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,
