Script can't find input file despite being in the same directory

[Robocop]

I have a simple little script that reads in postscript code, appends
it, then writes it to a new postscript file. Everything worked fine a
month ago, but after rearranging my directory tree a bit my script
fails to find the base postscript file.

The line in question is:

for line in fileinput.input (['base.ps']):
output.write(li ne)

I'm kind of at a loss as the script is executing in the same directory
as base.ps, yet it can't find it. I'm relatively new to python
scripting, so i'm expecting it's just something i haven't learned
about python that is causing the problem. Any suggestions would be
greatly appreciated.

What directory is output if you insert the lines:

from os import getcwd
print "CWD:", getcwd()

just before the line is question?

Cheers,

Put this before the line that fails and see what it tells you:
print os.getcwd()


getcwd = get current working directory

The output is /home/bruce/DEVadhc/attendance

which is the directory i expected, and the directory that contains
base.ps

You can get the directory of the script with this useful snipplet:

import os
HERE = os.path.dirname (os.path.dirnam e(__file__))
PS_FILE = os.path.join(HE RE, "base.ps")

I'm kind of an idiot, i just realized the problem. Sorry for wasting
your time, and thanks for the help!
