Finding the relative path of a file from a dir

[Suresh Jeevanandam]

Hi,
a = '/home/suresh/doc/html/a1/'
b = '/home/suresh/doc/'

I am looking for a standard function which will return the location of b
relative to a i.e. '../..'

I have gone through the os and os.path modules, but could not find any
function of use. Should I write my own?

Thanks in advance,
Suresh

Don't write your own. This is yet another thing that Jason Orendorff's
path.py module can do easily:

from path import path
b = path('/users/peter/')
a = path('/users/peter/synergy/tiki.txt')
a.relpathto(b)

path(u'..\\..')

Jason Orendorff's path module has a method for this (relpathto()).

pathutils has a function to do this (actually extracted from the path
module).

All the best,
