The OS module is great at this. Here's an example:

import os

MYFILE= '../../myfile'

print "MYFILE", MYFILE

print "abspath", os.path.abspath(MYFILE)


And, here is the output:

prompt> python example01.py

MYFILE ../../myfile

abspath /Users/glenjarvis/Desktop/test/myfile

You can also glean just the current working directory:

import os

print "pwd", os.getcwd()


And it's output:

prompt> python example02.py

pwd /Users/glenjarvis/Desktop/test/x/y


Cheers,
