but the ../ doesn't work. How do i
do it?

that's how it's usually done. what does "doesn't work" mean in this case?

"Doesn't work" means what?
Have you looked at the getcwd and chdir functions in the os module?
You may wish to check that os.getcwd()'s notion of "current directory"
is the same as yours.
If you can't make any progress, ask again; do copy and paste the
relevant parts of your script instead of trying to describe what you
did. Also copy and paste output. Hint: use temporary print statements
to show what is happening.

HTH,

Above the process' current dir, or above the dir where the script resides?
You get the latter with os.path.abspath (__file__)

Hello, I proved your doubt in my PC and it works fine. This is the example:

Python 2.4.4c1 (#2, Oct 11 2006, 21:51:02)
[GCC 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)] on linux2
Type "help", "copyright" , "credits" or "license" for more information.

>>import os
>>os.getcwd()

'/home/manuel/descargas'

>>file = open('../proof.py')
>>print file.read()

import sys
if __name__ == '__main__':
print 'manuel'

>>>
