code: def findpath(target, start=os.path.curdir):

  	return os.path.normpath(os.path.join(start, target))
docs: r"""
  	Find a path from start to target where target is relative to start.
  	
  	>>> orig_wd = os.getcwd()
  	>>> os.chdir('c:\\windows') # so we know what the working directory is
  
  	>>> findpath('d:\\')
  	'd:\\'
  
  	>>> findpath('d:\\', 'c:\\windows')
  	'd:\\'
  
  	>>> findpath('\\bar', 'd:\\')
  	'd:\\bar'
  
  	>>> findpath('\\bar', 'd:\\foo') # fails with '\\bar'
  	'd:\\bar'
  
  	>>> findpath('bar', 'd:\\foo')
  	'd:\\foo\\bar'
  
  	>>> findpath('bar\\baz', 'd:\\foo')
  	'd:\\foo\\bar\\baz'
  
  	>>> findpath('\\baz', 'd:\\foo\\bar') # fails with '\\baz'
  	'd:\\baz'
  
  	Since we're on the C drive, findpath may be allowed to return
  	relative paths for targets on the same drive. I use abspath to
  	confirm that the ultimate target is what we expect.
  	>>> os.path.abspath(findpath('\\bar'))
  	'c:\\bar'
  
  	>>> os.path.abspath(findpath('bar'))
  	'c:\\windows\\bar'
  
  	>>> findpath('..', 'd:\\foo\\bar')
  	'd:\\foo'
  
  	>>> findpath('..\\bar', 'd:\\foo')
  	'd:\\bar'
  
  	The parent of the root directory is the root directory.
  	>>> findpath('..', 'd:\\')
  	'd:\\'
  	
  	restore the original working directory
  	>>> os.chdir(orig_wd)
